Note: FPS can also decrease depending on how many chunks are loaded. The longer you look at something the more chunks could get loaded, the lower your fps might become, after how many seconds should the measurements be taken? The balancing of cpu resources might have also changed a lot last snapshot, amount of chunks loaded (letter C) should also be reported.

Using F3 as required (gives less performance, but still...)

Metrics report from 21w11a

Honestly. Since the 1.17 snapshots my whole game runs like crap. In 1.16.5 with no v-sync, no Optifine,15 chunk render distance I average at 200 fps. In the 1.17 snapshots and even worse since the OpenGL update I am struggling to even maintain 75 fps (my laptop monitor's refresh rate). Something seriously needs sorting. The game has notoriously bad optimisation as is and for it to get worse is totally unacceptable.

It seems that this has no affect or even improves performance on certain graphics cards. For my particular case, ignoring all prior snapshots and just comparing 21w11a and 1.16.5, I am having approximately identical performance.

21w06a severely impacted my performance, but 21w10a with OpenGL 3.2 brought it back up to par with 1.16. For some reason, 21w05b was much more optimized for my computer, and ran better than either 21w10a and 1.16.5.

Updating ticket because I believe the following information is pertinent: 

I had to reinstall windows recently for other reasons, completely solved my performance issues. 

21w08b: 146 FPS

21w13a: 108 FPS, 70 FPS and 29 FPS

Explanation: This turned out to be an odd one for me. Before I opened the test world in the latest snapshot, I deleted it and then re-extracted it from the Performance Test.zip, since I wanted to follow the exact steps again, as I read I had to repeat them for the latest snapshot. I then opened the freshly re-extracted test world in 21w13a and initially sat at 78-ish fps right after all chunks were loaded and then gradually stabilized to about 69-70 fps as the minutes passed. However, I decided to delete the world again, re-extract it again and open it again in the exact same snapshot just to be completely sure, because I had some tries before the first correct one (the first correct one being the one where I measured the 69-70 fps mentioned earlier) which were somewhat inconsistent with the steps (the only inconsistency I can remember was forgetting to switch to spectator mode, but there probably have been more before opening the inconsistent world), and showed a different fps probably for that reason (like 128 after the chunks were loaded, then stabilized to 104-110), but I'm not certain. But this time (the second correct one) I only measured 29-30 fps, which is quite odd given the fact that the 69-70 fps measurement was achieved by executing the same steps, so I'm not sure what's happening here, but I'm mentioning it because I'm trying to be as helpful as possible (but am probably failing horribly).

Hi guys! Unfortunately I did not see this issue before opening mine (MC-225941) ! So I eneded up making a costum run on a benchmark world I made and I used 16 as rendering distance which underlines the problem a lot better than 12 chuncks on my system. Also I run the "benchmark" in the latest release which also uses java 16 instead of java 8.

Here I re-post my report so everything is tidy and in one place:

 
I did some testing using the integrated frametime counters inside minecraft accessible via F3 + ALT

The device specification are as follows: Core i7-8565U and Nvidia MX230, the gpu driver version is the latest up to date: 466.47, windows version is 21h1.

Testing methodology

The test was run by using a client created via the launcher based on minecraft 1.16.5 with the default java (8) and another one created in snapshot 21w20a with the default java (16.0.1). Both clients received 8 GB of allocated RAM on a system total of 16GB DDR4 running at 2400mhz CL17 running in dual channel. No applications where running in the background while running the test.

To perform the test I created a world in 1.16.5 and made a minecart railtrack to be able to standardise the logging. I let the game load all the chuncks in the track at least once after I finished building the track and then I closed the game after putting myself in the minecart in the orientation to run the benchnark and then I closed the world, I run the optimise world and made a backup of it in order to be able to re-use it for further snapshots under the same conditions. I extracted another copy and optimised it in 21w20a to convert it. At this point I started benchmarking: I waited precisely 10 seconds after being spawned in the minecarft for the fps to stabilise and I begun logging and started moving with the minecart.

Furthermore I created the same world in 21w20a with the seed (no datapack) and I made the same track and I compared the results to world in 21w20a but converted from 1.16.5, both tests on the newly generated and converted world gave the same results so they are functionally the same and I will report on the converted world for simplicity also for further snapshots in which I will use a converted from 1.16.5 world.

The settings where smooth lighting to maximum, max fps to unlimited, vsync off, render distance 16, biome blend off, particles to all, entity render distance 150 per cent, fullscreen on at 1080p, clouds on and graphics was set to fancy. Via the gamerules I locked the daylight cycle, time was set to noon, weather was set to clear and mob spawning was not allowed. No mobs or items where in the benchmark rendered area because I used carefully the kill command to get rid of everything which was spawned before I type the gamerule to disable mob spawning.

Further update in comparison to the day after I created the issue: I did the same testing also by using the iGpu (intel HUD 620) and more or less the same performance degradation in percentage is experienced like what happens with the Nvdia dGpu. I have no plans to record the iGPU runs because I use the iGPU to record the screen and so this would impact the iGPU performance run, this latter does not happen when I record the dGPU since as I said it is the iGPU to do the recording job.

For further clarification I link the private youtube video I made about the 2 of the test runs I recorded.

NOTE: the clips only contain precisely the moment the cart starts moving and they end 2 seconds after going till the end of the benchmark run. The 2 benchmarks in the video have the same amount of frames and are exactly the same lenght.)

Here is the link to the private video: [https://youtu.be/QFO4NHPXb9M]

I am reporting this because Open GL 3.2 and Java 16 where introduced to modernise the game engine and to give developers new development tools. I know that Mojang has an eye of regard about how the updates can impact performance and I also know that the changes and bugfixes made with each update can change the performance and sometimes make the game run less well but only on the surface because the bug or thing which was changed was acting in an unintended and wrong way beofore the fix. Therefore personally I am fine with the appearent impact if the appearent boost we had before was due to something not acting properly, however I still wanted this to be brought to the attention of the developers just to make sure everything is acting as they intented in the current snapshots.

I hope this feedback can be useful.

21w08b: 19-20 fps (37-47 with settings turned down)

Might not seem like a big difference but on the new snapshots having the f3 menu or inventory open makes fps even worse than that.

So since my ticket was closed as a copy for this ticket, I would like to ask my questions here:

Quick recap: I'm working on a resource pack and it worked fine in 21w18a and prior. But when 21w19a came out with the new engine the game dropped to 0-1-2 fps, and I'm keep experiencing it in 21w20a and 1.17-pre1 versions. It doesn't help if I go deep or high.
I tried out other resource packs with similar high resolution (512 pixel) and they didn't cause fps drops. So I looked for the files in my pack that do cause them and I found that animated blocks became problematic. If I have mcmeta files for block animations, which were working in 2 snapsots ago (like kelps, shiny ores, lava etc) my fps drops.

So this new engine seems weaker to me in this situation. Is there any JVM arguments I could set up in the installation to work as in the previous snapshot and full versions?
My current line is this, but I'm not technical enough to understand every part of this:

-Xmx8G -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC -XX:G1NewSizePercent=20 -XX:G1ReservePercent=20 -XX:MaxGCPauseMillis=50 -XX:G1HeapRegionSize=32M

1.17-pre2 still has the bug.

FPS in 1.17-pre3: 78

OS: Windows 10 Home 64Bit

GPU: RTX 3080

^{Edit 1: I forgot to mention, this bug also causes a ton of micro-stutters. This makes the game report a MUCH higher framerate than it actually is, as these stutters effectively make the game look visually the same as about 15FPS for me in some cases.}

I want to say that the problem is not only in the smaller FPS. There are a lot of microfreezes, which sometimes make it impossible to play.

I noticed that if the "Mipmap levels" setting is set to "OFF" microfreezes almost disappear, but this does not help with FPS. I hope this will help someone.

Since nothing would make the lag stop (minimap off didn't help me, smooth lighting off, etc.) I decided to open the performance tab in the task manager.

It turns out, the newer OpenGL only uses about 7% of my GPU, whereas the original OpenGL used about 32% of it on average.
So I'm wondering if the game is capped to only use a certain percentage of the GPU, or if it really is a bug, or if it's something about the new OpenGL itself.

Something odd to note is that the GPU usage goes up once you go out of fullscreen (for me, from 7% to 11% average,) and the FPS seems a bit higher (even when the window's maximized to nearly fullscreen size,) although the stuttering is by no means gone.

Either way, I think we should also include these statistics in our comments from now on, and hopefully this issue gets fixed soon.

Don't want to be negative about how this Jira report is going, but I think that reports done are not so useful.

The report is open and has normal Mojang priority so it means they are aware this bug report exists. I think that at this point we can stop hoarding numbers of our computers for a few reasons:

• the test being done is static: standing in 1 spot and measuring the "idle" fps does not represent how the game works or how we would play. A test using a moving minecart rail would be much more usueful with a frame by frame logging and not a mere avarage at the end of the test to report here

• settings are kind of CPU bound since the res. is 720p and chunck render distance is relatively low

• some results are quite odd and I think that are due to people having some issue with video drivers which they could solve by DDUing their drivers and then clean installing them again, also some results run on old drivers despite much newer ones being available for their GPU

• what we are experiencing may partly recoverable but it is definetely not a bug since the engine has changed and also chunck culling has changed so it is debatable whether we are loosing performance or the one we got before just higher due to less accurate chunck calculations or some other bug

At the end of the day the devs have their pcs too and they can for sure test performance on theirs and get complete and more accurate and more useful data compared to the one we could ever provide here and they have all the insight needed on the game changes and game engine itself.

So I would say that since this "issue" has been noted by Mojang which is the whole point of opening this thread we can for now stop reporting numbers since they will look into it and numbers here do not help them sort this out in a better or faster way.

🙂

Amazing gaming experience since 1.17!😛

I think the problem will not be solved until the release, because there is only a week left. Method with exiting full screen is working. Before was 40-50fps, after - 65.

@Archer Legend brought up a good point about outdated drivers.

— some results are quite odd and I think that are due to people having some issue with video drivers which they could solve by DDUing their drivers and then clean installing them again, also some results run on old drivers despite much newer ones being available for their GPU"

I went to Nvidia's GeForce Experience and did a reinstall of all drivers, and 1.17 seems to now work nearly just as good as 1.16. I guess it means that manufacturers are actually the ones to blame if this really is the root of the issue, as they evidently aren't shipping out PCs with compatible drivers.
(thank you archer legend)

@unknown, we've been told by Mojang to create this bug report specifically to collect performance benchmarks, so that they can properly gauge what kind of impact the changes to OpenGL have.

dan hop, I'm quite sure that is a completely unrelated issue because:
1. This report requires you to stay in spectator mode and stay still to reproduce, therefore not crossing any chunk borders; and
2. This issue first appeared in 21w10a with the rendering changes, while the issue you linked dates back to 1.14.

The game in singleplayer has become unplayable for me at this moment. There needs to be done something!

I dont think its weird that people are getting around 100 fps with these settings. I think most people play in normal 1080x1920 resolution. In normal 1080 resolution the amount of FPS will be lower then the 1280x720 resolution.

If the number in front of the driver version is the OpenGL version, then it seems 1.16 is using a newer version than 1.17 for some reason. Both are using the default launch parameters & settings, as well as the same config file. Weird!

With my normal settings of 16 chunk render distance at 1080p, I'm getting constant drops to the 40fps range in my survival world, and reducing the render distance barely helps, unfortunately.

Honestly, the main reason I've found this issue is because of the dramatic drop in shader performance with OptiFine. I did the above tests with the Vanilla game though of course! It looks like Vanilla performance has actually improved for me. I've seen quite a few people complaining about drops in performance on older, perhaps now unsupported hardware though. I guess for me there's nothing wrong with the base game, so I'll go ahead and hope that the final release of OptiFine improves the performance again significantly.

Can confirm 1.17 versions and recent snapshots have considerably worse performance than 1.16.5

Used to be able to have 60 fps constant and 60-40 fps with BSL shaders in 1.16.5 with 10 Chunk distance , Fancy , Entitiy range 75%

Barely 50-30~ in vanilla no mods and with Optifine / Sodium in 1.17.1 same settings as above (and with BSL shaders it's barely 20-10 fps now)

Also barely 50-30~ in 1.18 snapshots no mods (obviously) same settings as above + new rendering and simulation options don't seem to help much at all.

Aye something is definitely wrong when even Optifine or Sodium can't fix the performance issues in 1.17.1 compared to huge boost they gave in 1.16.5

I really hope this is possible to sort out without me needing to buy a new PC

Can Minecraft please deal with this? I hate how nobody is even assigned to fixing this issue.

Does resetting my pc help with this? I've heard it somewhere.

This has been an issue for months now... Have as anyone from the dev team even had a look at this forum yet ?

@unknown, as was mentioned in previous comments, this report's main purpose is to gather information. Comments that are not directly contributing helpful information should be taken to the linked subreddit. Seeing as you previously indicated your issue was resolved with updated graphics drivers (at least for 1.17), I'd recommend you provide new profiling details, along with screenshots, as per this report's instructions.

Note: I accidentally set it to 1280x768@60 instead of 1280x720@60, but the relative results should still be clear.

1.17.1 Profiling: 

From what I've seen, the upgrade to OpenGL hasn't done too much, although it still causes some performance loss. However, it's clear that the current rendering engine can't keep up with 1.18. I loaded up the 1.17 performance world and got nearly the same results. However, when I load a world made in 1.18, the rendering engine can not keep up.

Average FPS in 21w42a with 1.17 World: roughly 150 FPS
21w42a Profiling: 

The game seems to be running smoothly- just like 1.17. Doesn't seem to be too different from 1.17.

In 1.18 worlds, the game is quite laggy in general while moving around. Staying still is fine for me, but actual gameplay comes with tons of stuttering and lag. Raising the RAM to 4GB helps, but still results in quite laggy gameplay.

Since both 1.16.5 and 1.17.1 were released after snapshot 21w10a I made an extra comparison including 1.14.1.

My ingame graphics settings are default.

1.16.5 results in "PerformanceTest1_17" world

1.17.1 results in "PerformanceTest1_17" world

As you can see there are just little differences between 1.16.5 and 1.17.1. Both are really bad results as you can see in the following comparison.

1.14.4 results in new generated world

1.16.5 results in new generated world

1.17.1 results in new generated world

Compared with the older OpenGL version from the 1.14.4 version of Minecraft the newer 1.16.5 and latest 1.17.1 are really bad.

It seems like the new snapshots are improving performance, at least for me. It seems to have fewer lag spikes.

Can confirm in 21w44a. This snapshot is significantly laggier for me than 21w43a.

Hmm for me 21w44a seems to have a little less fps problems than 21w43a (still not nearly as fps good as 1.16.5)

I was not having any issues until a few days ago.  Before I found this thread I tried several things on my own to resolve the issue including: updating video card drivers, clearing space on my HD, optimizing HD, running a full virus scan (couldn't hurt). removing all mods.  making various updates to video setting in game.  Nothing seems to help.  FPS jumps around from crazy high 800+ to crazy low 9.  

This is a very serious problem, which causes at least 60% performance loss.

Using VisualVM, I found that glBindVertexArray took up a lot of CPU time.

I think this is caused by frequent OpenGL calls after glBindVertexArray, such as glBindBuffer, glEnableVertexAttribArray, glVertexAttribPointer. 

VAO only needs to bind its attributes once, and then it does not need to bind every time it is drawn.

Finally, a large number of drawing calls will also cause performance loss. Try merging vertex buffers into one.

From r/minecraft on 1.18pre6 and 1.18pre7 (someone else's comment not my own):

"Performance in 1.18 prereleases is still abysmal because the renderer has not been improved to compensate the change in worlds, neither for the shift to GL 3.1, nor for the rather simplistic approach to vertex storage and draw calls. The renderer "worked" for for pre-GL 3 because device drivers for old GL versions are optimized around assumptions that held for compatibility contexts, but those optimizations are not present anymore because more responsibility to be efficient with GPU object usage and draw calls is shifted to the application in GL 3. No matter what you do, today's Minecraft JE rendering is severely limited by single core performance and GPU bandwidth because of the excessive draw calls and buffer property rebinding, and even high end CPUs can't provide enough headroom for that."

Still somewhat unresolved for 1.18 live release.

Performance is still really poor compared to 1.16.5
