[MC-36841] Major FPS Issue

Trying this bug report thing again. This is a major issue. I have screenshots to support the report this time. In the newest updates 1.7 prerelease and 1.7.1 I am still experiencing major FPS issues. The memory used rarely goes above about 15%. In the last version that I was able to play (13w39b) I don't have this issue at all.

One thing I noticed is that in the version that works (13w39b), my FPS stays about the same when paused and when in game. In the version that doesn't work I have low FPS in game, but in the pause menu, my FPS goes up to what it usually is (or better) in the version of the game that works.

What has changed in Minecraft to cause such a drastic issue with my FPS?

I get this as well, it started post 13w39b. It only happens in a village for me (naturally spawned but expanded door wise). I see the memory use going up quickly, FPS goes to 0-4, then after ~15-20 seconds it goes normal again. It repeats about once a minute. crash report attached.

Seems to be pretty similar except mine is constant and never goes back to normal and happens wherever I am in the world. I really hope that some folks have some suggestions on how to maybe fix it ourselves other than the standard reply of "get a better computer"

I've tried everything I can think of, but I'm sure there's something I'm overlooking.

If a quad core i7 with 24 gb of memory (2 dedicated to the JVM) and the app running of a striped set of SSDs I'm not sure what more I can add without spending hundreds on SLI'd video cards.

Bill Robertson 2013-10-23T21:57:58Z

Wow, makes me feel better knowing that a much better computer is having issues. Horrible that the issue exists, but glad to know it's not just me and my dinosaur.

Bill Robertson 2013-10-25T14:07:55Z

Issue still present in 1.7.2 I did get my FPS to jump up to 19 for like two seconds in game before it dropped back down to 0-3 FPS, though.

change max framerate to the max!

Bill Robertson 2013-10-27T02:13:08Z

I'll give that a try and report back tomorrow.

@David Truog:

OpenGL: GeForce 9600 GT/PCIe/SSE2 GL version 3.3.0 NVIDIA 304.88, NVIDIA Corporation

Update your driver http://www.nvidia.com/download/driverResults.aspx/67567/en-us and report if that changes anything

fienxjox 2013-10-27T18:20:41Z

Updated drivers to 319.60 from Nvidia's site. Ensured all else was updated. Now on MC 1.7.2. Issue still occurs, new screen shot and forced crash report attached.

Bill Robertson 2013-10-27T20:26:06Z

Small improvement today. Instead of 0 - 3 FPS, I am getting about a consistent 8. Still not where it should be, but that is progress, at least. Don't know what changed on my settings, but my son woke me up this morning to tell me that we were getting 8 FPS on 1.7.2

I, too, have noticed a difference in performance between 1.6.4 and 1.7.2. In version 1.7.2, I'm experiencing a low frame rate and jerkiness. My rig has a 3-core AMD processor with an Nvidia 6800GS, 4GB RAM, Windows 8. I tried the following things with no improvement:
-Updated Nvidia drivers to Geforce 307.74
-Updated Java to the latest revision
-Completely cleaned-out all files under appdata%\.minecraft – except for saved games.

When I run version 1.6.4, I see fairly fluid movement with fps ranging between 40-60. When I run in version 1.7.2, the movement lags and fps is unstable, 26fps max. Movement is jerky when walking – even after minimizing graphics settings (i.e. decreased particles and chunks)

I feel we are no longer looking at merely client side FPS issues, actually. I'm just experimenting with a private server at the moment and these lag issues occur for the server as well. Average tick times increasing by a factor of 200% - 300% without any discernable cause and while being the sole active player.

If I then simply walk away from wherever it was I experienced these tick spikes, it returns to normal. Something that had been loaded obviously was causing a major spike. But, again, nothing visually apparent. Like the issue I reported (which turned out to be caused by persistent arrows, hundreds of blocks away from me), there seem to be entities which cause severe performance issues.

Something is quite peculiar about 1.7.2; I feel more testing was prudent before releasing it.

Just curious if anyone is experiencing this around the 12 chunk line? (F3 shows what chunk you are in)

Torabi 2013-11-22T18:21:18Z

Try the profiler (Shift+F3). Drilling down into the different sections (using the 1-9 and 0 keys) can help pinpoint what is actually causing your performance problem.

Jonathan Williams 2013-11-27T00:17:49Z

Have you guys looked into Leaves decaying causing this issue? I'm part of the developer team on a really large network and our new gamemode does an infection type thing across the maps. Once this hits the leaves and converts leaves to another block we get the 0 fps drop in 1.7.2.

If its leaves changing that causes the 0 fps then this could explain every single scenario put into these comments for this bug.

fienxjox 2013-11-27T00:33:16Z

@Jonathan Williams

I can safely say that in 99% of the cases this has happened to me there were no leaves decaying in the area.

8j0KVEUciir2 2013-11-27T00:56:20Z

Same here; deep below the surface of a Mooshroom Biome bordering a very open Plains Biome and an Ocean Biome, no trees for quite a number of blocks. Which is not to say the two issues are separate. It could very well be a symptom of the same issue in both cases. But, I would be rather surprised if this somehow all led back to just leaves.

Jonathan Williams 2013-11-27T01:06:29Z

Btw, these weren't just leaves that were in render view. They only had to be in chunks that were in range of the client as the leaf blocks were changing.

fienxjox 2014-01-25T18:15:03Z

I am not experiencing it as of 14w04b, however I have made sufficient changes to my world since this was reported that I cannot say what may have fixed this.

fienxjox 2014-02-01T18:23:59Z

Ok, just got hit again today for the first time in a while. Snapshot 14w05b. Not super close to where I had experienced it before (a village, the few you see in the crash report are in trading stalls). Went down to zero FPS and stuck there for at least 20 seconds before I could get a forced crash which is worse than I'd experienced before. Will continue to monitor.

Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases. If this has been done, we can reopen the issue.

Keep in mind that the "Resolved"-Status on this ticket just means "Answered", and that we are waiting for further information on whether this issue still exists or not. We will reopen it as soon as the requested information has been deliviered.
