Item frames cause massive fps drops with RTX GPUs

Hey! Thank you for your report and patience! 

 Can you upload your world file?

Thank you!

Hey

The world is to big to upload here, so i uploaded it on google drive

heres the link:

Thanks for the information. Do you feel that this is this a new issue, or was it occurring in previous versions such as 1.17 as well?

I just returned for patch 1.18, but when i was playing 1.16 i didnt have this issue.

This World i started on Java and havent experienced any fps drops with the Storage, i then converted the World to bedrock so i can Play with rtx, then i noticed the drop in fps 

In case it helps to diagnose the issue: Which tool was used to convert the world?

I used Microsofts chunker

I feel this issue is somehow effecting only certain devices or hardware specs.

I will make an example world to share soon, But for now I'll state my observations. On a server I play on, one persons storage room causes some players to drop to 30fps or lower. Their storage room has hundreds of item frames with items in them. She never used to have issues there herself (running on a GTX1650) . But she recently upgraded to a new computer and now has an RTX 3060 card. Now she also has noticeable fps issues. I also upgraded from an old laptop, to a new computer with an RTX 3050, and I now have fps issues where I didn't before. Similarly another server member with an RTX has the frame drops (waiting on exact specs). I have also sent someone with an RX570 there and he ran at his standard 60fps the whole time and no issues.

In a test world, I filled a 25x25 area with empty item frames. And didn't have any fps drop.
once items are placed in the item frames I would drop from 60fps to 35fps.
I also tested with the same area using signs with full text (just the letter a until it wouldn't fit). this area lowered my fps to 10
hitting those signs with glow ink would further drop fps to 4.

I'll run the tests again on a fresh flat world and compare what hardware devices I have access to and update again with the results as well as the world download. My initial suspicions are that something is causing incompatibility with ray tracing capable cards when it comes to item frames and signs.

These worlds are running 1.19.10 But I believe the issue is older than that, we're just noticing it because we're upgrading our computers.

Could have the same root cause as MCPE-111547, since the issue seems to be rendering the items, not the frames.

Here is a world I have prepared to do some comparison testing. I have tested this on all the devices I have available to me and had several other people also test. While I'm not an expert on computer hardware, it did seem in general that the better the GPU the worse the performance, with some other variance for the capability of the rest of the device. Test world has area's spaced out with 625 of each test item in it. the loose items test has droppers to fire items all at once should the last batch despawn, items are spaced out so that they don't combine and stay as 625 individual items

I did include some comparison tests. One for loose items on the ground and also for signs with lettering and glow ink (as a known issue comparison)

Most of the devices were restricted to 60fps.

In keeping with report formatting.
Steps:
1. load test world with Newer Ray tracing capable device. And also with another device with older gpu, or lower quality gpu
2. use a resource pack, or xbox game bar to view fps.
3. look only at 1 test location at a time and compare fps between two devices

Expected results.
the device with the better hardware will have better fps while looking at item frames with items in them, than the lower end hardware.

Actual results.
The device with the better hardware will have significantly worse fps while looking. or at least significantly worse fps drop. while looking at filled item frames than when comparing other test results.

Chests, hoppers, mobs, items, render distance... literally everything makes my game receive low fps on my RTX 3060.

To add to ArchThunders analysis I downloaded the testworld, copied the data from the chart, added two more devices and resorted the devices to compare RTX GPUs vs. non-RTX GPUs.
I think this way it shows strikingly how broken the performance is on RTX GPUs even when compared with integrated graphics cards, desktop GPUs or even the iPhone.

Best, Anzestral

Old text:
Hi ArchThunder,
I am also after this performance issue for almost 2 years now and have performed the tests with your testworld (I get almost identical results as your device 1, using an RTX 2070).
Can you provide the table such that I can include my testing data (I am planning to include more devices).
Also, I would like to sort the table with respect to the GPU (i.e. RTX cards vs non-RTX cards) to stress, that the issue comes from using RTX cards.
Thanks and best,
Anzestral
