Moderator Notice

As of snapshot 21w10a, the game renderer has been updated to use newer OpenGL features. For some users, this may result in a loss in performance (FPS) in 1.17 and above. To gauge the impact of this, standard information is requested from affected users. Please follow the instructions below, and leave a comment with the results, as well as details about your system information.

For any discussions about this topic, please do so on the linked reddit thread

Before proceeding, please be sure to update your system's video drivers per these instructions. If you need assistance with this, please visit our community discord server.

If you experience this issue, follow these steps

Download the attached world file PerformanceTest1_17.zip, and extract the world into your saves folder
Open the game in version 1.16.5
- Ensure the default amount of RAM is allocated (1GB 32 bit users, 2GB 64 bit users)
- Be sure to use the default Java or Java 8 runtime

Use the following standard video settings:

FOV: Normal (70)
Fullscreen: ON
Fullscreen Resolution: 1280*720@60
Biome Blend: 5x5 (Normal)
Graphics: Fancy
Render Distance: 12 chunks
Smooth Lighting: Maximum
Max Framerate: Unlimited
VSync: OFF
Clouds: Fancy
Particles: ALL
Mipmap Levels: 4
Entity Distance: 100%

Open the Performance Test world, and wait for the chunks to load (you may need to switch to creative mode and back (press F3+F4 twice)).
- If for whatever reason you need to re-create the world, please use the in-game "re-create" option to preserve the seed and game rules

Reset your position:

/execute in minecraft:overworld run tp @s 188.76 98.90 -209.60 179.85 35.10

Change your game mode to spectator:
```
/gamemode spectator
```

Open the F3 debug menu, and wait a minute for the FPS to stabilize
Note down your average FPS
Repeat these steps with the latest snapshot
- Here, also press F3 + L to generate a profiling report (only applicable in 21w11a and up)
Leave a comment on this report with:
```
FPS in 1.16.5
FPS in the latest 1.17 release (please specify the release version)
Your operating system
Your CPU
Your Graphics card and driver version, as reported by the game
Your profiling zip file
```
It is also recommended to take a screenshot of the F3 debug menu and attach it to this report, to ensure that the correct GPU is accurately reported (particularly in cases where more than 1 is available)

See here for an example comment.

Reminder: If you leave a comment, please follow the instructions above and include your approximate FPS averages. This helps with effectively diagnosing this issue.
