Platform
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.

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.
- 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.
