AMD Graphics card barely works?

Hello, since the update 0.23 my rx 6600 xt worked at 20fps no matter what, and there was lag but when i do something else while also having beamng in the background after a while it works normally, when i try to change windowed to 1920x1080 it goes back to 20 fps does anybody know how to fix this or if its gonna get fixed in later updates?

 

How's it perform on 0.24.1?

 

There's a known issue with AMD GPUs, you should read this post and reply with your data: https://www.beamng.com/threads/performance-issues-with-amd-gpus.82716/
Hope this will be fixed soon too.

If you have an issue with AMD GPU, you should reply to the linked topic with the data requested by developers in the first post.
The issue you report looks like a GPU clock issue (lowering frequency like if it was going to idle mode) and that's also what some other users report. Your data can help resolve this issue.
