RTX performs well on 1.17.2 , but when I update to 1.17.10 , it suddenly become slow and dark. Bellow are two screenshots. As you can see in the pictures below, the rooms are dark while they should be quite bright on 1.17.2
[media]Another issue is that FPS was about 70 on 1.17.2 while it drops to about 58 on 1.17.10 . Also Minecraft crashed a few times, so there might be some performance problems on RTX.

Yep, I use RTX3060 Laptop GPU. At first I thought my GPU drives went wrong, but as more friends had the same situation I realize that it might be a bug.

Same with RTX 3080, random crashes… Even without rtx when 1.17.10 dropped..

After a few weeks of playing, I can say that version 1.17.10 has quite a lot of performance problems, both with and without RTX. Minecraft shouldn't be a game with high hardware limits. We need to report those issues to mojang, and persuade mojang to optimise the game so as to adapt to more devices.

Couple notes I've seen:
I seem to hit this most often when it switches between day/night. Where the path tracing model would "reset", but just never come back up to proper light levels.
Workaround seems to be disabling and re-enabling RTX using ';' when encountering this bug.

Affects beta 1.17.4020

I don't know why it said fixed but I still experienced it in 1.17.30

Happens to me without RTX enabled! Dont know what to do, I cant play anymore

This is back in 1.19.20
