Shader Quality

[danadi712]

Hello!
I have this problem
i am playing some mods on win 11.
XRM and XTENDED.
I put from game launcher /Graphics Settings /Shader Quality on HIGH.
Any time when i enter in some sectors (a few of them) image become pixelated.
Then it recover, then became pixelated again.
Fluctuate lets say 10 seconds and then freeze with my entire PC.
If i put Shader Quality on LOW i dont have this problem.
Only on HIGH and MEDIUM.
Thank you!
PS
I didnt have this problem on WIN7.
And older graphics card
I changed my system 2 years ago.
I haveAMD RX 6650T and AMD RYZEN 3600
