Go to user.settings or the dx12 user.settings from your Windows Witcher 3 Documents and open the one depending if you play dx11 or dx12. Do the following:

AllowClothSimulationOnGpu=true
Tweak the "TextureMemoryBudget=" to half your GPU's VRAM
Tweak the following to this MaxTextureArraySize=1024 or 512 only if you still encounter issues and fps drops when u look at the ground after a fast travel or after a time of playing the game. After that:

AllowClothSimulationOnGpu=true
MaxTextureAnizotropy=16
MaxTextureSize=4096
MaxAltasTextureSize=4096
TextureMipBias=0 (This one is optional and helps with shimmering and flickering if you don't want to use TAAU)

All these change specific values in your TextureSettings and nothing else. You have the freedom to tweak anything else you want from in-game settings.


Open your local files.
go to TheWitcher3>bin>config>base>gc.ini

[Memory/GC]

; Disable triggering by object pool as this is not reliable now
DefaultPoolMemoryTrigger = 3000

Idk why the comment says that, but it seems to be working.


Following you open resources.ini

FileQueueSizeGame = 300
FileQueueSizeLoading = 700
MaxRequests = 45
MaxUncmpressedBudget = 240

Hope it helps anyone the way it helped me.
