I'll start by saying that I don't know exactly how some settings work, but there is no significant visual change after adjusting, and performance is significantly increased or stabilized. To enter the settings, press X + ALT and if you are in User Graphics Setting, click on the Developer Setting Menu button at the bottom left.
I have three suggestions for avoiding lag from overflowing VRAM:
- Setting DLSS performance to max;
- Enable Minimize BLAS Merging;
- Texture steaming reduction only in percentage, not GB (normaly is on 50%). Not sure if it helps but in a desperate situation you can reduce it to 10%.


I hope these things help you and I hope more negative reviews change this absurd situation.
