After I alt tab to use DIM when I click back into the game D2 stutters, the screen freezes and frame rate drops from 175 fps to 20-30 fps and it takes about 10 seconds to finally recover. Essentially can't do anything within the game and just have to sit and wait. Never had the problem before Lightfall.
PC- Win 11 pro, Intel i9 5ghz 10th gen cpu, Geforce RTX3090 ti FTW3, 32 gigs ram Hyper x, 2 tb m.2. All drivers are up to date as is win 11. Anyone else having similar issues? Really need a fix.
