The problem
The first time I encountered this problem was the 1st TWW patch that was deployed on the live servers. At some point while I was playing the game, once I opened the map/moved the cursor over the questlog my game completely freezed and started to resize every 5 seconds. I had to completely restart the game (or do a /reload while the game was resizing/freezed & be4 the next “resizing” moment it was working for a second so it did the reload).
The solution
There are new graphics options if you scroll down in the Options → Graphics menu.
Switching to DirectX11 from DirectX12 most likely fixed the problem for me. However, I had to disable the “Async Resource Creation” option as well, because my 1060 (explanation below) had barely 45-50 FPS in a dungeon while I was running the game. After disabling that, I instantly got back to 75 FPS (that was my limit set). So far I’m so happy I finally found how to solve this problem, so I hope I can help some1 fixing it as well.
My setup
CPU: Ryzen 7 5800X3D
GPUs: 3060 Ti & a 1060 3GB cards.
