Thanks to the Author, resizing the window really helped a lot.
I came back after 3 months and my engine already started while downloading the update.
Unfortunately, radeon chill from the driver software did not help to cap my FPS.
98% gpu usage while installing an update (few hrs, ~120GB) and Devs dont care.
Its time to fix this *’%+% ! Will the devs wait until the first few graphic cards die while installing the game to fix this issue? It shouldnt be such a big problem to set an fps cap for the menu…
