At least I was able to open Task Manager and end it. The freezing might be Fortnite related now, not the patched QEMU. It was worse with the patched QEMU, couldn’t even open the Task Manager.
Oh yeah, it’s not running out of VRAM, it was only using 2 GB, it has 4 GB. That’s an error I was getting before, probably didn’t wait long enough to get an error. No need for a new video card then.
