The game works fine on my computers for several days until yesterday I found that it will freeze randomly while I playing, the sound is normal, just the screen will freeze and I cannot do anything, if I switch to another window, the screen will resume and the game looks like fine at background, but when I switch it back, the freeze appears once again and again and again and occurs so frequently (less than 30 sec) that I cannot play it anymore, I tried to reinstall it and doesn't work, after I install the 1.05 patch(which is the 1.7GB one that downloaded automatically on steam), it STILL happens but look a bit different, now it will first profoundly reduce the fps into a single digit(where the original should be around 60-90) for about 10 seconds and then freezes, I have tried to reinstall my graphics driver and still nothing happening, my game is running under 1.05 patch on RTX 2080Ti with driver version 460.89, CPU is i7 8086k@5.0GHz, and RAM is single 16GB 3000MHz, system is Windows 10 Professional Edition 20H2(10.0.19042), I've been annoying for this problem for 2 days and I want to get some help
