Got my pc for 600 euro
Idk what is ur problem, clean it . Install cc cleaner, delete all shit files. Get some program to check maybe u got some virus on PC so make sure u get some malvare programs to clean it. Update drivers, set up ur nvidia settings to high perfomance, set up ur PC to high perfomance. Turn of 8 MSAA , if u need it put 2 or 4. For that pc 8 is too much.
