mine is 8gb too… i didn’t know much about this and have taken 3050 rtx card which has 8gb vram only. a good project takes up 2.5 to 3 or 3.5gb of vram and if you run 120fps and with 100 hz 2k display (all these too take up some vram) thus causing pc to go out of vram and causing crashes. So, i reduced to 1920*1080, 60 hz, 60 fps on nvidia panel and currently i constantly check for vram usage whenever i use unreal but crashing problem gone just like that.
