I see. But when I try to open like AC Valhalla, normally I got 90-100FPS. But RN, it's only giving me 50-60FPS. It's weird to have that kind of frames especially when you're only playing at 1080P resolution. I guess i'll try to reformat my pc and install a rollback driver, again.. Btw, thanks for answering my query bro. Appreciate it.
