But when i reset my PC (to downgrade from Windows Insider builds), updated my AMD drivers, i found performance to be terrible and I can't understand why. I just fully dusted my PC, to no significant change. GTA IV, on low settings, runs at around 45fps and for reference, before resetting, GTA V ran on very high settings at 60+ fps.
The only thing I can think of is a motherboard BIOS update? It was pre-updated when bought, so maybe the reset undid it? Any help is appreciated and this is my last resort, I've tried looking online for a few days for help. Thanks.
