I recently switched to windows 10, and have noticed a significant performance decrease, compared to running it on Windows 7 (Ultimate). MY PC Specs: Processor: AMD Phenom II - clocked at 4.0ghz. RAM: 16gb - clocked at 1600mhz. GPU: AMD R7 370 Overclocked Edition. (GPU clocked at 1030mhz - Memory clocked at 1400mhz.) Latest drivers (including Radeon Crimson) have been installed. (probably not as important, but 700watt power supply, 250gb HDD, 3TB HDD <-- ps2 is not installed on this, for it is slower) In game settings are on High with the exception of the following settings Shadows - Low. Particles - Medium Effects - Medium (probably not as important, but 700watt power supply, 250gb HDD, 3TB HDD <-- ps2 is not installed on this, for it is slower) So onto the question: Has anyone else had a sudden performance drop when playing PS2 on Windows 10? Compared to windows 7, the game used to utilize my GPU more than my CPU, but now whenever i'm facing a decently sized battle, my FPS tanks by at least 35 FPS (sometimes more) going from 60~50, to around 18~26 and i immediately become CPU locked. So far i've tried unparking CPU cores, lowering all graphic settings, reinstalling all my graphics drivers, reinstalling the game, etc so on, to no avail. Anyone have some potential solutions? Anything that i could try that would benefit me would be greatly appreciated.
