make sure all background apps that are not needed for your O/S to function are disabled, mainly any anti virus, firewall or other resource hungry apps. i cant really suggest anything else for the settings because there isnt really much you can change for speed with what you are already using. if you want to you can try the "fast" preset but using that could produce glitches if it enables/disables certain things so if you do use it, pay attention to what settings it changes compared to what you have currently. you could also try using a software plugin or another emulator like psx.
