Re: Low GPU Performance
Make sure GSync is enabled in compatibility mode.
Also activate Vsync in the driver settings for Apex Legends. Disable Vsync ingame.
Enable GPU scaling in the driver settings.
Enable Nidia Reflex in Boost mode in Apex legends, don't cap framerate otherwise (only if you should exceed 190 fps). It works even better for me if I deactivate Nvidia Reflex with the start command. Strangely enough, it still remains active, but the micro lags have disappeared.
