I recently tried how far I can push my monitor via custom resolutions in Nvidia settings and settled for 75Hz refresh rate. I have no problems in any game except AMS, where I can't choose 75Hz in the config tool. I tried to manually enter 75Hz, but it defaults to 60 again. Checked it with my monitors OSD and yup, game runs at 60. What can I do now? EDIT: Just checked, same with rFactor 2
Fixed. Added 1080p@75Hz with this tool and restarted the video driver. Custom Resolution Utility (CRU)
