I have an issue where I am not able to run the resolution 1280x720 at 75hz, but I can run all other resolutions at 75hz. I am setting this in the Custom Resolutions section in the latest crimson drivers.
I have a Radeon 7770 and I have been able to run 720p at 75hz before in Counter-Strike. My desktop res is 1080p@75 but as soon as I load CSGO at 720p it defaults to 60/59 hz.
Help is very much appreciated
