yes, create custom resolution with RR 60Hz, chances are, most likely that it will not work in games..., it's some sort of bug with windows or nvidia drivers (or both). You can also try some older drivers for that, but again, i don't know if GTX 570 is supported by drivers that can change it. Anyways, in Win 7, after SP1, i was unable to force custom resolutions in games. If you have a copy of Win XP, you can install it (64-bit edition for you) and use reforce or other 3rd party programs that will work perfect.
Maybe we should point that out towards nvidia, but i doubt they will bother with it. It would be nice to have a option to disable all resolutions except custom, and force driver to use only custom resolutions on games and desktop.
