I Would use it whit a pc CRT.Xyga wrote:Depends what you expect from GroovyMAME, if it's for a CRT setup, then nVidia is a bad pick because they're not compatible with CRT_Emudriver, and the latter is only for AMD cards.
With nVidia cards you can use Groovy but not at any refresh rate you'd wish, you'll be limited to a small number fixed custom modes, something like 10 modes, on which all games will lock on to, producing an approximately 99% refresh speed accuracy.
(assuming your version of the nVidia drivers let you create custom resolutions)
Moreover that will be at a fixed native resolution for either a LCD (if that lcd supports non-60Hz refresh rates) or a simple PC CRT.
You could eventually get 15Khz output the old way using Soft15Khz, but it's a really obsolete method I don't recommend.
Much simpler is to get an AMD card with an analogue VGA or DVI-I output (the 'I' is crucial), there are many from the old Radeaon HD series to the later 'R' series that feature those.
Still bad choice?
