DirectX fullscreen refresh rate is capped at 120 Hz

[johanssonmarcus]

With Windows running on a 144 Hz or higher monitor, my refresh rate will change everytime I Alt-Tab to/from the emulator, since the emulator is running in 120 Hz for me. If I uncheck "Auto" under Monitor Frequency in Video Options I get 60 Hz. (Switching the resolution, of course, is slow and flickers a lot so it would be nice to avoid.)

I checked the source a bit and found in NstDirect2D.hpp (Line 72): MAX_RATE = 120,
which makes my native refresh rate resolution be removed from the list of resolutions in the EnumerateAdapters method.

Unless there is a reason for limiting this to 120, maybe it's an easy fix? There are even some 360 Hz monitors now so I think it might be best to not limit it at all for future proofing.

I just thought I would mention it. Anyway thanks for the great emulator!

Thanks for pointing this out. I also have a 144Hz monitor, but I usually run at 120Hz. I think maybe I will just remove any refresh rate limitations altogether. I'll take care of it the next time I merge the upstream core code in and prepare for the next release.
