Summary0000477: Switching display modes with madVR ignores custom res/refresh rate
DescriptionWhen using madVR to automatically change the display mode, it seems to switch to the default Nvidia profiles and ignores the custom resolution/refresh rate I set via the Nvidia Control Panel.
Steps To Reproduce1. Create custom refresh rate with a refresh rate of 23.976 and resolution of 1920x1080 with the Nvidia control panel.
2. Add it to the madVR display modes for automatic switching
3. Launch a video, CTRL+J shows it is still running at ~23.970 and ignoring the new resolution made.

Just to add: it seems like this issue is only present when using DX11. It switches to the proper refresh rate in DX9.

I'm not sure if there's much I can do about this. In D3D11 I can't just request e.g. 23p or 24p. I have to request 24000/1001 or 24000/1000, and maybe the driver skips the custom resolutions in that situation? I'm not really sure, though. I'll have a look at that later, when I find some time.

No prob. Thanks for looking into it, it's much appreciated. I've switched back to D3D9 in the meantime and haven't noticed much difference to be honest.
