Summary0000598: Support for 47 hz and 48 hz
DescriptionRecent NVIDIA drivers have made it extremely difficult to use my nearly-perfect 23.976 hz custom resolutions. NVIDIA created a 23.9775 hz, which conflicts with the 23.976 hz settings I've been using for the last 3 years.

I cannot play 24 hz and 23.976 hz videos if I create a 47.952 hz custom resolution (see additional information for my reasons for doing this).

My workaround is to create a 47.952 hz resolution. Unfortunately, MadVR fails to use this if I also have 1080p24 in the display modes line.

If my display mode line contains 1080p47 but does NOT contain 1080p24, it works fine. If 1080p47 AND 1080p24 is defined, MadVR always selects 1080p24, which is incorrect and I get repeated frames.
Steps To ReproduceDefine a 47.952 hz 1920x1080p custom resolution. Assuming late version NVIDIA drivers (399.24 and later is a good baseline). This mode works on my Sony HW40ES projector, which was very surprising.

Add the following to MadVR Display Mode: 1080p47, 1080p24.

Play a 23.976 hz video file. MadVR will always select the 1080p24, ignoring the proper 47.952 hz, resulting in repeated frames.

Edit the Display Mode to only contain 1080p47. Now the 23.976 hz file plays back at 47.952hz as expected.
