How to set Custom Resolutions (Super Sampling)

[Al]

For me personally, if it's similar to VorpX, then custom resolutions are crucial. Oculus / Vive native SuperSampling: Not so much.

+ I try to play VorpX games at 3200x2000 (16:10 aspect ratio) or 3200x2400 (4:3 aspect ratio)

DSR isn't a good option because you are losing the performance without much gain to show for it in VR. On physical monitors/projectors, it works well however.

Of course, 3200x2400 is well beyond the capability of my 720p projector primary display, but this is how you get it to work in VR (HelixVision / VorpX):

1. Use CRU (google) to install a custom resolution + refresh for your display, being careful to not go over the MHz pixel clock supported by your display. A safe value for 3200x2400 and below is 18 Hz refresh, Reduced Blank:

2. Reboot.

3. Add the same custom resolution in the nVidia control panel, at 18 Hz, Reduced Blank formula.

4. After clicking "Test", your screen will go blank because obviously your screen can't support that resolution. Blindly press the "Y" key to acknowledge that it works.

+ Now, you will be able to select the custom resolution in any modern game which would generally support said resolution, if your monitor was capable of it. Ensure VSync is OFF or you will be limited to 18 FPS (18 Hz) you set as a part of the custom resolution.

For me, I have to add the custom resolution both via CRU as well as set it in the NVidia control panel for it to work.

This adds an entire new dimension to VR - I firmly believe that its not the resolution of modern VR displays that is bad, but this rendering resolution is set too low on them.

You might also want to set higher supersampling in your VR kit - on my Rift, I usually set 1.7 - but this has no discernible bearing in VorpX at least.
