Wrong virtual display size with different resolutions

[huy-hng]

Game Tested: Hades

When changing the resolution to something that is lower than the native resolution of the xr glasses (viture pro in my case) then all modes except VR-lite result in the display being too small.

I assume this is game independent, therefore reproduction steps are as follows:

1. Set in game resolution to something lower than the native glasses resolution

2. Set mode to either virtual display or follow (the latter should have smooth follow enabled)

It's not really a bug. The screen is actually smaller when it's lower resolution. You can zoom it in from the plugin controls. I would rather the user explicitly choose to do this than do it automatically, because there's an impact to the decision to fit the display to the XR glasses resolution that I don't want to assume the user is okay with (namely that it's a lower resolution image and will be a bit blurry when zoomed in).

So your options are:

1. Zoom it in
2. Have it use the native glasses' resolution either in the game settings or by using one of the scaling options in the performance sidebar (e.g. FSR).

Oh I forgot to mention that it's smaller than even that.
Setting the resolution to 1080p fills out the screen as expected.
Setting it to 800p or 720p shrinks the screen to be smaller (if integer scaling is selected in the steam overlay)

If I enable the plugin the screen becomes even smaller than the 800p naturally smaller screen. This happens for any scaling mode.
One can also see some scaling artifacts in the image, which isn't there when disabling the plugin.

You can test this by lowering the in-game resolution and then switching between Follow and disabled or setting the mode to follow and toggling smooth follow.

Hope this helps!

With display distance/size sliders set to 1.0?
