Single Pass Stereo implementation
Where did this option come from? Was it available in vanilla Assetto Corsa or added in Content Manager? Can't find any mention of it in the code. It adds a significant performance boost in AC+CM so I've been looking into the possibility of enabling SPS in Unreal Engine 4/5 games using UEVR by adding this to the game's Engine.ini

*Apparently ACC uses it?
Here's how it looks in The Callisto Protocol.
But performance didn't improve, many objects are rendered incorrectly (each view seems to be a half of a 2D image), shader effects like shadows seem broken which might require fixing/recompiling and the UEVR dev said:
As per the settings menu you are in, SPS is included as part of Custom Shaders Patch.
