I’m working on something for that right now as a matter of fact.
It’s actually quite interesting. Right of the bat you could argue that VXGI should always beat VXAO because it actually includes the GI but I’m not so sure where it concerns a RealTime environment.
To be honest, and might come across a very bald statement, but how often do you REALLY notice good GI? I can only speak for myself but I’m always way more drawn to good quality shadowing
and occlusion. Anyways, more on subject later.
