I see many suggestions for using CAS recently. I remember a few months ago when VR was fresh on the scene we only had NIS vs FSR (many of us used upscaling at the time). The community seemed split between both. I think more recently CAS has made its way on the scene. I’ve seen many guides suggesting that you use it as the sharpening method in OpenXR + DLSS.
I’ve done this and it’s not bad at all - but in my personal experience, NIS and FSR give a slightly sharper image, and more recently, NIS has given me sharper displays when using DLSS. (I should specify that I’m not using the scaling features of NIS, just the sharpening features)
What am I missing by using NIS in OpenXR vs CAS/FSR?
