You'll be sacrificing image quality somewhere. The question is just how much. It'll also depend on your resolution, higher base resolution means more for the algorithm to work with. So high fidelity HMDs like the VP2 or 8k X benefit more than something like the Index does. I still wish people would include it as an option. DLSS looks better than FSR 1.0 in VR by a good degree, 2.0 would be awesome.

Personally, I found the VRPerf toolkits FFR feature a god send on Pimax, since it blurs the outer radius for some sizable performance gains, and the parts in your peripheral and outside the sweetspot are a little blurry anyway, so it's not that noticable.
