Quadviews is fantastic in DCS. It nearly doubled my frame rate. It takes up a few CPU cycles, not many - and right now I am GPU limited by a large margin on my I9 13900K with RTX 4090 in MSFS 2024. And most importantly, with Quad views in DCS everthing is crystal clear, I can even run the area my eyes are looking at at even higher than native resolution of my Pimax Crystal!
And because of the eye tracking in my Pimax Crystal I can not see the degradation of the visuals outside of my field of view. Seemed like magic when I got it working in DCS. Crystal Light users who don´t have eye tracking will still benefit from Quad Views, but I guess they might want to be a little less aggressive with its settings in the out of focus areas than people with eye tracking headsets.
