Please note that I fly in VR so ymmv. I tried a bunch with the goal of finding the lowest cap value that provides a good experience. It changes over time. With SU5 I was at 30, by SU7 I needed 34, and now I’m liking 36. So it’s just personal preference. But I want it low and I perform my tests with high (not ultra) settings and at 100 TLOD. Then once I find the cap value then I adjust the settings and TLOD up slowly while watching how the change affects my chart.
If you can find acceptable settings while keeping the blue measurements above 90% and the red color as just a sliver at the end, then I think you’ll be really happy with the performance.
