I’ve disabled Tex. SS for now because in previous versions I believed this was one important factor to fps degradations at airports, especially large ones with lots of markings on the ground. This is why I’m using Aniso 16x for now in order to compensate, and except the RWY center line, usually it is still bearable with the Index resolution.
Otherwise after many tests in earlier VR versions, the best setting I’ve found back then (visuals and perf) was Aniso 8x and Tex. SS 4x4. I’ve not really tried it yet with SU5!
