Hi,
My experience is very, very similar to yours in terms of my hardware and ghosting.
There are far more knowledgeable people on here to help but i ended up turning ASW off and making sure i can consistently hit 80fps without it and setting my headset to 80hz. This has removed the ghosting albeit with a small amount of graphical compromise.
MSAA X 4 and SSAA X 2 on, full res in quest 2 and 1.0 PD. Shadows seems to be a problem in 2.8 according to other forum discussions
I didn't get to see Vr performance in 2.7 but i gather it was much better so im hoping to turn the few compromises up if it gets resolved down the line.
All in all looks great now and can have a dogfight without feeling drunk.
Eagerly following this post to see if any other tips come up
90hz seemed achievable but i like eye candy so didn't want to reduce the graphics anymore
Cheers
