Hi, could you please share your settings ? (pitool, steamvr and DCS), I almost have the same hardware as you (WC 2080TI@2100mhz) but very low fps in DCS solo airbase strip with F18.
What is strange is that CPU is 50%load and GPU max 80%, even with brainwarp disable.
I have a Pimax 5k+ and the clarity is really good, but with noAA or AAx2 I think it's really flickering.
Thanks for your return
