Performance Issues with the new Pimax Play SW

[Justin1Ntime]

I upgraded to the latest version of Pimax SW and noticed a considerable hit on my FPS. I have an OG crystal. In the new SW under the DFR section when I set the RR to 100% in the gaze section and 5% in the prereferral section my FPS settles in at 55. If I downgrade my SW 1.39 or 1.40 and I use Mbucchas QV and the QV companion tool and turn off QV in the Pimax SW, I can crank my RR up to 200% and maintain a nice 72FPS. What am I doing wrong? I have not adjusted any other settings other than the DFR settings between the old SW and the new SW.

Probably nothing. Im new to the whole DFR and pimax thing. Ive found all versions to have some serious issue. I cant get consistent results from anything yet and I cant figure out how to replicate or reproduce problems or stop them lol. with PP latest 1.41.2 I did get it to run at 75 to 90 fps several times but its also crashing still and sometimes will revert back to running at only 35fps. It all seems highly correlated to mbucchas quadviews its complex... lots of combos.

I didn't change anything in the settings, but now the pimax speed is a disaster. It's become really cr@p. It's playable now that I've lowered the frame rate from 90 to 72 and significantly lowered the graphics in DCS.

I'd stick with mbucchia's quadviews for now until Pimax optimizes its own implementation. Didn't notice any hit in performance in my OG Crystal with latest PP + Pimax OpenXR + mbucchia's quadviews.
