I also had this stuttery problem when flying over big cities like London, or Paris at low altitude, when I look down. Following your message, I tried to disable ASW with the Oculus CV1. The stuttery is hardly present anymore.
Until now, despite an OC of my RX 6800 XT @ 2650mhz I had been disappointed with its performance.
Yesterday I set the minimum to 2550mhz and the maximum to 2650mhz. I went from 22.5 fps with drops to 19.6 fps on the TBM 930 over London to ~ 30 fps.
With an A320 taking off from KJFK I went from 11.2 fps to 22.5 even increasing the resolution scale to 150%
I am all in Ultra to do his tests.
I think the ASW of the Oculus duplicates an ASW from AMD or MSFS, because even if I turn off the ASW of the Oculus I still have the 45 fps step when it can’t displayed 90 fps and 22.5 fps when it cannot display 45 fps. It can even display 11.2 when it cannot display 22.5. Now it is certain that at 11.2 fps it is not playable.
@ATCCM There was a tire advertisement with the slogan “Without control, power is nothing”
We can not deny that these RX 6800 XT does not lack power, now we just have to hope that AMD comes out of the drivers for us to master this raw power.
I wanted to send it back to the merchant, but when I saw the unavailability of RTX 3080 and the prices of the RTX 3090 I decided to keep it and hope for improvements on the AMD and Asobo side.
EDIT: I just relaunched MSFS without having the OC of the RX 6800 XT I have the same performance.
I realize that I spent at least 90% of the flight time testing with this game …
