Performance difference with OpenXR / Internal render scaling

[MrFuzzy 2,118]

Hello,

FYI I noticed that when I use OpenXR render scaling I obtain almost 20% worse performances without any perceivable graphics quality benefit.

I.e. in the same conditions (a flight started over Milan with default settings and C172 G1000, clear sky):

- OpenXR 70% - In sim 100%: 33 fps

- OpenXR 100% - In sim 70%: 40 fps

yeah I'm the same. It's unfortunate that the cockpit gauges lose clarity when in game render scaling goes below 100

It seems you don't get something for nothing.  I tried it and there is a very perceivable difference in visual quality between the two...at !east with my G2 and Sim settings?

I don't know how I managed to keep every scaler at 100%, decent middle-ish settings, full lod and still get 30 fps with my setup, I'm keeping my breath, anything could ruin this balance.

I run scale at 100 in both sim and openXR. Pretty high settings too. Using 3090. Seems to work ok for me. In GA and in airliners.

Very perceivable difference in quality to me.  You don't get something for nothing I'm afraid

Not surprised with a 3090.

Same for me, fluid with these settings . And I also have a 3090. That seems logical.

But:

Today I tried with 100%TAA and 70% OXR and motion reprojection ON and that results in WORSE performance ( I assumed better performance but worse graphics): FS does I would not call it stutter, but kind of fluid movement and every half second a tiny shift of the image of the scenery (stuttering for me is: a set of these tiny shifts directly after each other , something like as if making this sound equivalent pu-pu-pu-pu-pu , instead of bzzzzzzz pu bzzzzzzzzzzzzzz pu (bzz then represents fluid motion). I can not explain better.

I test on ORBX Wycomb Airpark and native KSEA. CJ4 and JF Piper Arrow.

BTW I have HAGS ON, 465.89 driver and Windows 10 21H1 update. I9 10900K (I thought I updated my signature).
