It’s weird if you use the same OpenXR settings of 100% MSFS is more blurry.
Possibly it’s because the MSFS post-processing is more heavy in MSFS (haze in the distance, AO, Bloom, etc.).
Could you share your graphics in game settings including RenderScale?
E.g. If I keep all at 1:1, render in my native resolution (CV1 screen is 1080x1200 per eye), I have very blurry results:
TAA 100%
PixelDensity (SuperSampling) 1.0
Resolution rendered by the game 1344x1600 per eye
Final Resolution send to headset 1344x1600 per eye
If I play with Pixel Density and RenderScale I have a very crisp image and still good fps (45 locked no retropro):
TAA 70%
PixelDensity (SuperSampling) 1.7
Resolution rendered by the game 1590x1892 per eye
Final Resolution send to headset 2272x2704 per eye
So it’s an equilibrium game
