September 22, 20223 yr Something seems amiss with SU10 and vsync in MSFS general settings. I'm stuck at 30 fps no matter how low I set my settings. SU9, I got 40-60 fps smooth at 4K @ 60hz refresh. I'm using the new studio driver. How do you delete the shader cache again? Maybe I should try that. Rhett 7800X3D ♣ 96 GB G.Skill Flare ♣ Gigabyte 4090 ♣ Crucial P5 Plus 2TB
September 22, 20223 yr The shader cache won't have anything to do with this Rhett. Have a look in Nvidia control panel to make sure Vsync or 1/2 refresh rate is not on in there. Sometimes things change after a driver update. If Vsync is set globally in NVCP, or on the MSFS specific setting in the NVCP game list, it will override everything you try to do - it takes precedence over everything.

I loaded up the sim again, and magically, it's now set to vsync / 100% and it's actually working. I have no words... But anyway, now I'm doing some performance testing. It's not looking good so far in DX11 mode at KDCA. I really think my hardware should handle 200 TLOD at 40+ fps, which it was doing in SU9. In SU10 it's only at 25-30. Although in fairness that wasn't at DCA but at a rural location in West Virginia. Still, I may need to clear the shader cache after all. If I can find that location.

September 23, 20223 yr Author DX12 mode is looking good and performing well on my hardware. Under DX12, as soon as I locked vsync at 50% the panning smoothness improved quite a bit. Now I plan to turn off the frame rate counter, smoothness is all I want, anyway. I just had it on for testing to see where my hardware maxxed out at various settings.
