I'd like to give a little experience report on my development since updating to 2.7. Hope, it's useful.
My configuration:
AMD Ryzen 9 5950x, ROG Crosshair X570 VIII Hero, AMD RX6800XT, 64GB DDR4-3600, Hotas TM Warthog, HP reverb G2, 1 Display 3440x1440
steamVR 120% (application setting) and 100% general setting. No motion vectoring. DCS PD 1.0 and textures to high, msaa 2x, ssaa 1,5x...
Before the update, I had fps of in average between 40 and 60 in VR and between 90 and 110 in 2D.
After the first update, I experienced a severe fps-drop both in VR and 2D, especially testing in the free-flight-scenario on the syria map. Landing on the first airport there let the fps in VR drop to average 15 in VR! It was almost a slideshow and I started to sequencially follow all the tips and tricks mentioned above:
- renamed the DCS openbeta folder in saved games
- reinstalled DCS completely
- repaired windows 10 installation completely but no uninstall of the KB500????
- Updated AMD Radeon software to 21.4.1
After these steps the situation became better again, almost where it was before, but I cannot say, which step really was the key.
But then I also followed Spudknockers advise to turn off most of the settings for the graphic card. Though he said this for an NVIDIA setting, I tried this for my RX6800XT and it had a really positive effect! I literally turned off everything or left it to the application, also the AMD FREE SYNC. No OC either! Just the basic driver, so to say...
And:
No micro stuttering anymore, stable fps of >40 to 60 fps in VR in every situation with really high settings! Also tested on some MP servers and it was really good!
So, I'm really happy now with the performance!
I have to mention, that in VR for me the new clouds don't look any different between low and ultra settings, so I kept it at low for now.
