Condor060

So I found the fix. After another check I found a windows update that wasn't installed. After installation everything was fixed.
Go figure. Put my high resolution settings back into DCS and its running smooth. 
Hope this helps someone smarter than me. lol

Just an FYI, I'm no expert here. Just showing what I did to correct my problems. I have built a few computers and have pretty good working knowledge but DCS has always presented problems with my VR setups. 
My equipment
AMD Ryzen 9 3900XT, ROG Crosshair VIII Hero, RTX 3080ti, 32gb DDR4 G Skill running at 3600, GPU and CPU water cooled, Valve Index VR
I was experiencing 36-40 frames that would continue to use more and more GPU usage until it hit 99% and my FPS would nose dive while CPU usage was 8-15%. I found a link about my mother board that allows you to open up some channels for gaming. You will have to search for the video for your own mother board but this is the one that worked for my setup.

Once I completed those task I downloaded MSI Afterburner and went through the scan process for MSI to calculate the overclocking for my card. Took about 15 minutes and my Core clock MHz went from 0 to 120, my Mem Clock went from 0 to 80. Heres a quick vid on letting MSI overclock your card so those of us who are not comfortable in overclocking can sit back and let MSI do the task for us.

After going through those two processes I was able to go from low settings to high settings in DCS while maintaining 60 FPS without the GPU memory bottoming out. I have flown in 3 maps and the results very from 48-60. My settings and results are shown below. Just an FYI, My resolution settings for flight are 1600 X 1200 (Or something close to that). I had to set it to my screen size to grab the screen shot. 
My DCS Pixel count is set to 1.3
