I went through this with the 2.5.6 update. It’s very easy for people to overthink the settings with all of the “it works for me” mods and setups out there. I got wrapped up into it as well. The fact is, all of our systems are different. Some things work, some things don’t. VR vs. monitor, rift s vs. odyssey+, 1080ti vs. 2080ti, 16GB ram vs. 32GB, etc. (makes me want a signature with system specs required for all members...). Your system should handle DCS.
Take a deep breath and reset. Everything will be ok.
Get rid of all mods, do a repair, erase contents of metashaders and fox in your saved games folders, reset entire Nvidia CP to application controlled, and start with DCS settings at medium. Test. If things are good, start bumping up the settings. Here’s the important and time consuming part, but so worth it. Adjust settings one at a time, maybe two. Easy to go crazy and lose track of changes.
I did that and got to max DCS setting, MSAA @ 4, SSAA @ 1.5, PD 1.2 and v-sync on running 40-80 FPS depending on what I’m doing. I personally think 40 FPS at high settings runs/looks better than 80 FPS on medium settings. Super clean and “smooth enough.” Trying to be perfect will only frustrate you.
Good luck!
