Huge thanks. It was the launcher. Just got back my butter smooth frame times. Thanks for helping me out.

Thanks. Good point. I will try it with disabled launcher. By the way earlier it didn’t cause any issues but it worth a try.. Fps drops are clearly not performance issues, as I mentioned I have the same fps drops and frame time issues in main menu without any 3d rendering. Even the fps counter graph freezes for ~1/10sec in every 2-3 sec periodically when the fos drop occurs. Without the errors I have rock stable 80 fps and perfect frame times both in menu and during flight. Tomorrow I will try turn off the launcher and we will see. Thanks for your reply!

cef_log.logdcs.logHere are the log files, the dcs.log seems okayish the mentioned Vulkan Api errors are in the cef.log file. Hope that helps to figure out the cause. Additional info (small but probably important that the fps drop constantly occurs in VR even in main menu.

Loaded the game after updated to last version 2.9.9.2474 from 2.9.9.2406 loaded the same weapon practice on Nevada for A10C II (instant action). Until this last update my VR fps was just phenomenal. Rock stable 80 fps with close to maxed out setting. Now after the update it drops from 80 to 20 in every 2-3 secs causin extreme stutter. To validate it isn’t my config/driver/oculus rolled back to 2.9.9.2406 and again, rock stable 80 fps. Watched the log files and there is a log called cef_log.log filled with the same log error points to libANGLE\renderer\vulkan\Renderer.Vk.cpp, initialize:1378 My config is 5800x3d, 64 gb ddr4, 4070ti iChill 3x, Oculus Rifts, nvme 3.0 for win and 4.0 for dcs. please let me know if you would like to get the log file or in case you need any additional info.
