Well I won't create a new topic since it looks like I'm not the only one having sluttering issues (not microsluttering in my case though). I run the game with very good and steady FPS (around 60) but each 10-15 sec I got a good 20 fps drop for 0.5 second freezing the image.
I tried pretty much everything (fullscreen mode, lowering settings, disabling hot plugs device, Freesynch on / off, V synch on / off, switching to Studio dirvers (Nvidia) but nothing solved the problem...no matter which plane I use I got those nasty slutters and the gaming experience is far form enjoyable...
DCS is installed on a SSD hard drive, got 32 gb ram, RTX2060 and AMD Ryzen 7 3700X. Using head tracking.
It's the only game where I experience slutters.
I didn't had those slutters when I started playing DCS a year back but stopped to play for 4-5 months and upgraded my PC in the meanwhile and when I came back sluttering was quite obvious...
Would love to find a fix because I'm about to put the game on the shelf ...
