Glide

The main roads seem to have a concrete barrier down the middle to divide the lanes. The issue here is that placing units on the road will often leave them hung up on the barrier. Driving using Combined Arms is also very tricky. Any plans to remove the barriers?

Try dropping Grass and Clutter to zero, and maxing out the Preload Radius. Visibility to Medium would give you a big boost too.

Stutters can occur from too much mission action as much as graphics issues. For example, if all the artillery is going off just as a bunch of units are turning a corner and a full IADS is going off, and you get the picture. Make sure you test on the same mission each time you make changes, and pick one that's not busy. Stutters usually mean you are trying to put too much through the card, and it just needs to stop and restart. I see from your specs you have 2 GB of VRAM and 16 GB of RAM. I see you are running at 2k, but I would try 1440 x 900 or 1360 x 768.

You can bring Visibility Range down to HIGH or MEDIUM. Set Grass/Clutter to zero. That might give you back enough to have high shadows. I personally have them on Medium and Flat.

Looking at the cockpit textures usually brings down the FPS counter, especially in the F-16. The big question is does it stutter?

With Nvidia Fast Sync and a little tweaking of the quality settings, and I am back to running smooth at 4k. Update: I switched to MSAA, and I discovered at 4k that Anisotropic Filtering is not noticeable. I turned that off and tuned down my Preload Radius to be 3/5 of the range to match my Visib Range (High is the 3rd of 5 levels). With my hardware I don't notice a change from Preload Radius, but that seems logical to me. YMMV.

Post snips of your DCS settings and Nvidia control panel settings.

I would try cutting the resolution down as far as you can go. High resolutions like those in VR headsets require a lot of VRAM. My 1080Ti has 11GB, and I am finding that 1440x900 is optimal if I want max quality settings. Just watching a video on the G2, there's three places to set resolution, General, Video Application Settings, and Windows Mixed Reality. I would crank them all down to the lowest and make sure they match. Then I would work my way up form there.

And happily for me, I took my resolution down to 1440x900 and by scaling back the amount of graphics, I could get the ultimate holy grail of all the DCS quality settings: SSLR. So, if you have 6 or 8 GB of VRAM, try these settings at 1280x1024 or 1360x768. If you have 4GB of VRAM, try the lowest three resolutions in DCS. Happy flying.

And just to be sure I wasn't dreaming, I went dogfighting over Damascus. Given that my 1080Ti has 11GB of VRAM, if I had a card with 6 or 8 GB of VRAM I would I would try these settings at 1440 x 900. This resolution was also very nice on my "4k" monitor. TLDR, start with the lowest resolution you can tolerate then scale up the quality settings until it starts to stutter. If you can get to max settings with that resolution, bump up the resolution, and scale the quality settings again.

It turns out that as you scale down the resolution, you can upscale the quality settings. My monitor is a 16:9 ratio, so I went from 1920x1080 down to 1600x900, and I can crank up the quality and still get 60ish pfs with FAST.

After getting DCS Vsync working, I have a good sense of what my card and monitor are capable of, and then I switched to FAST vsync with SSAA and the same great smoothness but with nicer edges. Give my settings a try. Note that my 1080Ti has 11GB of vram, and I'm running my monitor at half (2k) it's native resolution. I'm going to try cutting the resolution in half to see if I can hit max settings.

I started putting these guys on the Red team, and they really spice up a dogfight.

Sorry, I don't have VR, so I might be wrong on how it affects VR, but this setting is in the Nvidia Control Panel. You also want MFAA MultiFrame AA on with MSAA, but not with SSAA.

WIN+HOME and WIN+END auto start and auto stop the aircraft by default. The Hot Start from Batumi Instant Action Mission is a nice mission to practice with the trainer. Set prop RPM to max, set 5 degrees right rudder, pull the stick back to engage steering, taxi out and gentle throttle until you feel the tail rise letting the stick come back to center as you gain speed, then gentle throttle until you are airborne without much stick input. Gear up and reset trim once you are in controlled flight. Set your prop and engine needles in the middle of the green, and have fun! I also recommend TrackIR PRO for looking around. Lots of youtube videos on getting that sorted out. Thrustmaster T.16000M combo is a popular HOTAS setup that you can find in stores. I use this myself. Setup is much easier in DCS for HOTAS. The F-16 is well documented as are quite a few of the full fidelity modules. The Viper is early access, but you will not regret sticking with it.

If you are using MSAA, make sure you set your Antialiasing - Transparancy to MultiSample. This controls the apha textures in trees and vegetation. If you are using SuperSampling, set it to match your level of Supersampling. So, if you are using Supersampling x2 in DCS, set it to 2X (supersample).
