Here's my first flight from yesterday for anyone interested. Flew the Hornet and the Huey. My impressions were "mixed" if I'm honest. I spent a couple of hours in cockpit just flying around taking in the terrain. The video below is edited down to 25 minutes of that experience. Chapters are included so you can skip to spots I felt were worth calling out. My favorite part of the video starts at the 12 minute mark where I discover Bodo in the Hornet. VR performance is "okay". If I let myself get immersed, I don't notice anything that breaks the immersion. If I look for the studders, I see them. For me, I can live with this. Helo flight starts at the 17:15 mark of the video. The fact they haven't even tested VR (stated in Social Media) floors me. I am amazed it runs this well with no attention to VR from the devs. Highpoint: Bodo Terrain in the Hornet (12:00 mark of video) Lowpoint: 2 CTDs (DCS completely stopped executing and was killed). First captured at 3:40 of video coming from F10 map to F1 cockpit in Hornet.

Input on a moderate system that may help others without the big pockets needed for a RTX 4090 GPU. System: i5-12400F (Overclocked to base 4GHz, manually set to all cores, turbo mode off) RTX 3070 (Overclocked GPU 2115Mhz (+200MHz), VRAM overclocked to 8Ghz (+1000 MHz) 32GB DDR4 RAM Pimax 8K+ (No base stations, 9-axis) MSI Z690 Pro WiFi DDR4 Motherboard Results: Syria map, heavy mission with high load of aircraft, vehicles, and static objects Cockpit view (A-4 Skyhawk) - 43-51FPS (Lower values only momentary. Majority of time is 48-50FPS) External view (F2) - 36-51FPS (HIGHLY dependent on what one is looking at. Planes in flight upper numbers. Helos on ground or aircraft taxiing lower range FPS) Vehicle view (F7) - 35-53FPS (HIGHLY dependent on what is going on in the view. Simple vehicles/static objects, no problem. Combine moving vehicles, explosions, firing, flames, aircraft flying overhead and the frame rate hits the lower end occasionally.) NVidia Settings: Image scaling - Off Anisotropic filtering - App controlled (***Make sure you have only one program doing this function. It is easy to slip up and have several programs selected to do the same thing!***) Antialiasing - FXAA - Off Antialiasing mode - App controlled CUDA- GPUs - All Max frame rate - Off MFAA - Off Texture filters (in order) - Off/Allow/High performance/On Threaded optimization - On Triple buffering - Off Vertical sync - Off VR pre-rendered frames - 1 OpenComposite settings OpenXR OXRMR settings: Rendering custom scale - 115% (***Make sure you have only one program doing this function. It is easy to slip up and have several programs selected to do the same thing!***) Motion reprojection - Disabled Pimax settings: 72Hz FOV - Normal Render quality - Custom 1 Fixed foveated rendering - Balanced Parallel Projection selected OpenXR toolkit: Upscaling/sharpening - CAS Sharpening - 50% Fixed Foveated Rendering - Off (***Make sure you have only one program doing this function. It is easy to slip up and have several programs selected to do the same thing!***) Turbo mode - On Post processing - On DCS settings (off unless otherwise listed): Textures - Medium (cannot see more detail at high setting) Terrain - High Water - Med Visibility range - Med Shadows - Med Res cockpit - 1024 (really cannot tell difference between this and 512) MSAA - 4X (GREATLY reduces shimmering in headset. I have tried all combinations of rendering levels in DSC/Pimax/OpenXR, SSAA, MSAA. For whatever reason, this seems to work best on my system. ***Make sure you have only one program doing this function. It is easy to slip up and have several programs selected to do the same thing!***) Clouds - Low Clutter/grass - 500 Forrest Vis - 50% (Syria map has WAY more trees that the Golan Heights has in reality. I turned this down just to make it more realistic. Higher settings do not seem to impact FPS. Literature indicates the trees are actually still there at lower settings but not rendered to the screen) Forrest details - 1 Scenery details - 1 Preload radius - 100 Chimney smoke - 1 Anisoptrophic filtering - 8x (***Make sure you have only one program doing this function. It is easy to slip up and have several programs selected to do the same thing!***) Terrain object shadows - Flat Rain droplets - On VR density - 1.0 Force IPD distance 40 (I flew the A-4 in real life. Setting this to 40 gives my eyes the same perspective I had in the actual cockpit. Your mileage may vary) I have spent many hours working all the settings. Much of what goes into making DCS perform at its best is FM (Freakin' Magic) and pure trial and error. Take my inputs with a grain of salt. I hope these give you at least a good place to start from.
