The book "Luftwaffe Fighter Aces" by Mike Spick (available free here) contains this excerpt British test pilot Eric Brown, on flying a captured FW 190 A-4 (emphasis mine): This is different from the behavior I find in DCS where the stall comes with plenty of warning in the form of shaking. This happens for me in both low-speed and high-speed/high-G stalls. If anything it's the Mustang in DCS that has a sudden (high-G) stall without warning. So why the difference? Is this an inaccuracy of the flight model or maybe a difference between the A-4 and A-8 variants? I do notice that Wikipedia states that "A structurally redesigned and lighter wing was introduced" as of the A-6 variant so maybe this wing also had a different profile that changed the stalling behavior?

HAAAAAAAAAAAAAAAAAAAAAAAAAA HAH LOL Turn off vsync. FPS steady and silky smooth 40. 80 in the menu system.

Are you using VR too with that 6700k? What GPU? Yeah I turned PD down to 1.0. The oculus reprojection should cap me at 40 FPS IIUC. I'm almost wondering if the fact that my main display is a TV is somehow capping me to 30...

Resurrecting this because I actually did try OCing. I'm really confused. Got it up to 5 GHz (from about 4.1) and my framerate was still stuck at 30 fps. Even in the menu system where my GPU sits at 20% utilization and my RAM utilization is only 5 GB out of 16 GB. Why won't my framerate go any higher? Temperatures were all fine I was monitoring them.

Well I tried PD of 1.0 and I still had 30 FPS on the runway but now I had 30 FPS in the combat area too! More jaggies but it's playable for me. Thanks for the pointers! With this setting my GPU utilization is at about 50%. I'm confused by that but maybe it's because of RAM as a couple people have suggested. My RAM utilization is at about 75%. Thanks for those details Headwarp. I'm sure I could figure out OCing but I'm not sure I want to spend the time on it. I think I'm just going to build a new rig but at least in the meantime I have something playable. I'm thinking RTX 30XX something and 10700k unless the new stuff from AMD turns out to have better single threaded performance. I'll probably start another thread before to finalize my build. Currently I'm building a chair to be part of my eventual new VR cockpit!

Thanks! So what you're both saying is my CPU is fine and my GPU is the bottleneck right? But I'm confused by this because task manager shows GPU utilization at around 50-60%. Doesn't that indicate that the GPU is keeping up? I don't have the steam version and I'm not using SteamVR. Will FPS VR work? Knowing CPU and GPU frame time sounds really useful. Is it easy/possible to switch if I didn't buy the steam version? I'll try lowering PD to 1.0 to see if that helps.

I just want to make sure I'm not missing something here. I'm flying P-51D mission "Alamo". I have a 1060 6GB and 16 GB RAM at 3000 MHz. Using Oculus Rift S. On the runway I'm getting about 30 FPS (as reported by the ctrl-alt-pause overlay). When I get to the combat area this drops to around 20 FPS. Running essentially minimum graphics settings except PD is at 1.5. My temperatures are all fine. GPU is at about 80-90% utilization on the runway but then around 50-60% in the combat area. RAM and VRAM usage both look fine to me (I'd say <75% usage, GPU shared RAM is empty and I've tried disabling paging file). All six cores are underutilized (like 30-40%) because the main thread gets moved between cores. But when I set DCS core affinity in the task manager to just two cores, both were at more like 75%. This game is mostly single-threaded (or so I read on this forum) so it seems to me like I'm bottlenecked on that thread. I recently realized my mobo enabled Turbo Boost by default (or at least, I don't remember turning it on) so under load it's actually running a little over 4 GHz according to Task Manager. So, am I CPU bottlenecked? Or is there something else wrong with my system? This seems strange because according to the PassMark single threaded benchmarks the near-top-of-the-line 10700k is actually only about 15% faster than my CPU, which should get me from 20 FPS to ... 22 FPS. That's still unplayable in VR. IIUC with Rift S I should be looking to reach 40 FPS. Is that correct? I'm considering building a new system but I want to make sure I first understand the shortcomings of my current system and know what to expect from the new one.
