    Sorry, but I don't believe that SteamVR at 100% says 1852x2056 for the orignal Vive even allowing for some distortion factor.. The %age is important as you keep quoting 150%, at least I assume that's what you mean when you say 1.5. SS levels are critical to performance.

    What does 4K have to do with anything?

      Same here, after this thread / video (thanks by the way, I guess many people like me were waiting for this !) I started a little tweaking again (including even cleaning my GPU cooler ) yesterday since I basically have the same setup as OP had (Zotac 1080 Ti, same CPU, RAM, ...).
      I also tried Process Lasso again (did that several times but it never worked out) and my performance was about 5-15fps less. So I removed it like I did so often before and DCS actually runs better somehow. My CPU times are usually about ~15ms, so I wonder why his are so bad.

      Went on PGAW yesterday with about 30 people on and had a fpsVR average of 42fps at 150% SS SteamVR on my Index (with Shadow mod).

      Initially I was willing to spent the "big" money on the 3090 but after seeing these (first) results of the 3080 this seems like an even bigger waste (especially for DCS!) than I thought. Might end up waiting on the 20GB version of the RTX 3080

            Just tune your Rig, it's not rocket science. There's no single setting to make it all better. A 1080Ti FTW3 with some added OC is sufficient for 45 - 75 FPS or better in a Reverb G1 with a great view and detail. Including MP and SP. If you're not there, you've got more tuning to do.
            (and no damn shaders mod needed)

            No, 100% SS does not mean exact resolution. Programatic warping is added to fit the lens optics.

              On the Reverb - and I'm sure the Index as well IIRC - 100% does pretty much mean exact res. Not so on other mostly older HMDs.

                    (Basically it allows cockpit shadows and shadows around your plane, like on the ground but removes mostly all other shadows)

                        after i read all of this ... it appears the real bottle neck is DCS 3D engine.

                        tha is very much disappointing as i also wanted to upgrade my gfx card from 1080ti to a 3080 or even a 3090 to get better fps in VR (Pimax) ...

                        that is really sad

                          whilst the engine is an issue... if you look at the OP's original post they are getting 80-90FPS, over ground in VR on pretty high settings ... that's pretty good

                            This is a very typical result for me with a Reverb. My CPU times are almost double my GPU times. And I often see 45fps, sometimes a bit more, or less.

                              Your cpu times are between 2 and 3 times mine for the same processor

                                how do cpu and gpu frametimes interact?

                                  generally speaking your frame rate is inhibited by the lower of the 2... to achieve 90fps you need both to be below 11.1ms

                                  made slightly more complex by motion vectoring/smoothing which gives you a very smooth 45 fps (it feels like 90 but with a bit of lag) if you can keep it under 22.2ms for the GPU, providing your CPU can keep up . however if your CPU is over 11.1ms there is no similar "coping mechanism" for the CPU ... which means you get erratic frame rates, and juddering performance etc...

                                    Yeah its odd, I'm wondering what is going on there in that case, though if your frame times are like under 10ms your FPS must be 90?

                                    I'm using fairly modest settings for VR similar or a bit lower than yours aside from trees and grass, I actually dropped them recently for syria without much improvement. Both for DCS settings like shadows/water/pre-load and vis. And then I took SteamSS to basically native res. My Nvida settings were a bit different and I changed them to your specs, but it seems like those would effect the GPU not CPU.

                                    TBH even at 45 it looks smooth for me, even in the 30's is "ok".

                                    The only thing I can think of is the recent MS update which "seemed" like it did something to eat frames, or one of the recent SteamVr updates but thats all I got. I wasn't using FPSVR prior to that, so I'm not sure if my CPU times were all that much better prior.

                                      no because i am GPU limited ... 1080ti

                                      check you idle cpu times, im running at between 2 and 3% ... one of the bugger culprits was iCue but there are others

                                      then make sure that exports.lua is not full of stuff you don't need etc... if have exports for VoiceAttack and for Tac view and nothing else.

                                      autoexec has no_device_hotplug = true

                                      i would normally recommend turning of HT but as you have the same proc that's definitely not your problem.

                                      You might want to check out your CPU thermals ... in case its throttling

                                      just some thoughts

                                        Can I just say that you don't need to worry about having your PC set up correctly - it's child's play to set up a PC these days. I did the VR runaround when I first got my Reverb, and realised that the vast majority of suggestions are placebo. Note that I come from a benchmarking background, which I made a career out for 20 years. Not boasting, just saying I know how to set up and test hardware of all kinds.

                                        The fact is that DCS is CPU limited in situations with complex scenery, lots of shadows, more AI, and other units. I don't think there is a fix for this until we see 7GHz CPUs, as ED is not going to be able to deliver a Vulkan port for many years. Even when they do, it does not guarantee more than a 10% increase.

                                          Whoa there? Where did you get this from?

                                          If it's only a 10% increase - that doesn't seem to be a lot for hanging on the edge of our seats for, nor something worth investing years of development into.

                                          Are you're saying someone getting 45fps could only hope to get 50fps on the same setup going to Vulcan after all that effort and work by ED (and the waiting for us)?
