    But DCS fires up 50-64 software threads. All of which runs on one core (maybe two, I'm told the audio portion runs on a separate core). And resource meter bears this out.

    But again, I understand the complexity of getting the scheduling right for multiple threads to coordinate. I'm afraid when I took Operating Systems, multi-threading wasn't de rigueur! So I have no way of judging what amount of effort it takes to move the software threads to separate physical cores.
    It's not that all threads run on the same core, the operating system will see to that, it's that almost all the important work is done on only one thread.

    Think of it this way; a supermarket has 50-64 cash registers, each with a queue, (threads) and 8 cashiers (cores). The cashiers run between the cash registers to serve any arriving customers. Do the number of cash registers or cashiers matter much when there is a guy with an Eagle Dynamics t-shirt that directs 99 % of the customers to the same cash register?

    The answer is no. Only one cashier at a time will be able to do any meaningful amount of work while the others update their Tinder profiles on their phones.

    It's directing the customers (the work to be done) to different cash registers (threads) that is hard, because it turns out it's black friday and they're all trying to buy the same TV.

      I get you, just thought it might be worth checking out. The nVidia default fan curves favor lower decibel operation as opposed to performance.

        I wonder how many players complaining about DCS being an issue are aware of the limitation of their own PCs?

        I just checked on the setting of one and I find this:

        Your graphic card is too weak for this processor on 2160p/4K resolution

        Average bottleneck percentage:

        6.54% at 1080p

        8.54% at 1440P

        10.09% at 2160p/4K.

        Two thing: First I will not commit to Nvidia "new" generation of GPU, there is little new in the technology but a huge increase in size and power use.

        Second, Instead of trying to squeeze more performance out of a system by buying new gear, I'm focused in fine tuning what I already have.

        Meaning before buying anything, reducing the bottleneck to a minimum at the resolution I'm planning to use it, that would be 7.57% at 2160P/ 4K with the GPU O.C at 105%. This in view of playing DCS in VR with the HP Reverb G2.

        The Ryzen 5 3500X work well with DCS, the weak point here is my 1080 Ti 11GB which is no slouch itself so since I've got it second hand at relatively low cost, it's gonna be the subject of my next upgrade.

        That's not going to be Nvidia.

          @Thinder, similar place here. R5 3600, GTX 1080 (non Ti).
          There's a small part of me that wants to get a GTX 1080ti and Reverb G2, but I think I'm going to keep saving for a little bit longer, and see what happens over the next year, both Headset wise and graphics card wise.

            Right now, I'm limited by the CV1 and I can't really tell if the 1080Ti is capable of handling the G2.

            I'll make my decision once I got the G2 and by then, the new generation of AMD GPU will be out, when I upgrade I'll base my choice on the best bound for the R5 3600X.

            If it's not done already, try playing around a little with Ryzen Master, there are Game modes and Auto Overclocking modes that makes it easier and safe to fine tune your system.

            Simplest setting: 4,500MHz Maximum.

              I run the g1 reverb on a 1080ti my settings are below. A lot will depend on your cpu frame times but I get acceptable, by no means perfect,m performance on a 1080ti The g1 and g2 drive the same number of pixels and so you will get similar performance.

                That's good news, thanks!

                At the moment I run tests after tests (3D Mark and Heaven Benchmarks) to figure the optimum settings for my 1080 Ti, the 3600X is sorted.

                  What are you guys doing running steam supersampling @ only 150% with a 3080 ?

                  You're not going to see much of a difference indeed like that.

                  Put that slider on 300% , textures high, visibility extreme, Msaa on .

                  Then test with your 1080 ti first, and then with the 3080.

                  edit* I can see that in multiplayer or missions with A.I the performance gain will be a lot less. Holy crap just getting into a very simple multiplayer pvp mission with not a lot of A.I at all will put SO much load on only 1 core. It's a little sad actually

                    This has always been the concern, the results depend a lot upon what you like to use DCS for. Free flight, AI furballs and multiplayer will have very different outcomes depending on just how much the CPU is stretched.

                    Of course there is nothing wrong with having the best hardware and there will always be gains to be made but I think we just need to manage expectations.

                      It's in! MSI gaming trio 3080 card came in this morning with the Postman. At last. So time to test myself. Can I do Magic? We'll see...

                      First impressions.

                      Not the ultimate solution!

                      yes, you can take dcs settings little further like MSAA and distance view, full shadows.

                      But FPS is not much higher then before.

                      Statement!

                      Please ED go for another game engine that makes vr great again.

                      thanks.

                        This sound worrying when it becomes more clear the engine of DCS is at its limit.

                          Well, it will be many years before anything changes in that regard right ?
                          Haven't they quite recently overhauled the engine already ?

                            Well they are moving to Vulkan, the question is when it will be implemented.

                              Looking forward to Vulkan. DCS will be amazing once you get a steady 90fps/hz on a high resolution VR headset like the G2 reverb. At that point, who needs the real world anymore?

                                Dont get your hopes up. Vulkan might be able to give some boost in VR, but its not gonna be magic. I'd expect 25-30% improvement in VR at best. Really DCS will benefit probably the most from multicoring some "new" features as they are added in so it won't further bog down the main threads.

                                    45 for me is actually quite good. 90 would be better, of course.

                                    The promise of vulkan for me is the mgpu capability. Where maybe, SLI like function could be had for VR.

                                      I mean its been more than 2 years since they announced it, I bet its at least 1-2 more.

                                          No, the "two weeks" is a running joke.

                                          Wags announced some of the work was done for Vulkan, but that all the shaders needed to be touched.

                                          So it's probably next year the earliest? That's a SWAG on my part though.
