    System VR ready?

    Hi all, a few years ago I had to quit playing DCS and sold my rudder pedals, track-ir and HOTAS etc. Now I want to go back into the game again, this time including VR. But I'm really wondering if my system specs are capable to run DCS decently in VR. Steam VR check says my system is VR ready (just at the beginning of the green bar in the test). What are your thoughts?

    I have Win 10 with:
    i5 4670K @ 3.4Ghz
    16GB ram (pretty old stuff)
    RX470 4GB videocard
    SSD's etc

    I'm willing to upgrade to a new vid card (but prefer not to), when upgrading I never go for the latest high-end stuff (usually I'm behind 2 or 3 generations).

    For VR I'm thinking about getting the Quest 2 with the Link cable to attach to PC, but now completely sure yet if that will be best bang for the buck.

    Quest 2 is best bang for the buck.
    But your system is no that VR capable: You will have to upgrade to a full new system.
    Period!

      I understand that you would like not to upgrade if you can avoid it.
      DCS is still more or less using only one core for the main thread.

      I dont know much about the radeon cards, but I guess you actually ”need” to upgrade the GPU.
      There should be a lot of used good cards on the market now when the new series of RTX is coming. From memory, Radeon wasnt really that good for VR compared to Nvidia...?

      For the other hardware stuff;
      - The 4670K is more than capable of your needs. It will force you to overclock it, you would need to hit at least 4.5Ghz, preferebly 4.7 or more.
      Done this with my sons 4670K, no probs.
      It is good for VR. Period.
      16Gb is good enough, prefereble 32Gb for complex missions but you can live with 16. No problems. My sons had 24Gb 1666mhz and after some tests we actually downsized to 16Gb, my old memories that is 2133, if I recall it. We did get better performance with faster but less.

      You would probably count with the need for a new GPU, course slide shows isnt fun. Maybe, if your computer was a mid level you might need a new PSU depending on what GPU you find.
      Also, depending on the CPU cooler quality, you might need a new with head room for overclocking.

      So it should be possible to get around the problem with not that much costs and still be able to do VR. Some minor lower graphic settings might be needed depending if you hit 4.5 or 4.8Ghz.

          My suggestion to you: You desperately need a full system upgrade. If you're smart, starting today you can start getting the items with very good discounts.



          Start looking for either a second-hand or new B450 tomahawks motherboard and don't waste a good bargain. As the most popular msi b450 motherboard, it will definitely have the optional firmware upgrade to support new zen 3 processors.

          https://www.cclonline.com/search/?q=b450+tomahawk


          Then get the new zen 3 CPU, the equivalent of the current zen 2 r5 3600 with some 32gb ddr4 3200mhz ram and I assure you that you'll be future proof for at least the next 4 years. You can also get a r5 3600 now, like mine, and you will be good for sometime while still having the possibility to upgrade to zen 3 whenever you feel the time is right. Make sure to keep the original cpu fan stored in the original box for when you're ready to put it for sale on ebay.

          In the meantime wait until the smoke clears out and all the bots and all the obsessive consumerists that camp in front of "apple" stores (nvidia resellers in this case) get their new next gen gpus and start looking for second-hand bargain previous generations GPUs, like a 5700xt, a 2070 super, or even 2080s.


          This way, you can get a very capable system, for a fraction of the full price. Me, I'm like you. I'm not the one who will spend thousands for fresh new gadgets. Instead I look for value-for-money bargains. I got my 1070ti for £120 + my b450 + r5 3600 + 16gb ddr4 ram* for less than £370! (new and shipped!) That's a less than £500 system, VR ready. I can play most VR games, in my CV1, at 90fps in mid-low, and dcs in mid-low at smooth 45fps in the syria map. My next upgrade will either be a next gen amd gpu or a previous gen rtx while keeping my CV1 until they force me to log in via facebook.



          *Recently upgraded to 32gb by stepping onto a bargain ram sale!

            Thanks all for your input so far.

            In regards to overclocking, I got a good Gelid Solutions Tranquillo (Rev. 2) cooler, so it should be capable to do that I think. However, when I bought the CPU I tried experimenting with overclocking and got a lot of problems as it's not my expertise, so didn't want to risk it, and threw the towel into the ring (as it wasn't needed at that time either).

            I've got a Seasonic Bronze 520W power supply, I'll have to look up modern power requirements of GPU's, but back in the day it was more than capable. But times change of course

            I'll definitely will research a bit on what budget I'd need if I would build a new PC from scratch (be it new or second hand).

              @Manne: Dont let anyone fool you to get a CPU that is not capable of at least 5.0Ghz if paying for other hardware. And for all its worth, dont upgrade to antything less capable when it comes to clock freq.
              Your 4670K can do at least 4.5Ghz and as DCS is like it is, DCS CPU performance is more or less all about clock frequency.

              That said; I dunno much about AMD.

              [Edit] Single core performance from a ryzen 5 3600 is only about pair with the 4670K.

                OC is not hard. New to it = check youtube and also read a little. My overclock of my sons took 5 min but then I done this since 1995. Put 10hours including youtube and reading= done.
                If money is an object, every hour spent on this is worth a lot of money, as you can make your 4670K perform like more expensive CPUs. You cannot reach values like my 9900KS@5.2 but also, you avoid using up 5-600usd on the CPU alone. Or, build a new/ used. But dont fall into the trap getting a CPU with to low single core performance.

                            I'm sorry, but I'm still waiting for your real world benchmarks that validates that your stated synthetic 8% spec performance increase R5 3600 vs 4670k translates to actual DCS only 8% performance increase. You said I'm trying to fool OP, then prove me wrong.

                              Dont wait for me on this. It not my job to convince op you have the best option for him.
                              Im still saying he should be able to use the current H/W but a better GPU and maybe a new PSU.
                              Also saying, if upgrading, be sure to get a CPU with at least a lot better single core performance than the current would give ocerclocked.

                              Im not saying he should upgrade exactly like my 9900KS@5.2, also not pay for a RTX3090 like I just did. He could. It would be a very potent DCS machine, but also very expensive.

                                Why would a higher clocked cpu be needed? Is this VR related or DCS related in general? I was thinking the gpu would be the most important, with the higher screen resolution needed for two VR viewpoints. I’d expect the CPU requirements would be the same, or is this because the minimum FPS in VR must be relatively high, thus the CPU is more important so it doesn’t dip below the required minimum FPS?

                                  There are two aspects for performance in vr, GPU frametime and CPU frametime. The GPU *is* very important but the total frame rate is limited by the highest of the CPU or GPU frametime. If the cpu frame time is 16ms and the gpu is 20ms you will be limited by the gpu, of course with the gpu you can use motion vectoring or asw to improve the perceived smoothness of the erratic frame rate of the gpu..if you upgrade the graphics card and get gpu frametime of 12, you will still be limited by your cpu in this example, you can improve your cpu frametimes by over clocking the cpu and or by upgrading the cpu.

                                    Its because DCS game engine isnt good at using your CPU total performane.
                                    It doesnt matter how many cores your CPU has - DCS vill more or less only use one core really hard instead of splitting the needed cpu power on more or all cores.
                                    In fact, it looks like DCS uses three cores/threads but two isnt stressed at all and one is very stressed.
                                    If you look at the total CPU usage in total it might look like 60%( or 13 down to 7% with a high end CPU) but if you look in the details( windows resource manager for example) you can see the load on each processor thread and you will find one core with high load and all others sleeping.
                                    When/if you reach 100% on that core your CPU causes stutter because it can not produce the work needed for each frame. Still, the total CPU load is low. DCS can not use any more of the available CPU power.

                                    The need for single core clock is around 4.5Ghz with dcs graphic settings tuned down to compensate for a slower CPU. If you get a higher clock you can increase some settings.
                                    Even the fastest CPU with 5.2 to 5.4 ghz can not do all settings maxed, so settings will need to be a compromize. Yes, you want a high CPU clock for DCS!

                                    [Edit]link to a older post from me. Look at the two lower pictures on the left side. “CPU core” no 15 close to 100% despite 5.2/5.1Ghz, and this in a instant action that does not set the CPU need very high.

I was thinking the gpu would be the most important, with the higher screen resolution needed for two VR viewpoints. I’d expect the CPU requirements would be the same, or is this because the minimum FPS in VR must be relatively high, thus the CPU is more important so it doesn’t dip below the required minimum FPS?

                                      The reason is because ED failed to keep the core game engine updated to new technologies, like multi-cored cpus, so the game uses basically one or two cores only for everything. The game is not at all optimized for VR, so in theory, higher cpu single core frequency equals higher performance. On the other hand, to base one's assumption on that alone is short-sighted, because it doesn't take into account, for example, higher ram speeds that can only be achieved in modern systems (motherboard+cpu+ram), among other things that contributes to performance other than cpu frequency alone.



                                      By the way, what's your motherboard model?

                                        If you like to show the performance of the Ryzen single core you cold use this benchmark and present the results in this thread:

                                        Need fpsvr to do. It shows how a CPU can handle DCS(mainly the single core performance)DCS.
                                        Also post the DCS settings, and what VR set you use.
