Gunnars Driver

I upgraded my computer last cristmas, not because it needed to but because I had the money and has the technical interrest. What I had was an i7 3770K. Bought early 2013. Thats the precursor of your 4XX0K. Mine was an i7 but for DCS that part isnt important as there is no need for many threads(remember, DCS only use a couple of threads). I got into VR 2016 when Oculus rift came up. Only changed the GPU to a VR-ready one(GTX1080) and then it worked fine with DCS. No problems. Your 4670K can be overclocked and used if you would like to. Its your decision, to OC or to get new hardware. Buying new hardware that really make a big difference in the CPU case comes with a cost, compared to a overclocked 4670K. If overclocking is not an option then you should get new hardware.

If you like to show the performance of the Ryzen single core you cold use this benchmark and present the results in this thread: https://forums.eagle.ru/showthread.php?t=287061 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.

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. https://forums.eagle.ru/showpost.php?p=4230368&postcount=44

I recently ordered 8KX and base stations. I havent really got a grip of the controllers. Pimax own is not out yet... Which controllers can I use with the Pimax and which one is recommended ? (Starting to feel I might have done a misstake, not ordering the knuckles togheter with the pimax...)

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.

Of course. Its not me you should help, its op. Dont take my former post as a ill ment hit for you, it was ment as a help for op not to get a CPU that doesnt perform as much better as the money spent, in the eyes of the op. Go ahead! :thumbup:

Ryzen 3 3300X only gives 8% more single core performance to a OC 4.5ghz 4670K at 4.7 the difference is even smaller.(comparing non OC zen 3 to OC 4670K) This to show OP that overclock of current hardware can be a alternative to spending $, or €, which I understand might be the OP wish if possible. https://cpu.userbenchmark.com/Compare/Intel-Core-i5-4670K-vs-AMD-Ryzen-3-3300X/1538vs4076

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.

@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.

Yes, we had this discussion in another thread the other week but there was different ideas about this. My experience is about the same as yours, and I have found myself needing to lower settings a bit when I hade VRAM usage( or allocation) close to the physical limit of 11Gb and got a little stutter from what I at least thought was due to Physical VRAM limit. I tried SS between 150 and 200 and found it sharpening the picture(= cockpit instruments) more the higher the SS, byt my OC:d 2080ti only had the power enough for SS150 to keep the smooth gaming that I personally needs to enjoy. I dont have the slightest concern that the 3090 will add the headroom I would like

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.

Yes, exactly. Quite small improvement per buck. If cost is not an issue, get the best, highest clocking CPU. If cost is, use the money on some other performance inceasing part and get more gain per buck.

I was a bit sceptical about WMR comming from Oculus Rift. I have only used the reverb for DCS and asetto corsa but for this, I have no problem at all with the WMR-thing. The headtracking has been a littla problematic. Initially I could fix it by havbe full light in the room but after the summer the tracking is not good despite full lighting, four lamps in the room, only played DCS so I dont know if its the reverb/WMR or DCS causing this. Dont except to be able to game in a dark room with inside out tracking.

I found a difference of about 200 Mb, not important for tuning or deciding. Anyway: 1Gb is 1024 Mb so 7.7 = 7884 Mb. Not a big diff, actually about the same I have seen. I would guess GPU-Z is more correct. Probably it is the same with VRAM as frame times in fpsvr: only counting the usage direct coupled to the game.

Thats one of the reasons, but not the only, which made me choose 3090 over the 3080.

Might be, but 22fps is a slide show. With low settings and proper working 7700K + 2080ti + 32Gb it shouldnt really ever get down to 22fps.

How is the reverb / setup done? I think following the guide from vr4dcs could be smart. ( https://vr4dcs.com/2019/08/08/moving-from-oculus-to-reverb/ ) I think its updated enough to get the big picture when it comes to the initial setup. PD should be 1.0 in dcs and if higher resolution is desired( it gives a sharper picture) the oversampling should be done in steamVR instead. For the settings in dcs, brb with some links later.

Have you verified that the hardware run as it should? A good way is to use for example 3D mark and check that the hardware delivers the expected points for your CPU and GPU. One other thing: you cannot look at the CPU load for the whole CPU fir DCS. DCS mainly loads one core hard and another just a little, all other cores is more or less not used. This causes the total combined load to look as low( 10-20% for me, and probably 50% for you). But one core may be overloaded and struggle hard anyway. If that core is loaded to 100% the rest of the unused cores cannot help and the gamestutters despite “CPU load seems to be 50%”. You can see the load from the task manager —> performance—> resource manager(or name close to this) and select CPU. Make sure all cores is seen and try DCS and then look in the grafs. Probably one core is hitting 100%

We need to cool down the horses! GunslingerAUS seems to be a lot more sensitive than the average VR-gamer. (No offence, Gunslinger? we have discussed this before). Gunslinger is sensitibe to the motion reprojection. I am sensitive to normal gaming stutter and cant enjoy movies ahown in wrong fps( causes non smooth gaming). I have no problem with the Reverb and RTX2080ti at all. I did use the Oculus Rift CV1 during three years before I got the Reverb and the Oculus ASW was not as good as Reverb Motion Reprojection, ASW caused qiute much ghosting/double pictures not in the correct place. Reverb/Motion reprojection does very selldom produce any ghosting. Actually, for me I dont notice the difference between 90 fps and 45 fps with motion reprojection that easy. As long as 45 fps is kept without stutter. I think I use slighly lower settings(Supersampling for example) than some others on this forum, I tune the settings to never( at 99.9% of time at least) not have any single stutter at all. I did hang on the trigger for a Asus 3090 Strix OC, but not because I absolutely need it but because I can afford it and it will be a good extra VR-power when I get the Pimax 8KX. So, Gunslinger is not wrong, but his experiences might not be shared by the most others. I have followed Gunslingers case with a lot of efforts to be able to enjoy VR. Actually it feels a bit sad because I think Gunslinger has made such efforts that he had earned the right to finally enjoy VR, and if the 3090 didnt solve the issue, I guess it might be some time further without a solution :-/ And of course, thanks Gunslinger for the 3090 report! :-)

Yes! All test available tell us that. I’m not worried at all that it will be a good upgrade.

Saw this yesterday, 2080ti and 3090 in test.

Not for me( 1440P screen, settings maxed out). Most of the time the indicator in developer mode says limited by GPU. Some times it says limited by main thread and some times is alternernating between the two. Also, can keep 60fps quite much. My friend with a 10980XE +2080ti +4k screen do not either allways say limited by main thread. 4K settings tuned down from highest to keep 60fps mostly.

Mainly harder on CPU than DCS is. With my settings, the CPU more or less never limits in DCS. In FS2020 it depends and varys between ”main thread”(=CPU) and GPU. Most times it changes multiple times per second between GPU and CPU as the limit. FS2020 only load one core hard and all others more or less sleeps.

I didnt mean to question that DCS was perfectly programmed but that we actually seeing a complete new release by one of the most powerfull companies in the bussiness. If anyone should have the power to make this about right they should. Its easy to understand the massive work and time needed to incorporate vulkan for ED, which I guess have quite small resources compared to microsoft...If it was a small and easy task to make FS2020 optimized we most definitive should have seen that on FS2020. I have accepted that DCS will be hard on hardware and I have invested to compansate for this earlier and also now, by ordering a Asus Strix 3090 OC to increase the performance.

I see tremendous difference in other games that has better coding. Still, with my hardware I am qiute happy how it works in DCS. I can achieve a descent picture quality and still have not stutter at all. As I wrote, I did order the 3090 to be able to increase the picture quality. As always, its a comprimize and with a better card I will be able to increase settings that earlier had to be tuned down to keep the game flowing without stutter(I dont like stutter at all). Also, getting the pimax 8KX and that will increase the load on the GPU so I think 3090 is a good choise for me. BTW, even if we think DCS is badly tuned from ED, Flighsimulator 2020 isnt that soft on hardware either and as it seems right now also most of the game engine running in one thread only loading a single core.
