eyh ! thanks for the insight. that's great to have those feedback. if you want to save time, i did an article on reddit about how memory affect performances in DCS VR, check it out also, could you please share Vram usage of the two card please ? On SteamVR i think we will see 3080's vram almost capping its 10gb but i wonder how the 16 gb of the 6800xt are filled. but i trully dont know the Pixmax so maybe its vram usage will be different from a regular htc Vive. benchmark usually put the slightly 3080 in front of the 6800xt in 80% of games but since DCS have nothing to compare to anything... =D

a 5950x will indeed make quite a difference =D even in DCS ! that said, you'll still struggle to get 45 fps in heavily loaded MP servers. Playing in not that crowded MP servers will should be fine though !

yeah someone pointed this resolution maths to me, appearently i didn't understood well how PD and SteamVR SS% works. but i'm too lazy to check =D and the overall result would be not that relevant anyway since maybe Valve Index doesn't need that much (or more?) oversampling to be readable because of its native increased resolution. No i didn't tried to overclock the i5 because that's not my computer and i dont want to breaks it =D that said, performances scale well with frequency. I5 9600k have a turbo mode that allow it to go to run at 4.6ghz (and i believe it does in DCS since its monocore and shouldn't trigger thermal throttling. it has a corsair H80 on it. But i didn't checked). going up to 5ghz would result in an increase of performances of about 8%.

Hello guys, i wrote on reddit a post about tests i made during the past 3 days about DCS VR and how it rely on Hardware. Especially CPU and Ram which are often neglected for GPUs and are, in often, the actual problem. If you guys have any questions please ask them on reddit as i might forgot to come back here to check if there are comments and answer them. Hope it might help. Moderators, Feel free to move this post to any section of the forum it i'm in the wrong one ! the post: https://www.reddit.com/r/hoggit/comm...re_and_dcs_vr/ the content Hi Everyone, I noticed a reccurent problem into the hoggit's community. Either people dont know shit about computers and just go for most expensive parts, (which kinda works...) Either peoples dont know shit about computers and dont buy PC parts. Because they're broke. Or have better things to do than putting 1600$ for a GPU and 1000$ for a CPU that aren't even available anyway. =D So i decided to take a bit of my precious time (few fucking days, actually) to demistify things for you. Important notions to keep in mind concerning DCS's behavior with hardware. And if you dont agree with that you should really have VERY SOLID arguments AND proof. GPU just need to keep up with CPU The goal is 45 fps in Asynchronous reprojection. (we're poor, remember ? also realistics.) DCS's core engine is cursed. HARDWARE now the setup for you to have an idea of what to expect. Its the "cheapest" setup i could do with amd's lastest release. (i like small motherboards and got a very good deal on this one. i've nothing to compensate ok? same for the ssd =D) Gigabyte B550i Aorus Pro AX AMD 5600x 2*16Gb 3733C16 Dual Rank Micron E-Die Sabrent 500gb PCIe gen 4 SSD GTX 2070 super 8Gb what you must remember from that : any b550 motherboard will do. X570's features are irrelevant. this is the cheapest new Zen 3 processor This is actually a 3000c15 kit running at 3733c16. we will discuss that later any SSD will do, just avoid HDD the GPU is what it is. it's borrowed (i own a gtx1080) and i dont have any better so... I also borrowed and tested the whole computer coming with the 2070s which is Asus TUF z390-Pro Gaming I5 9600k 4*8Gb 3433c16 Single Rank Samsung B-die Samsung 970 Evo Plus 500gb (Pcie gen 3 SSD) same GTX 2070 super note : even if i didnt cover overclocking, on Intel's plateform is not doable without a Z390-490 chipset and a K cpu. BENCHMARK I setuped a F18 scene around Kutaisi. a pass at low altitude without TGP, a loop looking in the sky then the ground without TGP and a pass at low with TGP. Those 3 scenario cover things good enough for the purpose of the demonstration. you can have a look at the scene in the link below. Does i benchmarked Multiplayer ? Well, yes but not much. the reason is that Kegetys's Shader doesn't IC Pass so most servers are inaccessible. i disabled it and did few tests on the Grownling Sidewinder server though but since my GPU couldn't keep up it was not very relevant. Informations are given to you in Millisecond from FPS VR. That's quite inacurate but the best i can find and good enough since we wont notice a difference below 1ms (or even more than that.) Settings will be detailed in a picture. I'm running last OB patch with Shader VR Mode from Kegetys (man if you're reading this, big shootout to you \o/) DCS's oversampling is set at 1.3 and SteamVR's at 1.5 for a total of 1.95. why ? because that's my sweet spot for readability, and GPU's performance. The marging of error is quite big and nothing belows 1ms of Delta will really matter INTERPRETING THE NUMBERS (edit)I might have skipt this entire section... sorry for that =D. I know those numbers are not the FPS we're used to. Long story short : The Lower The Better. Those numbers are the time needed for either the CPU or the GPU to render a frame. To allow a certain amount of FPS you need those number to be below the time that sit between two frames. For example at 90 fps you need to render a frame each 1000/90 = 11.1ms. which give the following table for the 2 commons refresh rate found on HMD's 90 fps for HTC Vive/Oculus Rift kind of HMD's 11.1ms for 90fps 22.2ms for 45fps with asynchronous reprojection at 100% 120 fps for Valve Index and such (which support 80 and 90 fps by the way) 8.3ms for 120fps 16.67ms for 60 fps with asynchronous reprojection at 100% To have a rough idea where performances would sit with any HMD on the market you can extrapolate HMD's resolution x Oversampling. As stated, i'm using here 150% on Steam VR and 1.3 on DCS's Pixel density. So 1.5x1.3=1.95. I'm using a HTC Vive which use a 2160x1200 panel so i need to push at least 4212x2340 pixels every 22.2 milliseconds into the HMD in order to achieve those 45fps with 100% reprojection. to keep the Valve Index for example you should achieve similar result running Steam VR at ~112% and DCS's Pixel Density at 1.3 Chapter One : The CPU First question : Does the CPU Clock matter : MEH 5600x runing at 4.65ghz max 12/10/12ms 5600x running at 4.85ghz max 12/10/12ms Of course CPU clock matter but that's not relevant for a ~5% increase and i didn't worked on CPU clock yet. Tools aren't available (yet ?) to figure what core can go how high and i wansn't willing to do that search by hand. Second question : Does the CPU Matter at all ? Well... MP 5600x stock (4.65ghz) : 25.6/18/21 MP 9600k stock (4.2ghz) : 27/18/21 SP 5600x stock (4.65ghz) : 12/10/12 SP 9600k stock (4.2ghz) : 14/11.4/15 At this point i have to clarify something. AMD Zen 3 cpus are known for having the best single core performances on the market currently. Cinebench R20 Single core performance of the 5600x is 604 while 9600k's is 481. that's ~20% More raw performances. While it translate rather well in SP, in MP it doesn't. I suspect the GPU bottlenecking the CPU here since GPUs stats are as follow MP 5600x GPU : 22/22/22 MP 9600k GPU : 22/22/22 SP 5600x GPU : 15/15/15 SP 9600k GPU : 15/15/15 Also for the rest of the tests, Globaly GPU always sit between 13 and 17 as long as the CPU can keeps up. Does DCS care about SMT ? (AMD's equivalent of hyperthreading). NO MP SMT Off : CPU:20-25ms, GPU 20-25ms MP SMT On : CPU:20-25ms, GPU 20-25ms yeah, i know those numbers are probably GPU limited but in fact, almost all my tests are done SMT off since i forgot to turn it back on And its another variable i dont have to worry about anymore... its a win win ! Chapter 2 : the Ram ! Here is what i spent days doing. fine tunning those fuckers just to discover that Zen 3's bios are fucked right now and cant go beyond 1900 of Fclck. Mine actually is stuck at 1866.) all thoses tests were made in SP with Shader mod On except those where i explicitly tell that they are Multiplayer. First : Does the speed of the ram have an impact ? YES. well, a bit 2133C16 UnCoupled : 20/13/20 3200C16 UnCoupled : 14/12/15 3733C16 Uncoupled : 13/12/15 as long as you go past 3000 or 3200 you should be fine though Do i need to run ram in Coupled mode (fclock = ram speed/2) or not : YES, BY A LOT 3733C16 UnCoupled : 13/12/15 3733C16 Coupled : 11.5/10/13.5 Does DCS Care about Ram's timing and subtimings. running at 3733 Coupled ? No. C16-20-16-16-38 : 11.5/10/13.5 C16-20-20-20-40 : 11/10/14 C18-20-20-20-40 : 11/10/14 C20-20-20-20-40 : 12/10/15 Well, ok. yeah it does a liiiiittle bit. but if you're running your ram at C20 you are doing it wrong. Wanna go further ? Lets go further ! Does DCS Care about running very high frequency of ram ? No. 2*8gb at 4400c18-20-18-18-38 : 11/10/14 had to use the samsung B-die kit for that. the ram was unstable but i managed to get results anyway. Can DCS run on 8gb of Ram in Single Player? eeeehhhh... 1*8gb 12.5/12/15. Ram usage : 7.3gb 2*8gb 11/10/14. Ram usage : 10.9gb Can DCS run on 16gb of ram in Multi Player ? eeeeehhhh...² 2*8gb CPU 20-25ms, GPU 19-20ms, Ram usage 14.8gb 2*16gb CPU 18-23ms, GPU 19-20ms, Ram usage 18gb that's why you often hear to get 32gb of ram at least. Choosing a Kit of ram is trully a whole different topic and i wont go into that. You can go for Crucial Ballistix 3000-3200 2*16gb kit (that's all the same), they're perfect for the job and rather cheap. Also keep in mind that my windows is fresh and running only DCS, monitoring tools and OBS for recording. Conclusions Thanks for reading all that. Long Story short, This new generation of processor wont revolutionize DCS's performances in VR but it is now trully doable without an expensive intel plateform. Especially with mid range GPU coming along (~3060 ~6600-6700xt), i believe we will be able to run DCS VR in Okay condition within the next year. I didn't do all those bench with my GTX 1080 but, even if slighly slower than a 2070s, it runs the game totally fine with the same settings. i hope anyway it helps people like me, that doesn't want to spend thousand in hardware but still want to get decent performances and readability in VR. I trully cant play on flat screen anymore and even if it's not perfect in all case scenario, i'm now able to play my favorite game in VR. Coming from a 3770k, it's an overall big leap in performances for me anyway ! If you have further question, please ask, i'll do my best to answer ! just doesn't ask me to tweak graphics settings to be able to play well in MP, i'm already at the bare minimum, every aspects wise =D To ED : if you read this guys, thank's for all the work you've done on optimisation. Its trully something we need and we'll always be thanksful to you to do this ungrateful work ! I know you know about Kegetys's work on Shader VR Mod and i hope one day you could impletement something like that or create an exception rule to IC pass for servers to allow that kind of mod and reduce the GPU's load. Thanks guys and fly safe.

and what about JHMCS target designation ? isn't the FA18's pilot capable of designating ground target with the JHMCS ? i believe there would be some kind of symbology to see where the JHMCS/tgp is pointing at?

+1 for absolute axis. being able to bind it to button for relative axis makes sense but on an axis, that feel odd

Cool, thanks !

i got problem with cold start / empty loadout too. cold start in SP, empty load AGM62 on station 2 and 8 + pod on ventral take off then warm the 62 got image from 62 (WE squared) + image from DL pod (DL13 squared) set a waypoint as target, uncage the 62, get to the launch zone. Loose weapon when in range. I do have video feed from the DL just before launch but when the bomb drop the DL feed become some kind of white static noise and dont provide any feedback from the 62. both channel tested. is that the same bug or is that a new one ? thanks !

bru-41a with mk82a used to work correctly until a certain patch broke it. i addressed the bug for the training variant and it was fixed but unfortunatly that didn't fixe the mk82 variant. (which it make me wonder how poorly bugs are patched...) after repporting the bug on the MK82's it was moved into "wish list" by a moderator

yeah i know. that's why i put it in the wish list. i believe it might be possible to create a mod for this but i have no clue on how to do this.

up I dont mind breaking the IC. I'm sorry nthere i dont speak your language

It is on AI's F16 blk 52, the model is here, warhead is here, the flight model is here, the CSID is here. We only miss Stores pages informations for it to be launched from our beloved F18 =D While you're at it, would you do a bru55 dual version of it too, please ? =D Thanks a lot :)

I'm glad this thread move up some passion because i'm also Fun > hardcore realism. I'm totally fine with DCS being a hardcore simulatiok and that's even why i'm still playing it. Complexity is a beautiful thing. But that's still a game and people should have fun with games. Carrying 6 mk 82 on a pylon is cool and the f18 is capable of that. That's not like if we wanted to put a B52's 12 mk82 bomb dispenser tho... (I tried on a A10, the game just crashed xD) Still. Something worked, dont work anymore and letting it unpatched while being aware of it is... Arguable from professionnals. I know you all are busy but still... I'm glad it moved to wish list though ! Its a wish indeed :)
