Hey mate, if you're running a Reverb, there actually is no way to disable reprojection. The STEAMVR instructions that say you can turn it off don't apply to WMR HMDs, as they use a totally different API than Valve or Oculus headsets. We can adjust the type of reprojection, but it's impossible to run DCS without it.

Ha, interesting you should raise this point. I'm one of those people who HATE the rainbow effect, which is why my projectors have all been LCD models. I'm guessing those of us who grew up playing games and have done so for 20+ years have visual systems that are more sensitive to ghosting and rainbows.

Hey guys, Now that I've given up on VR, I can actually fly the Tomcat now rather than the menus. And hooo boy, how dang amazing is she! I'm seeing so many awesome details that I missed while flying in VR... and one of those is that the bloody pilot's name on my Cat's skin isn't mine! Those useless maintenance guys have obviously fogotten to update it ;) I'd love to get my name on an F-14 skin, and will happily donate a free module to anybody who can help. I'm playing the Cage the Bear campaign, so would love to get the skin used in this campaign with my name on it, as well as my mate's as my RIO and wingman (so one aircraft with me as pilot, him as RIO, and the opposite on the other Tomcat) My name: Bennett "GunSlingerAUS" Ring My mate's: Adam "Sentry" Phillips If you can chuck in skins for any other F-14 campaigns, as well as a few other popular Tomcat skins, even better. Heck, since I'm paying for your amazing work, if you could do the same for the F/A-18 (his favourite aircraft, childish Nintendo pilot), I'd be even more grateful. Please drop me a PM if you'd like to earn yourself that delicious new module you can't afford. Or I'd even take just one skin if it's a big chunk of work to do this - I have no idea if I'm being overly generous or a total Scrooge. Thanks artistically inclined pilots!

Thanks, but I've already tried DCS with the Vive and Cosmos, both of which had the exact same issue. And from what I've researched, Rift S users have this too - if you're running async warp/reprojection/smoothing/whatevernameused, ghosting and stuttering is an unfortunate by-product of the technique used to render fake frames. Some people just don't notice this, but I'm sure once they see a VR game without these issues, they'll never go back to it. Until they do though, they're having a ball with DCS! Lucky bastards ;)

Like I said in my OP, many users are quite happy flying with the current limitations of VR, and more power to them. I wish I could do the same, but I simply can't stand the glaring issues. I'm sure the problem doesn't lay with my hardware; in over two decades of testing hundreds of GPUs, CPUs, Displays, HMDs and more, I think I only screwed up benchmarks a couple of times. There is no margin for error when you have millions of eyeballs perusing your work, something I'm sure ED is more than familiar with ;)

I think the current hardware and software platform isn't too bad compared to Rift DK1 - you can be sure that the problem wasn't pebkac! If anything, I'd say a few people's Mark 1's were failing them :pilotfly:

My old buddy Toykilla ;) You've seen me say goodbye once before, during a fit of frustration, but this time I've actually unplugged my HMD and am enjoying DCS in stunning in 2D. It really is a beauty to behold. Alas, I don't think that Vulkan will solve all problems. For starters, it's an absolutely monumental task to port DCS over to a new API like Vulkan. I don't think ED will be able to do it without basically scrapping the existing engine. Secondly, just because it's using Vulkan doesn't mean the engine will utilise today's multi-cored CPUs. That also requires the software to be ported into a much more modular approach, which is very difficult when moving from a single-threaded approach. I really hope I'm wrong, but my experience suggests otherwise. Fingers crossed though, eh?

My first few hours flying DCS in VR with my HP Reverb and ninja PC (see specs below) were an utter revelation. Truly one of the most amazing gaming moments in my 35+ years of gaming. Sadly, this love affair proved to be a brief one. Despite my initial rapture, I soon realised that the VR experience simply wasn’t good enough in its present state. I could either live with extremely low resolution (well below the Reverb’s native resolution) and nearly all graphics details on low, or I could have relatively crisp visuals that chugged by with unsightly asynchronous projection artefacts including the entire terrain stuttering if I looked sideways, or close aircraft displaying a second ghost/shadow overlapping their fuselage. Add in a bunch of bugs such as flickering terrain shadows, night lighting going crazy, and more, and the experience is not ideal. I wouldn’t be expected to deal with these glaring issues in any other game, and I’m not one of the many who find the immersion of VR a bigger plus than these negatives. I wish I was! Heck, some people can't even notice the issues associated with asynchronous reprojection, lucky buggers! I’ve spent several months trying to get DCS to run well on the AU$1200 HMD I bought just for this purpose. Yes, several months. I’m very experienced in PC gaming hardware (I was extremely lucky enough to make a 20+ year career out of it), so please, save your tips and tweaks for somebody else – I’ve tried every possible solution you can think of. I’m sure many of you find your DCS running at 45fps with asynchronous reprojection to be fine, but I can't handle the artefacts that result. Until I have hardware fast enough to double the framerates I’m seeing in DCS (which will likely take at least four years), or ED really sinks their teeth into improving VR performance, I’m resting up my HMD, likely to sell it in the near future to try to recoup some of the purchase price. Given the huge portion of VR users in DCS (almost 2/3 of all people I polled in the Facebook DCS fan page, albeit only over the space of a day), I’m hopeful that ED will take a good look at the base game, and fix VR performance. Note that DCS isn’t the only simulation in having VR issues; of those I play, IL2 BoS also has some chugging framerates. In the meantime, I’m having an absolute blast flying DCS in 2D! I can see all the intricate details that make this such a stunning game, and it’s running beautifully. Sure, it’s not quite as immersive, but getting used to my TrackIR again took no time. I can once again appreciate what a wonderful piece of software DCS is. And I’m finally spending more time in the cockpit, rather than in the DCS and SteamVR options screens. To those who are currently enjoying the DCS VR experience, more props to you, and I hope I can join you soon.

Because two 2080 Ti cards are much more powerful than a single Titan, but only if SLI is working correctly.

Make that a +2. They're absolutely brilliant.

Hey mate, Toykilla is lucky enough to not perceive the ghosting or stutters that many, including you and I, see with reprojection turned on. But to drive 90fps in VR, even with all settings at low, you need an even better machine than mine. And that's even if you're flying a very basic machine over terrain with no buildings or trees. We can only hope ED works on VR performance.

Alas, dcs in VR has major issues, including bad and unstable performance.

YoYo, I had the exact same issue yesterday in IL2 - looked as if I had to focus way too close. Only fix for me was to run it at 90Hz with ASW on.

If DCS supported SLI in VR, I'd buy another 2080 Ti tomorrow. Heck, even if BF5 supported SLI I'd do the same.

Try just turning a light on, much quicker ;)

Can I ask if you're doing any kind of standardised testing each time? Your best approach is to do the exact same quick start mission each time you change something with VR. For example, I use the F14 quick start take off mission to see how changes affect performance. Take off with full burners, fly low over the town to the left, then head right over the trees, all with fps counter on. This demanding scenario quickly shows me whether I'm getting better or worse performance. In the absence of a dedicated benchmark mode, this is the best we can do. Having said that, VR in DCS leaves much to be desired, to the point that I'm now flying much more IL2 with its dependable and smooth performance. BTW, there's a lot of very weird advice on these forums, such as the 2080 Ti only working well when under extreme load, or changing your anisotropic filtering to improve performance, or that having a locked 45fps with ASW removes ghosting. As such I'd suggest going to a dedicated hardware forum for your given VR HMD instead of looking for advice here. You'll get more accurate information from specialised VR communities.

Get this all the time when I play at night and my room is dark - the Reverb is losing tracking. Turning my office light on then restarting WMR and it fixes it every time.

I've read that a recent Oculus update is the cause - I think it may have occurred in approximately the last week. Apparently the only fix is to use an older version of the Oculus suite of drivers and software, but it a pain to do this. I believe a patch is in the works as many people are reporting the exact same issue, but given the fact it's Xmas in a couple of days, I wouldn't expect this to arrive for at least a week. Good luck!

Please, please, PLEASE make it VR performance friendly! The existing carriers bring DCS to a shuddering halt due to their usual inclusion of so many performance-zapping aircraft on deck. Is there a clever way to populate the deck with "imitation" aircraft that make the deck look busy, without requiring the rendering of 10+ detailed Hornets or Cats up top?

Hmm, glitches as in incorrect models, polygons, etc? Or blur/fuzz due to resolution? Or perhaps some reprojection artefacts, which can look like shimmering, transparent squares on moving elements!?

Don't know version number off the top of my head, but I doa windows 10 update every few days. No problems like you describe.

Yep, 90fps is not possible for most missions at decent resolution. Personally, I find 60Hz/60FPS with no reprojection but high resolution much more tolerable than 90Hz/45FPS with higher detail, same resolution and motion projection enabed. I can't stand the awful stuttering and weird ghosting of reprojection. Even with reprojection set to the variable reprojection mode, flying the Tomcat in anything but the most basic mission over water is horrible, as it rarely, if ever, hits 90fps. This means reprojection is on most of the time. It may be fine for A2G MISSIONS provided you're always looking forward, not out the side or rear of your canopy, which may be why Toykilla isn't able to perceive the ghosting or stuttering that most can when reprojection is on. Unfortunately we have to make compromises until DCS is VR ready, and until then I'm sticking with a solid, smooth and crisp image at the lower refresh rate. Once you see the ghosting/stuttering after a few hours of flying, it's impossible to unsee.

Can I ask where you saw that you could change the motion projection type? Firstly, from everything I've read written by Valve on the matter, this setting has no effect on WMR, as the it only applies to Index and Vive. Also, the very nature of reprojection means that you absolutely must have the side effects I've written about; you don't appear to notice it, but it's definitely there.

Hey Oboe, that's really weird. Lowering the refresh rate shouldn't distort the image whatsoever. It simply lowers the times per second that the screen draws from 90 to 60.thr only visible effect of this is a slight flickering, which some people can tolerate, some can't. There's a good reason most HMDs now target a refresh rate of 85Hz or above. Unfortunately that is far too high to get a matching framerate in DCS unless you dramatically lower the resolution. And Toykilla, cool buddy. I'm pretty sure I learnt a thing or two about PCs during the 22 years I was a full time technology journalist, specialising in PC gaming hardware (real name Bennett Ring if you care to google me). I guess being the winner of best technology journalist in Australia means I should follow the advice of a novice? Perhaps I should get my old associate Palmer Luckey to vouch for me? Seriously though, apologies if we've let our clashing knowledge lead to anger. I would be happy to jump on Discord with you to explain how reprojection works, and what we mean when we refer to ghosting or stutters that results from this. You seem to be confusing the terminology and the technology itself. I'd rather spend ten minutes chatting about this than have more incorrect information lead new DCS VR users astray.

Double post due to my damn mobile phone!
