A new tweak for Reverb to keep it smooth


Recommended Posts

After months of trying to enjoy DCS in VR on my Reverb, I think I’ve found a good compromise that offers a smooth game, yet not sacrificing a crisp image.

 

The secret?

 

Lower your Reverb’s refresh rate to 60Hz. This means my 5GHz CPU and 2080 Ti actually has a chance of maintaining 60fps, and thus remove all async reprojection and its associated ghosts. While running at 60Hz was initially a little worse experience than running at 90Hz, my eyes soon adjusted to it, and the incredibly smooth effect of not having reprojection on is absolutely worth it. Until Dice fixes VR in DCS (it’s not just performance that is incredibly broken, the game has other issues like only rendering distant trees in one eye, rotating clouds, and many more) this is a fantastic solution for me to keep it running at 60fps while not having to drastically lower the resolution.

 

I think Reverb owners should give this a try. On my 5GHz i7/2080 Ti system I’ve had to lower many of the in-game graphics, but can keep textures high and shadows at medium (resulting in a nice, clear F-14 cockpit with realistic shadows). I run DCS at 2160 x 2119 via SteamVR with MSAA off, but VR PD at 1.2. While I do get jaggies on the ground, they’re hard to perceive in the air. Most other settings are set at low to medium – this drop is far less noticeable on the Reverb than on my 3440 x 1440 35” display.

 

If you want to try this, to lower your Reverb’s refresh rate to 60Hz, do the following.

Start WMR Portal

Click the three bars on the WMR portal’s side to open up the options

Then click “ … See more”, then settings, then Headset Display

Head to the section called “Experience Options” and hit “Change”

Select 60Hz, then close it all up, keeping WMR Portal open, then start SteamVR, and away you go!

 

Would love to hear your thoughts on this configuration – personally it’s changed my opinion on VR. I still can’t wait for ED to optimise the game for VR so that it runs as well as most other VR titles, when I’ll be able to crank up the resolution even more, but until then it’ll do me.

Interesting. Unlike you though, I can't stand reprojection; at close range it causes ghosting/double view of nearby aircraft, as well as huge stuttering of the ground. Instead I'm aiming to hit 60fps all the time so it doesn't kick in at all.

I have also been running my Reverb at 60Hz, it gives a much higher frame rate and smoother experience compared to 90Hz. I could not really see any perceptible drop in quality when moving down to 60Hz so have stuck with it.

I run Motionreprojection= Motionvector (@45FPS),PD@1.0 , SS-MS-AF off.

 

And 200% SS in the SteamVR Beta Setting.

 

In the NVIDIA Driver 3D Control Panel = low legacy Mode = Ultra.

 

Super Smooth, no ghosting at low level(even if you look sideways out of the Canopy), crisp and Sharp like Real.

Ah Toyboy, purveyor of absolute nonsense and misinformation. If you're runnijng at 45fps you do indeed have reprojection enabled. I'd love to have your mysterious optical system, as you apparently can't see the glaring flaws inherent with this technology. If you were running at 60 or 90 fps, it'd be a different story, but that is literally impossible with 200% SS.

Hmmm, .... it appears it is time to do a bit more testing. My #1 complaint with the Reverb and the whole WMP and SteamVR crap is the ghosting. Even on a 2080 Ti, I still see it all the time after trying numerous different settings.

One of the best ways to appreciate the beauty of the Multiverse is to learn the language in which it is written, ...... mathematics.

Without Motionreprojection, you have Ghosting everywhere... with PD 1.2 also...

I opened up Steam VR last night after it had updated and noticed my Reverb freq is now locked to 60Hz rather than 90Hz, has anyone else seen this?

I've realised that due to the resolution limitation, most graphics settings can be set to low. Crank up the SS to 120, medium shadows, water and draw distance, a Nd it purrs at 60fps. No reprojection artefacts, unless that God awful, performance devouring carrier comes into view. I can only imagine how terrible the new carrier will be.

Oh, and please ignore Toykilla, the guy has absolutely no idea about the reprojection ghosts/stutters that annoy the rest of us. His suggestions for settings are ludicrous.

What about your HP Refund for your Reverb and your lovely Monitor Gaming? What you wrote is absolutely bullshit . I think the only Problem is, that your Computer Dealer knows you in Person and sell you the Crappiest System he got...

 

Without Reprojection, DCS got Ghosting everywhere and dosen't run Smooth at all. A 60hz Display Refresh,is good for Smartphone VR,but nothing for PC Gaming.

 

BumSliderAss is not the person you can Trust at all

 

Don't waste your Time for his "solutions" .

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.

In our last conversation, we talk about Motionreprojection and the most Possible Smoothness for playing DCS in VR with the HP Reverb. From then to now, i fly Daily DCS with the Reverb, try almost all possible DCS Settings,Nvidia Control Panel Settings, SteamVR Settings and WMR Motionreprojection Settings.

 

If you say,you get Ghosting with Reprojection and can Solve the Problem with disabling MRP and reduce the Refresh Rate of your Display to 60Hz, something went wrong with your Setup. Forget what you read about MRP, it dosen't fits my Experience.

 

Try my Settings again with Motionreprojection @ Motionvector @ 45FPS Fixed on a 90Hz Display Refresh setting . This is the most perfect setting for me to Date,to geht a real experience in my Simulator. No Stuttering and no Ghosting @ all.

 

If you set SS,MS,AF or PD above 1.0 in DCS, the Problems with Ghosting and Stuttering begins, even on a High end System, because the high Display Resolution of the Reverb.

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.

No! It is not there and you are wrong. I test the last few Hours the new Patch again and fly Carrier Ops in the Normandy and a Mission over Nevada. Smooth as butter and no need for a Ghost Buster

 

You have to go to your Steam Apps Folder, Windows mixed Reality VrDriver/resources/Settings and put exactly this to your Default VRsettings File. On the picture you see the "Auto" Setting,because I was Racing before,where I'm Downloading the new Patch. It works great also,but you can put "Motionvector" in there to lock the frames to 45 Static.

 

After that, you can say goodbye to Ghosting and Stuttering. Use my Settings above. It works really well with the HP Reverb and it makes DCS to my favorite VR Application,because I'm a Simracer.b2b31a3485883b32aa63ed2c7f47ce7e.jpg

60 Hz and WMR is buggy still (Windows update from 1903). Nothing new with the last Steam VR beta 1.9.13., also, pity.

I could not imagine running 60 Hz in VR.

72 Hz in my Quest is about as low as I would want to go. Prefer the 80 Hz of my Rift S.

60 Hz = 60 FPS with motionreprojection on what is perfect for IL-2 or DCS but for WMR its a buggy still.

In an ideal World we would all be running 90hz. Using motionvector reprojection takes that 90 to 45 but adds some anomalies. These vr headsets weren't designed to use 60hz. I think that 60hz is there for the Windows Mixed Realty Portal not gaming.

 

I can run 90hz no reprojection 110 Steam SS and a PD of 1.1 for small engagements but deteriorates quickly if they grow. As Toy says, the best option for even the most powerful PC is still motionvector reprojection. Using the motionvector variable instead of the auto variable simply means you are forcing MVR always on versus it charging back and forth automatically while playing.

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.

Toykilla,

 

I saw your settings for the Reverb with Steam SS at 200 and Motionvector on, Nvidia Latency ultra low and I tried it. I liked what I saw very much! I did get stuttering very close to the ground looking out the side and I wondered if you have posted previously the rest of your DCS System Settings anywhere so I can try to match them. Looking for Textures, Terrain Textures MSAA SSAA Anistropic filter, shadows etc. Much appreciated!
