Help with Reverb G2 RTX 3090 settings

[Mukai92]

Hello all, been a looooong time since I last booted up DCS. Havn't flown since 2020 (rough year and had to go into a smaller house) so I'm very rusty on the whole VR side of things.

Bounced back and I've a Reverb G2 and an RTX 3090 with a ryzen 5800x. I had my 2020 settings still set up for my oculus CV1 but when playing with these settings i'm getting awful performance.

I see loads of talk of mods for FSR and shaders and all that but I'm like a dear in the headlights. Could someone give me a good base line settings and what mods to install? I'd be forever grateful! I'm really itching to get back to the battlefield :)

Hello, ther is lots of guides over there, first you must see that in DCS the PD in the vr tab is in 1.0

then play with wmr settings and steam setting.

For me , works fine steam at 100% resolution and in video mode for dcs 100% resolution and in retroprojection always on. this forces the fps to 45 but you will not see lag or blurriness

In WMR, the video tab in retropojection use "steam settings"

In game try terrain shadows off,

shadows :i have them on medium ,

msaa off and ssaa x2 (msaa is a great frameseater, but with a 3090 you must try the opposite : msaa :x2 and ssaa :0)

Water medium 

and with this I have 45 solid FPS with no blurr in almost all the terrains except marianas

factor trees I have them on 50% and visibility  to medium or far.

I am using only  the VRPERFKIT and all goes fine.

Hope this help you

Cheers man!! Really appreciate this. I did have a look at some of the guides but some of the more specific ones (related to reverb) just went completely over my head and confused me. Cheers again!!

If you need more help (screenshots or something else) ask for them.

Reverb G2, WMR and DCS are hard to config for a smooth use....most is try and retry....

As I said, this works for me with a reverb G2, I9-10850k, 32gb ram stored in a SSD and with a rtx 3080ti

Kind of hard to go wrong with a 3090...

Start tuning using free flight over caucasus, that allows you to focus on GPU performance without worrying about CPU bottlenecks

If you have any old AMD drivers on your system, get rid of them completely using DDU

Make sure your motherboard bios is up to date

Plug G2 into a USB port directly wired to the motherboard (usually best to pick one on the back, you might have to try a couple to find one that works best).  That big ole cable is very finicky. You want the latest version of that cable (how old is your headset?) and it needs a USB port it likes, and that USB port needs the latest drivers.  

Clean out your shaders caches and let's get on with it.  

Settings:

1. In DCS, why don't you just start with the VR presets.  Set pixel density to 1.0.  NOTE:  turn MSAA off. 

2. In Steam VR, set global resolution to 100%.  There are two places to set this (General and Video) and they do the same thing.  Just focus on the "Video" tab. Note, "100%" is a bit more than your native resolution, it should be about 3100x3100.  Trust me, just roll with it. 

3. Start DCS, then go back into Steam VR settings.  You can either hit the menu button on your right controller (the one with three lines) or else take off your headset and pull up the settings menu from the destop app (the little teeny SteamVR app). Under "Video," click "per-app" settings, and set THAT resolution to 100% also.

Take her for a spin.  You should be nailing 90fps up in the air, looking up at the sky.

From there, I'd work on my DCS graphics settings next, add as much eyecandy as you must without making it puke.  EXCEPT for MSAA.  Hold off on that for now.  You should be able to set vis range to high, at least.  AF to max, trees to max.  Water to medium at least.  Should be able to run some shadows but you may not be able to max that out; medium cockpit shadows and flat terrain shadows is probably a good bet (if you must).  Clouds is a whole nuther thing, maybe best to leave that on low till you get a chance to read up on it.  Just mess around with it, but don't mess with MSAA just yet.

Now.  Once you find a formula that works for you, you can finally start work on your antialiasing. Two ways of doing that. 

The easy way is to increase SteamVR resolution.  Just don't get yourself all twisted up. You have three knobs to work with (Steam General, Steam Per App, and DCS Pixel Density).  Don't try to adjust multiple variables, they all do the same thing. Pick one.  (I usually adjust Steam Global because it's not buried under so many submenus, and it takes effect on the fly.  You can pick whichever one you want.  ONE.)

The harder way is to try to use some MSAA. Harder because it crushes performance.

I would only change one at a time. So for example compare this:

-- Steam Global 100, Steam Per App 100, PD 1.0, MSAAx2

to

-- Steam Global 130, Steam Per App 100, PD 1.0, MSAA off

Which one do you like best? 

Good news is, VR optimization has come a long way, you'll be pleasantly surprised at what you can do with eyecandy.  Bad news: even with a 3090, trying to supersample AND use MSAA at the same time may make your system puke.  Strike that: it will make your system puke.  The old days of running PD 1.4 and MSAAx4 to prevent yourself from going blind with your Rift CV1 are over, my brother.  You have WAY too many pixels to drive now, and your new headset is not a pig, and it does not require that kind of lipstick.  (The other bad news is, MFD readability still sucks donkey balls.  We can discuss solutions at a later date; don't sweat it for now.)

You don't have to use an upscaler like VR Perf Toolkit or FSR for VR with a 3090.  We can discuss why you might want to but first get it running, then we can talk about that stuff.  Also don't worry about your WMR settings just yet, set all that stuff to auto for now and don't worry about motion reprojection.   You'll eventually need "motion vector" to smooth out some of the judder when you're flying down low,  but even without it, flying around at 15 or 20,000 feet everything should be smooth as butter.   

Many of us are using fpsVR to monitor the effect of these settings; it's an inexpensive utility you can find in the Steam store.  It isn't perfect -- you'll run more smoothly without it -- but it's accurate and highly useful for tracking your GPU times.   Some of your graphics settings will have a subtle effect on FPS but a measurable and reproducible effect on GPU time.  You're flying blind without it, so just shell out the four bucks and get it.  

Don't get yourself all twisted up in knots.  Just get the thing running.  Native resolution (100/100/1.0) without MSAA.  From there, baby steps.

I know I'm seeing this thread a week late, but I just wanted to say to all three of you: THANK YOU!  Mukai92, I was about to make a post just like yours as I'm basically in the exact same boat (well, with a 3080, but still...).

Firefox and Delta Mike, thanks for taking the time to spell it out so clearly. I had pages of notes gleaned from various threads here (some with years-old info that is now largely defunct), as well as various other sources, and it was such a rat's nest of inter-tangled ideas that it's been keeping me away from trying VR in DCS for a very long time. 

This hobby of ours can be intensely frustrating, just getting things working right. Sometimes I think what DCS simulates best is a combat aircraft's 20:1 ratio of maintenance man hours to actual flight hours. Anyway, this community makes it all worth it. Thanks again.

Yeah I was watching my son-in-law in action the other night.  Tuning in flat screen mode, I take it, consists of putting every slider all the way to the right,  and then (if you can)  brag about what FPS you're getting.  "What does that do?"  "I dunno, I don't care, I'm putting it at eleven!"   Tuning in VR is totally different; it's all about making the game playable:

•  It doesn’t make you puke.
• Motion is reasonably smooth. 
• You can see well enough to play.  You can read your MFD’s, for example; and can spot your targets.

The 3090 can accomplish those things with one hand tied behind its back, all you gotta do is run your G2 at native resolution (100/100/1.0) and you're done, basically.    Everything else is peripheral.  Believe me, when you're trying to put ordinance on a target, or trying to catch that 3-wire, the last thing going through your mind is, "Darn ED!  When are they gonna give us some decent tree detail factors!"  Trying to pick up a chopper right on the deck, flying in straight out of the sun... Strike yelling in one ear, Bitchin Betty in the other... "If only the clouds were prettier, I'd wear that little bastard out"

Hey all! Was away for a bit but got a chance to follow some of your advice. It's greatly appreciated!! 

Was able to get 45fps with 2x msaa. (30fps on supercarrier) I enabled motion reprojection and that made a big difference in exchange for some ghosting. 

I'm getting some frame drops that is a bit annoying but I need to iron it out, I'm just missing something I think

 

Again thanks a million guys!!

Yeah you still have a leak somewhere. Post up a screen shot of your DCS settings and get some data from fpsVR.  Also hit up Speed-of-Heat, he wrote the book on tuning the 3090
