Vive pro2 settings advice please

[markturner1960]

Hi, can you Vive pro2 guys give me some advice on how best to set up SteamVr etc ? 

 

I have mine working now with what I guess are default settings as I have not changed anything in steamvr etc. Without FPSVR, it seems fine, clarity is great althought I do get some wierd artifacts, a little like a fresnel lense when panning my head sometimes. Overall, the clarity and resoltion is way better than my G2, but I do have a kind of stutter as scenery pans past, like it catches then releases every second or so, which is irritating. If I did not have FPSvr on, I would say it pretty damn good as a first try though. However on turning on FPSVR, its showing both my GPU and CPU frame times at 30 ms and my FPS at 30......so room for improvement there.

 

I dont have DCS in the apps drop down ( Remind me how to make it show there please? ) and the steam VR home settings are 90Hz, motion re projection not supported, render resolution auto, advanced supersample filtering is on and steam VR home custom resoltion multiplyer is 100% 3792 x 3792. However  FPSvr shows my steamVRresoltion at 150%, why is that? .

 

Can someone give me some pointers as to what to do to increase the performance and also, is there any kind of motion reprojection I can try? This gave me great result with the G2.

 

many thanks

I set my Vive Pro 2 in the Vive Console settings on Ultra I believe it is which is 90 Hz at native resolution. Do not use Auto It is 4896x2448 at 90 Hz.

Then in Steam VR, I leave the global resolution at default of 150% which is around 4kx4k per eye.

Then in DCS I set my Pixel Density to .7 which gives me around 2800 per eye.

I crank my DCS settings up pretty good and am able to maintain 45 fps. I do NOT use the Vive Motion Compensation, to me it looks way better without it long as I can maintain 45 fps.

 

Try the above and adjust your graphics settings in game and test. At my resolution I find I do not need any MSAA.

I can run it a little higher like .8 Pixel Density which is around 3200 per eye, but I get some fps drops down to 30 fps and a little stuttering.

This all can be very subjective.

 

For whatever reason I find trying to set resolution per a game profile in Steam VR does not work for me in DCS, it does not apply. Other sims and games it does, not sure why my DCS install seems to ignore the per game resolution setting in Steam VR.

 

Maybe this will help get you started in the right direction.

As he said, Don has some unusual situation going on in that he doesn't seem to be able to get the SteamVR SS settings to work in DCS. Because of this, he uses PD in DCS.  In general, it is better, and more common, to use only one process to determine SS, and that should be SteamVR SS.

In Don's case, he is using 150% in SteamVR and 0.7 PD in DCS.  That is equivalent to 74% (0.7*0.7*1.5) SteamVR for everyone else, i.e. 2736x2736 per eye.  I tend to use 90% (3030x3020) but really, you just want to experiment. Try 80% (with PD 1.0) as a good starting point.

I agree with Don when he recommends not using Motion Compensation.  The current implementation is very poor, with horrible graphical glitches and artefacts all over the place. We can only assume that his will improve over time.

I also agree that Ultra Setting (in Vive Console) is best, giving native res at 90Hz.

Thanks, I had a chance to try this advice earlier today and have come away confused.....Using the settings recommended by Imacken, clarity and visual quality were not great - and I was still in the mid 20's with frame times. It was really horribly shimmery without the MSAA x2, so I turned that back on. Buildings and tres etc looked less sharp. ( Of course, I guess they would as my previous settings were higher). To be honest, It was almost worse than my G2.

 

Just to see, I set the settings back to what I guess were the default from the installation as mentioned above. performance seemed better visually and in frame times than before, mid 20's. I left the display settings in vive console at auto, instead of high or ultra and went back to 150% in steam vr. It looked way better and to be honest, if I did not have FPSVR giving me the readouts, I would have been unable to tell the difference in performance. All of this with PD in DCS at 1.

 

Motion compensation is another one, my vive console says its not available as my graphics card does not support it?

 

So I am wondering why settings that should have given me frame times in the teens, did not, I was getting mid teens frame times using my G2 on my old PC with a 2080ti, with the same settings ( see my sig) 

 

I am also getting lots of problems with the lenses steamimg up.....

 

I remember spending an very frustrating week getting my G2 working correctly, looks like this is going the same way....

[imacken]

I would not recommend using auto as you have no idea what it is going to set your resolution to. 
Set it to ultra and vary the SteamVR SS values. 
150% is way too high, IMO. I’m not surprised you’re  getting FPS in the 20s. 

[markturner1960]

Yeah, but using the settings you posted, it was the same, which is why I am scratching my head, you would have expected with dropping the rsolution, that the performance would increase, but it appeared not to - well, it improved, but nowhere near what I was expecting.....( By the way, I am absolutely not naysaying your advice, which has always been spot on, I just think there is something else going on as well, or why would we not see the reduced frame times expected? Those settings give me mid teens with 2080ti.....) 

 

I will have another tinker today and report back. Thanks for the help ! 

[imacken]

Yep, must be something else going on. But, I would still highly recommend NOT using Auto res.

 

At 90% (~3000x3000), I'm getting a solid good looking 45 fps.  In fact, I might change my view on recommending Ultra, as yesterday, I went back to using Extreme - native at 120Hz - setting in Vive Console, and to my surprise I am getting a pretty rock solid 60 fps.

 

Another thing worth mentioning, is HAGS.  That affects performance a lot, and also changes the pixel count at the same SS %age.  What do you have that set to?  I would recommend it be switched off.

[markturner1960]

I checked, HAGS is off. You know, its strange - when running lower settings, I get a noticeable stutter when looking out the side of the jet, really disconcerting. Cockpit is generally pretty sharp, but there is a general blurriness to everything else outside, which is unexpected.

 

By the way, in FPSvr, which FPS readout do you use? The one in left pane, or the one in the right ( which is average FPS I believe?) Whilst testing I noticed a strange thing, the left readout of FPS was fluctuating around 40 -50, yet my average FPS reading was around 90 or 100 .....? 

 

I am currently running at extreme, and have tried various settings of SS in steam VR.....at 90% I am getting more juddering out the side view and around 16 ms GPU frame time. At SS 150%, its way smoother, juddering almost gone, but frame time at around 22 - 25. In all scenarios, my CPU frame time is running high twenties and no noticeable difference in external clarity. 

 

I am inclined to stick at the higher setting as its much nicer to use and smoother. Any ideas on the general blurriness outside? I dont remember it being so bad with my G2, on the old system. It should be way better on the Pro 2 at extreme setting and 150% should it not? The steam SS setting does not appear to vary the clarity much, but rather seems to affect the smoothness, so lord knows whats going on. But its working OK and I am reasonably happy.

 

One thing, its tricky to get the headset in the optimum position and cant say I notice the FOV difference from the G2 at all.....But way less cranky getting it all to work, just turn it on and go, so much better than all that malarky with WMR

Is there an easy way to record what I see, so I can post it up for comment? 

[imacken]

I'm afraid I'm not seeing the behaviour you describe at all.

At 90%, i don't see any stuttering to talk about at the side view, and at 150%, I'm seeing horrible frame times of 20ms+, but no stuttering outside either.

What does SteamVR say for number of pixels at 150%?

I'm also mystified by the FOV comparison.  Obviously, it depends on where you have positioned the lenses with the adjustment knob, but it is easy to see the difference in the SteamVR home 'moonscape' scene where the 45 degree radial lines are drawn from your position.  With the VP2 I see much wider than the 2 45 degree lines , whereas with the G2, I was just seeing the lines at the periphery.

[markturner1960]

Yes, it is wierd - but I can only describe what I see! There is so much mucking around required to get DCS running VR correctly, its frustrating. Out of interest what are your CPU frame times like? Mine are higher generally than the GPU times. 

 

I have the lenses almost as near to my eyes as possible, it seems better like that. My comment was subjective and not based on measurements, I just meant that its touted as a big deal, but I did not really notice it. I think will do some side by side comparisons with both machines. 

 

Back at the sim PC's Thursday evening so it will be the weekend before I can do some furtehr testing and tweaking etc. 

 

Thanks! 

[imacken]

My CPU times are (more or less) always way less than the GPU ones. I don’t know anything about AMD CPUs, but could that be part of the problem, do you think?

What res (pixels) is SteamVR reporting for your at 150%?

Hi,

 

 I have been testing my new VP2, and trying the settings shown in this thread. Disabling motion smoothing (which is horrible) I get stable performance (45 FPS) at 100% and even 120%, where the picture is quite clear using MSAA x2. But when I flight low and look to my side, the building, trees and vehicles suffer from stuttering, which is a bit annoying.  Otherwise, everything seems very nice.

 

BTW, my rig is based on a 10900K@5.1 and 3090.
