HP Reverb, Could do with some help

[crowdpleaser1989]

Hi All,

 

As a Rift CV1 user, I decided to upgrade to the HP Reverb a few days ago. In terms of resolution definitely an upgrade, so I'm very much impressed with this HMD. 

 

However I am getting some shady FPS drops which I just can't explain. First of all my rig:

 

Intel I8400 2.8-4Ghz 

RTX 2070 8GB

16GB ddr4 2666hz

SATA SSD installed windows+ IL2

HP Reverb

 

And some settings I use:

 

HP Reverb:

 

90Hz

SS180% (Will try to set this to 100% and see what happens)

 

Steam VR:

 

60HZ (I cant seem to adjust this anywhere, and googled unsuccessfully why this happened?)

SS180% (Will try to set this to 100% and see what happens)

 

IL2 Settings:

 

Monitor resolution 1024x786

Landscape normal

Shadows low

Mirrors Off

HRD Off

AA off

SSAO off

 

My normal FPS, in for example "Missions" Mig 3 scramble (airfield defence mission vs BF110's) I get 60 FPS no problem, sometimes dropping to 45 FPS.

 

I do however have issues on the Single player campaigns, for example Havoc over the Kuban with the A-20, but also with all other Single player campaigns.

 

Havoc over the Kuban  is one of the examples that I start on the strip with 30FPS, this is steady and doesn't ever go up until I am in air. The higher I fly the better the FPS goes, if I look up into the sky it goes up to 45FPS maximum. But when flying low on 30FPS it is simply unplayable. 

 

In order to try to fix this, I have tried the following: Set all options to the above described, without any noticeable difference, it is said turning some options off, grants 3-5 FPS per option, But im still stuck at that 30. Could it be something is forcing this FPS from the Reverb, or Steam VR? 

 

I'm confident that the more activity in the game, the lower the FPS gets. But reading a lot of your stories, I understand my findings do not overlap with yours. 

 

I have read that, IL2 is a very CPU intensive game, and that I can only use a single core? Is this still the case?

 

With that in mind, I decided to purchase a monitoring tool for FPS, CPU and GPU. I ran this in the Havoc over the Kuban single player campaign and observed the following:

 

FPS 30 average

CPU 33% in use (constant) 

CPU latency 15-20ms 

GPU 50% in use (constant)

GPU latency 15-18ms

RAM 9GB of 15 GB in use

 

The tools marks the CPU and GPU latency as orange, so this might be a bottleneck. However the usage of the CPU 33% (doesnt comply with 1 core, since I have a 6 core CPU) is not high, and the GPU (50%) is not high either. The same accounts for RAM, nothing special there.

 

I'm just wondering if I'm overlooking anything here, to be honest I'm kind off lost here.

 

Hopefully any of you can be of help with the experience you have.

 

Thanks in advance,

 

Alex

Open Windows Settings and click on Mixed Reality. Under Headset display select Visual quality to High and Resolution to Best Quality. There you can make IPD adjustments. Select the Experience options and choose 90Hz.

To get Steam fps target changed you need to go into Windows control panel and uninstall SteamVR for WMR. Restart your computer and reinstall SteamVR for WMR and it will pick up on your Reverb and set fps accordingly. https://store.steampowered.com/app/719950/Windows_Mixed_Reality_for_SteamVR/

Sorry I can't be more help at the moment. I'm heading out the door or would address your other questions/problems.

Hi Gordon,

 

Thanks, I'll reinstall SteamVR for WMR tonight!

180% on the Reverb sounds like a lot of pixels!

 

Basically to hit 90 FPS you need < 11ms for both CPU and GPU frame time. You're showing 15+ on both of those, which would mean you end up at 45 FPS interpolated. That might be fine (a lot of people are fine with 45 FPS interpolated). 30 FPS interpolated is going to be crap, but you look like you're doing better than that.

 

One IL2 setting you didn't mention is Low / Balanced / High / Ultra. This has a big effect especially on CPU. If I were you I would switch to Balanced and also reduce your SteamVR supersample, so you can get closer to 11ms.

 

Personally I really like Havoc over the Kuban campaign, but it has a lot of AI units which will burn a lot of CPU time. You might want to try some benchmarking in the "quick mission" instead, to rule out scripts and AI causing problems.

I am on the same boat:  CV1 -> HP Reverb since monday... ?

 

My sugestion, based on some research so far:

 

1) go to

//steamlibrary/steamapps/common/MixedRealityVRDriver/resources/settings     folder and edit the file named "default.vrsetting"  (better use Notepad++)

to "switch off" motion reprojection,  the line should look like this:

// "motionReprojectionMode" : "auto",

 

2) try to find nVidia & SteamVR & game setting combination  to achieve 60+ FPS most of Your playing time

 - regarding PD SteamVR and WMR for Steam recommned this pages:  https://vr4dcs.com/

- regarding the driver and game setting, I recommned  this forum

- do not push PD too much; 1.0 final ratio (i.e. reverb´s native resolution) is optimal here; more than ~1.3 causes ugly artifacts in reprojection (Microsoft says), so use antialiasing instead

 

3) go back to "default.vrsetting"  and  switch on the motion reprojection, i.e. line should look like this:

"motionReprojectionMode" : "auto",

or you can try

"motionReprojectionMode" : "motionvector",

but I prefer "auto"

Thanks for the effort guys,

 

Sadly I decided to return the Reverb, With a bit of a double feeling. I did some further troubleshooting with a friend of mine, whom is having the same issues with his Pimax. After some debate I decided to stick with a properly working CV1. I have left that in the box to ensure I don't feel the scare of the lesser quality screens in the CV1 coming from the Reverb.

...hmm, thats  strange ?, 

I have similar rig (CPU 4.7Ghz + GPU 1080Ti + 32GBRAM + SSDs) and I have own my CV1 fo 2+ years and have always prefered DCS to Box because my CV1 was significantly smoother in DCS; and can say, I really had put huge effort to tune the BOX up

Now, with reverb, I can say BOX is significantly smoother than was with CV1 and DCS is maybe the same, maybe little less smooth 

at the end -  it is your toy, your money and your decision   ?
