VR Discussions, Questions & Feedback

Just to "chip" in on performance fluctuations. I 've had none.

I used to have an oculus rift CV and a 2070 super card. Then I moved to a Reverb G2 headset. Recently I upgraded my GFX card to a 6900XT. I also upgraded from a 2700x to 5800x CPU.

In all of my configurations performance has always been super predictable since AMS2 came out. The only thing that sets up performance is rain / night racing and mostly because of car headlights.

To get the performance I want I go to the track which gives me poorest performance, which used to be SPA (not anymore after recent update with optimizations). I then set the settings so that my gpu is never exceeding 90% usage in daylight. This guarantees flawless 90fps performance on all tracks with all AI cars consistently no dips ever.

The only issue I had when going to G2 is that motion smoothing was not working well with AMS2. It would many times brake for no apparent reason (fps goes up motion smoothing stops). which is annoying because I prefer to put it on automatic so it automatically activates when cars are putting on their headlights. Yesterday however I found out that to rely on auto motion smoothing I have to set force directx 11 mode on in the WMR settings within steamvr. Then it works significantly better for my setup. Yesterday I had awesome nighracing with only very minimal stuttering because motion smoothing was slightly misbehaving every now and then.

 

Have the mirrors changed? My view in them barely moves with head movement now, I'm sure it used to follow my head 1:1.

 

What settings do you have in tray tool?

 

Ok, more info for @Chip and gang from yet another night of testing (sorry for long post).... but progress! (I think).... I delved deep into the rabbit hole of WMR/G2/SteamVR and DCS/Elite forums to get other folks' experiences with fluctuating framerates and low GPU/CPU, especially in reprojection..... here's where I got to tonight which is the best performance from all testing yet.

Remember, 5950x/3090/G2/32GB - so I'm sure a lot of this will be WMR/G2/Nvidia Driver and even AMD dependant.... so your mileage may vary!

IMPORTANT - I learnt this tonight...in order to have wildly different experiences between gaming sessions whilst previously trying to tune them in. ...

1. When loading the game, do it in this order. Fire up WMR, then Steam, then SteamVR, then AMS2.
2. When changing settings (Nvidia, Steam, or other)..., exit game, CLOSE and then restart steamVR before then restarting AMS2.

This gave be much more predictable results, and the previous WTF, I didn't change anything and it's gone to sh!t stopped happening.... GREAT, a baseline to test from.

I'm also driving a baseline to try and benchmark against with a goal of a solid 45fps/repro. Here, it's Donny in the Cat Superlights - 13/10/2020 at 4pm (real-weather... raining!) in a race with a full grid. As I got this close to perfection, I tried Suzuka at 7pm (same date) and night still KILLS things... but it's easier to see the impact on settings at Suzuka due to it starting off at 25fps. I'm running Steam at 100% SS and force-on in SteamVR app settings (I've left the WMR setting to Steam-app setting, not motion reprojection).

- HAGS ON. This definitely improved things
- WMR Setting (in VR overlay) - Force DX11 Mode (edit: faster, but does reduce graphics lighting quality… have reverted this)
- Nvidia Control Panel
- Threaded optimisation: OFF (definite impact)
- Power Management: Prefer max perf.
- Low Latency: ULTRA (definite impact)
- Triple Buffering: ON (who knows...)
- VSync: ON (who knows....)

The other thing I did as an AMD user was disable all PBO and OC in the bios - this DEFINITELY helped with frame stability too.

With this I can see it's the GPU running out of steam before frame drops as it's regularly in high 80's or early 90's before this happens.

Hope this helps.... I'll keep testing.... one day we'll get there!

 

These are what I'm using at the moment.

 

Thanks man much appreciated

Great info! I will try to test tonight. Are you still using Lasso program as well?

Other things I've done
virtual monitor pre-allocation:

1. Launch Registry Editor
2. Navigate to “HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Holographic”
3. If the “PreallocateVirtualMonitors” REG_DWORD is not present, create it by selecting Edit > New > DWORD (32-bit) Value and entering PreallocateVirtualMonitors as the name
4. If the “PreallocateVirtualMonitors” REG_DWORD is present (or you just created it), double-click the entry and change “Value data” to 0
   Then reboot your system

 

My nvidia control panel isn’t the same as what’s in your pictures??? Looks similar but I have some different options.

 

Welcome back Steve, we’ve been eagerly waiting for you! Thanks for this, will start tinkering.

just to be clear, you’re getting 90fps at ultra in all conditions at 350% SS on G2/3090 combo? With a bit of help from OpenVR FSR? Just wondering what I’m shooting at. To be fair I’ll be over the moon at 100%SS and true 90fps on the G2

Which Nvidia driver version please? Game ready or other? OpenVRFSR settings?

any other SteamVR/WMR stuff we need to know? Are you AMD CPU too?

thanks

 

350 was a bit much, I usually go for about 250-275
OpenVR FSR
renderScale": 0.69
tune sharpness to about .73
Nvidia Driver is the latest 471.96 using NVCleanstall_1.10.0 just checking these options

 

Here are my system specs:
Z390 AORUS ULTRA, i9-9900K CPU @3.60GHz, O/C to 5.1GHz , 1TB PCIe SSD, 16GB Ram, Nvidia GEForce RTX3090, AccuForce Pro V2 Steering System, Fanatec ClubSport Pedals V3, SHH Shifter, HP Reverb G2

 

Thanks - out of interest, why not 100% without OpenVR FRS?

I'm also slightly different on the Nvidia driver options.... but just waiting for the indexing disablement to finish and then I'll be giving it a blast!

 

no overall difference for me.

 

Wow, that is shocking! after all those changes I saw double performance. Don't know what else to help with. 100 % steam vr is what I'm using.. Only 200 - 250% SS on per application for ASM2. Just looks clearer. Don't know about AMD vs Intel?

 

Right regarding nvidia control panel I have set all settings now as yours but on antialiasing transparency setting I have no option?? It says OFF with no drop down facility to set it to anything else and I notice you have a setting of 8x super sampling…..how did you get that?

Thanks in advance
Baz

 

Hi guys, i cant start the AMS2 on VR, other sims works and start fine but AMS2 is start only single screen, can anyone help me please?

 

Go in your documents folder and delete graphicsconfigdx11 and graphicsconfigopenvrdx11
It should boot into VR then. you will have to redo all your settings.
if that doesn't work then try deleting the whole documents/Automobilista 2 folder. back up that folder just in case to save you time.

 

Ochilbaz, It's just part of the Antialiasing mode.
If I turn that off it's greyed out.
I have the option to go Application controlled, Off, Enhance the Application, Or Override any Application.
Antialiasing Settings go from Application controlled 2X-8X Super Sampling
Antialiasing Transparency goes from Application controlled, Multisample, 2X-8X (supersample)
It just might be certain cards get certain functions?

 

Thanks for the pointers Steve. After my first G2 failing in the first week of launch last year I've finally bought one again and decided to treat myself to a new PC to go with it. PC only arrived this week but tonight I've played with the settings and OpenVR FSR, as per your posts, and been enjoying locked 90hz with everything on high, steamVR at 100% and per application at 150%. I will play with the sharpness a bit but I'm very pleased.
Not sure if I missed anything but the settings in nvidia control panel, can they be applied to program settings rather than global? Not sure if the changes will matter to non VR stuff.
