Would this work for us oculus folks on RF2 to avoid having steamVR run?

After trying this last few nights it’s WONDERFUL , really appreciate you posting it and MarcG following up on it .

= no stuttering no lag solid fps bigger grids , awesome.

be great if somehow devs could integrate this for oculus & no steamVR

 

[Narrowbackwing]

It would but you don’t get Virtual sound on each side oh headset ( positional audio ) it don’t bother me but until that is fixed I don’t think devs will implement it , and I’m sure it will need to be tested over time , anyway its only a dll file to replace.

I just replace your 64-bit openvr_api.DLL with new download api.DiLL

I tried it briefly and it mostly works for me but
* the view freezes before the loading screen and only comes back when the track is loaded
* I get occasional flashes of different views (too fast say views of what) when driving. It seems to be related to moving my head so I suspect it may be glitches in the head tracking
* I think frame rates are improved
I need to switch back to Steam VR to check my findings.

 

[Narrowbackwing]

Yes view freezes when loading because it needs steam Vr , something I don’t mind , I may be lucky but rF2 looks and runs better than before.

Nice tip, thanks
don't forget to create a opencomposite.ini file in the same directory as the openVR_api.dll,
you can set the pixel density to your liking and some other stuff, like disabling the rifts headphones.

enableAudio=off
supersampleRatio=1.4

I have replaced the openvr_api.dll on rfactor 2 directory, but steamVR still starts, any help on this please??

I think you also need to replace the same file in the bin64 folder (or bin32 if you are using the 32 bit version)

 

[EricW]

Did not test this, but i start it up from Sim commander 4, that points to the startup exe of RF2 in it's install Dir.
so try to start it up from the desktop or install DIR, instead of using the steam client.

For me it's a serious boost in performance Btw!!

That's it!! Thank you!!

My settings .

[/ATTACH]

I just added DLL to bin64 folder , you should also save your new DiLL file if you update , I believe they updated a few times .
Save save save
Edit .
Were do you download.

Its much smoother now to drive with ASW. I noticed less judder. Even under 45fps its now driveable. With SteamVR the judder under 45fps was so horrible that driving was impossible for me. I testet Sebring with 40 visible AI in front of me on the full course in the rain. Shortly after the start a got 45fps with my 1070 with my settings, whats ok for me. My 3770k @4.2 limited the framerate the most time, in dry conditions, my GPU had more headroom.

Im quite sick atm and my brain aint working right !
What are we doing here ? Running rF2 with rift without Steam or without Oculus ?
Whats the easiest way to do this ?
Sorry for being stupid but hey I'm sick .

 

[EricW]

what i understand of it. ..
Normally RF2 uses the SteamVR environment and drivers to make use of a VR headset. Be it a oculus or other headset.
By using this DLL OpenVr will be used instead of steamVR.
Headsets supporting openVR will use their Own drivers to run in openVr.
Get well soon

I think you are right. I tested it yesterday quickly, and working like that (no SteamVR starting with this new DLL, direct communication between Game & VR Headset)

This is a massive improvement. The stuttering is finally gone!
This should be included in the game by Studio 397.

Marcel has stated they are following developments and have helped the developer of this with some info.
I think it's a little early to be talking about including anything in the game, but early testing i have also found positive.
If nothing else, it seems to indicate what many of us have believed in that SteamVR has been holding back performance of VR in rfactor 2 at least for Oculus users.
Let's see how this develops i guess.

Im stupid , could someone make a quick vid showing what they did to get this working please ?
I can get Oculus to not run but not Steam

Just replace the openvr_api.dll in your rFactor, like described in this post: https://forum.studio-397.com/index....hread-settings-tips.55249/page-77#post-962036
An use your rFactor2 normally (nothing else). I have Oculus software running for me.

@2ndLastJedi I found that I had to download the 32 bit and 64 bit versions and replaced both in the relevant folder. Ensure that you 'move' the versions already there [so that you have the originals] before doing this.

Everyone else - the download instructions indicate that on startup, the dll looks for opencomposite.ini, and if not found uses the default settings. The instructions then indicate that you can specify a number of options in this ini file. However, no such file exists on my system. Has anyone else seen this file?
