VR Discussions, Questions & Feedback

So when setting the particles setting from ultra to medium you can gain a lot of FPS in VR.
Does anyone know what you exactly lose when you do this? Is it only the amount of rendered particles (less dense smoke?, less sparks?, less raindrops?…) or do you lose certain effects completely?

 

Thanks for all this! I'm going to get a new router. While I'm waiting I'm switching back to the link cable, Do you know what I need to do to have opencomposite work with the cable? I can't remember the command to type in the launch instructions in steam.

 

Hello VR-guys. What is this VD and opencomposite thing all about?

Since the early days of VR I always only use my VR stuff (Oculus/Meta) "normally" without any extra steps. That means I connect my Quest 3 via Link cable to my PC and start AMS2 via Steam (Oculus mode).

The only "extra thing" I do to gain more performance (FPS) in VR is to narrow my FOV in the Oculus Tray Tool but that's it.

Would you suggest that I should try to fiddle with the "other things" (VD, opencomposite) and would it really be a step forward or would it only be a few FPS more but with compromises like less picture quality for example (like using DLSS or Framegen in 2D-games)?

My reason for using Link-cable is also to not having to worry about battery life (via Cable my Quest 3 gets power from my PC, unplugged via Virtual Desktop I would have to stop when my battery is empty, right?).

Whereas here in AMS2 I can achieve fluid 72 FPS (I use the lowest Hz-setting for my headset and a narrow FOV in TrayTool) and maybe therefore wouldn't need this "opencomposite-thing", in MS Flight Simulator 2024 I really have problems in VR to get fluid gameplay with acceptable FPS... Maybe at least for this other VR-game it would make sense to learn something about "opencomposite". Is it really the "wonder-thing" when it comes to VR-performance?

Thank's in advance for helping me...

 

I'll start by saying I don't really know - I'm sure others will explain, but my brief experience with a Oculus quest 2 was borrowing one to test it to see if I thought it was worth upgrading my rift S yet - and I just used it like you have. Thought it was much better and then handed it back. So I don't think you're missing a lot but maybe wait for other opinions from quest users.

I do it the same way you do. For me it's not really worth the effort to bother with the configuration every few weeks. It happened more than once that either one or the other received an update and required hours of configuration. The absolute biggest performance increase for me is the Fov. But I'm not a professional either and I'm tired of these hand in hand programs. I don't have much time so I want to drive in the car and not go crazy. For me it's easier in the long run to change the resolution or Fov.

 

I can't feel any loss in visual quality in medium from high. Just much more FPS.

 

In MEDIUM works like It suposed to be, LOW is terrible.

 

Set it up the same as for VD. Then launch in Steam, selecting the Start in SteamVR option.

 

IMHO if you are happy, then stick with what you have. VD is just another option which allows you to go wireless and drop the cable. It also has some high requirements meaning a good router and direct cable connection from said router to your PC, which can be a problem depending on location of your router and PC.

OpenComposite is for using OpenXR in games that don't have it available, like AMS2. MSFS has OpenXR natively so you wouldn't use OC anyways. Most people use OC in AMS2 so they can use the OpenXR Toolkit. One thing to note is that OpenXR Toolkit is no longer being developed and at some point in time will break. I personally don't use OC or OpenXR Toolkit.

Edit: for anyone wondering what VD is, it is a separate software application called Virtual Desktop, not a disease.

 

My Vr is terrible compared to what it was before. Update is good but vr worse than before for me

 

Game is launching in SteamVR mode. I've used the modified, opencomposite ini AND switched to the original ini file, launches w/SteamVR. Is there anything I need to type in the text window where you select the launch method in Steam? I recall having ~VR or similar previously.

 

No, just put the Oculus Bypass dll (LibOVRRT64_1.dll) in AMS2 folder and OpenComposite dll (openvr_api.dll) in AMS2/x64 folder, then start game in SteamVR mode and you will be running in OpenComposite.

I should have mentioned that I play with link cable without virtual desktop. The option in AMS2 menu is not there for me. I can navigate the menus moving my face but it is not so ideal

 

You have to be careful with the 47 cars. If I stay at 20 it goes well. But I think we still need to test further. If it was already running at the limit, 1.6 can cause the performance to collapse. (Rtx4070, 32gb, amd 5600x)

 

Did that, so it's running in OpenComp even though SteamVR is running when I quit the game?
Also to switch back between Virtual Desktop and Link I just start the VD Streamer select VDXR as the method in that, and "SteamVR" as the launch method in Steam and the game will start using opencomp in virtual desktop, correct?

Sorry I'm a bit thick on this but there seems to be something that has changed since I implemented this before. I think I was using the system-wide opencomp program that doesn't seem to work anymore.

 

I never use the system wide OC app. DLL is simple enough and really no need for updates.

I can't recall if SteamVR still runs when using a cable. You could install OpenXR Toolkit to see if it works. If it does then you're in OC. Really can't think of another reason to use OC if not using OpenXR Toolkit to be honest.

Yes, when switching back to VD, just select the VDXR codec and start the game from the Games Tab in VD and you should be all set. You can test that now with performance monitor up to see if it displays VDXR+OC.

Edit: I prefer SteamVR because I really like fpsVR app.

 

OC gave (me at least) better performance than running through SteamVR. I don't think OpenXR Toolkit works with AMS2. I need to choose a path and go with it before I die in settings hell. Thanks!

 

There is no end to adjusting settings in VR. It's a never ending battle. We're all convinced "there's more to gain". Just ask @Ernesto_171 , he knows all too well.

 

I believe I reach the Sweet Spot now, for 90 stable FPS in any track/cars/no headlights/any weather, keeping really nice visuals. Will soon all settings for Quest 2.

Headlights? I give up to ASW, but as It only kick in now raining or low light, don't bother me even in 45FPS stable.

 

I should be so lucky….I’m racing with 10 visible cars lol. My specs are in my signature. I think I will wait until someone can post up definitive settings for quest 3

thanks everyone
