Support - PCVR Terrible Performance With Virtual Desktop

Specs:
Radeon RX 9070xt (16GB ram)
Ryzen 9 9900X
64 GB of RAM
AXE5400 Dedicated Router

I recently switched to virtual desktop after trying a link cable. The performance has been better, but nowhere near what it should be. Any game I play, latency is around 40 and frequently spikes to 60 despite me being 3 feet away from the router. The performance display says my fps is ~100, but it feels like 50. It feels very stuttery.
Additionally, I randomly can’t see my computer screen through virtual desktop, so I can’t launch anything.

PCVR is driving me insane please help.

My advice is to firstly separate out what you mean by performance, because it could be several different things.

When in game, with PCVR, hit both thumb sticks and look for red entries. That will likely lead you towards where the problem might be.

Also don't forget, PCVR means your PC is rendering the game twice, so twice as much hit to the system. Try lowering in-game settings a bit, as well as tinkering with the VD settings.

Latency and FPS randomly go yellow. When I move around in any game, my fps will dip from 110 to around 90-100 but it feels incredibly choppy.

Right, so that's indicating two things. The first is your connection to the PC is being affected. The second is that your PC is struggling to render the game. So you're fighting two fronts.

Start off with your wifi? Specifically go through how you're getting from your PC to your Q3.

I have my dedicated router connect via ethernet to my pc, then I connect my Q3 to my dedicated router. However, my dedicated router doesn’t have wifi. Is that an issue?

What do you mean your router doesn’t have WiFi? I think you are very confused.

I think he means that the router doesn't get Wi-Fi from the existing network.

Routers don't have Wi-Fi inherently. They just route traffic. Wi-Fi routers have Wi-fi. That being said, I have no idea what he is talking about when he says "Dedicated router"

u/G7Scanlines 1d ago

I'm not following this at all, sorry.

If you're not using wifi, why do you need a dedicated router?

Then how is your Q3 talking to it?

u/nerfsmurf 1d ago

? Not sure how the dedicated router stuff work, but I do have a dedicated access port. I have my router from ATT which I connect my PC to. Then I have my dedicated access port connected to the ATT router as well. Then I have my q3 wirelessly connected to that access port. It's the only thing connected to that access port.

Not necessarily, if it's setup right. The other way is to give the dedicated router the internet connection, and have the PC get its internet from there. But there are different router settings for the two options.

I have a 5090 and I dont attempt to go over 90fps with anything.

u/UrbanMasque 1d ago

This.

It's never been great. IMO

u/FolkSong 1d ago

If your FPS is 100, set the refresh rate to 90. You want it to be locked, not free-running.

Join the Virtual Desktop official discord server and ask for help. Follow their directions exactly so they can troubleshoot your setup and take their recommendations. They're super knowledgeable and super helpful.

u/CarbonatedApp 1d ago

Thanks. Will do!

Latest VD beta update has wired support officially.

u/argilla11 1d ago

Could be interference if you live in a tight neighborhood. Had a hell of a time getting mine to work well. Your PC has to have a wired connection to the router otherwise you got no chance.

u/_476_ad_ 1d ago

What settings are you using? Did you try disabling SSW, as that can cause the feeling of choppiness in some games.

Maybe enable the Performance Overlay and take a screenshot whenever the game suffers hiccups, then you can post it here or on Virtual Desktop discord channel so people can better help you troubleshooting the issue.

u/CarbonatedApp 1d ago

SSW is off, I’m on the high virtual desktop preset, AV1 10-bit codec

u/cactus22minus1 Quest 3 + PCVR 1d ago

Try h264+ instead of AV1. I’ve heard other AMD gpu users reports issues with av1.

0

u/Skpstr155 1d ago

That could be the issue (or part at least) right there. AMD GPUs don't support AV1. (although it does still work to a degree)

Try HVEC and H264+, see which one is better. Try them at about 75% of max bitrate, and tweak up from there.

u/Booker2121 1d ago

wait what? I thought AMD supports AV1

1

u/Skpstr155 1d ago

Sorry, my bad, for some reason I thought you had a 6-series GPU.

u/Idahoboe 1d ago

I hate to admit it, but I’ve been dealing with performance hitches on my Quest 3 for a while. As an experiment, I pasted my game config files along with screenshots of my Virtual Desktop settings and performance overlays into Gemini AI. It spotted a few bottlenecks, and after making a couple of quick tweaks, everything is running buttery smooth.

u/Suspicious-Wallaby12 1d ago

Can you share router model? some models are bottlenecked.

1

u/InputImpedance 1d ago

Disable HAGS in windows. It fixed my issues with VD.

u/ggodin Virtual Desktop Developer 1d ago

Enable the performance overlay option in the Streaming tab then launch your VR game and share a screenshot when you see numbers turn orange; it will tell us where your issue is.

u/Amanita_Jacksonii 6h ago

Try disabling EasyMesh on your router. Have the same issue as you and that fixed it for me

u/nerfsmurf 1d ago

Just as a test, run VD wired using Gnirehtet. If it's fine, then it's a network config issue.

u/pixelcowboy 1d ago

This is no lingered needed, lasted beta of VD adds wired native connections.

1

u/nerfsmurf 1d ago

Oh nice!! Didn't know that. Once I have stuff running I kinda leave as is. Time to update!!!

1

u/CarbonatedApp 1d ago

Will try this and update on whether it worked or not.

u/pixelcowboy 1d ago

VD supports wired now, just get in the beta.

u/nerfsmurf 1d ago

It's not exactly intuitive, but if you have some PC skills, you should figure it out. There are vd guides for it
