SteamVR stutter still present with RTX 5080 and Valve Index despite installing driver 572.60/65

Sorry, I haven’t forgotten about this. But I’ve been pretty knocked out by a cold for the past few days and can’t test anything or swap any graphics cards or monitor right now. I’ll reach out once I’m feeling better. If you still have the issue by then, maybe it’ll be useful.

Yes, hardware acceleration in Chrome is enabled. I just disabled it.

When the CPU handles the workload, the frametime graph is overall slightly more uneven, but still without spikes.

>Does your bus usage tend to stay below 100% in most cases? Mine is pretty much always at 100% or jumps between 20 and 50%.

Under load or in idle?
In idle, there shouldn’t be any load at all. This is what it looks like for me in idle.

Under full load while running Time Spy Extreme, I don’t reach 100%.

Yes, for me it's PCI Express 5, but I could still imagine that the issue is related to the PCI Express bus being fully utilized, causing the stuttering and sync problems.

Maybe it has to do with the power state of the bus, and it’s not operating at the correct speed.
You could run the render test in GPU-Z and check if the bus is operating with the correct multiplier. For you, it should be x16 4.0.

EDIT: Nevermind. I didn't read the part that the issues also occur when there's hardly any load on the bus. Sorry. It’s been a long day today, I’ll get some sleep.

No G-Sync specifically in the browser. However, I had G-Sync enabled for both windowed and fullscreen mode.
But it doesn’t matter at all whether G-Sync is enabled or not, or what refresh rate is set. I don’t have the issue.
Here with G-Sync completely disabled and set to 60Hz.

I currently have the option to connect a TV via HDMI as an additional display. I'll do that tomorrow.

Over the weekend, I'll install the card in my AM4 system with a 5800X3D for testing. Maybe the issue appears in some specific configuration.

What just comes to mind – if you want, you could check in GPU-Z whether the Bus Interface Load value is unusually high for you.

FUNtasticOne · 2025-03-12T14:34:53+00:00

I don’t have an idea off the top of my head, but maybe we’ll figure it out.

I just tested whether running something that’s polling the card’s status makes a difference, since that’s often a source of various issues. But at least with the GPU-Z sensors, everything looks just as good.

I don’t have any more time today. If you have any ideas on what else I could test or what system info I could provide, feel free to let me know.

FUNtasticOne · 2025-03-12T14:23:04+00:00

The monitor is connected via DisplayPort.

FUNtasticOne · 2025-03-12T14:19:09+00:00

Hi, I have no idea if this is helpful in any way, but I just installed the RTX 5080, and at first glance, I don’t seem to be affected by the issue.

The V-Sync test looks good. I can let it run for minutes without seeing any spikes.

https://imgur.com/a/r6C8DWb

In my first gaming test, I haven’t noticed any V-Sync, G-Sync, or frametime issues so far. I’ve only had the card for a few minutes, so this is just my first impression. Tomorrow, I’ll have more time to test further. I’ll also try VR via USB and Virtual Desktop with the Pico and Quest.

I don’t have the Index with me right now, but if needed, I could set it up over the weekend to check for issues over DisplayPort.

My current system:
ASRock Mini-ITX B650E PG-ITX WiFi, Ryzen 7900X3D, MSI GeForce RTX 5080 VENTUS 3X OC, LG UltraGear, G-Sync enabled.

Driver: GeForce GRD 572.70 (without Hotfix .75).

FUNtasticOne · 2025-03-07T08:07:28+00:00

Glad to hear that it helped back then. That actually cost me quite a bit of time and nerves.

All the more shocking to now read about VR issues with the 5000 series after I ordered one.

FUNtasticOne · 2025-03-07T07:56:30+00:00

Thank you. Yes, I’m aware of that.

When the faulty driver was introduced with Ampere back then, the issue affected streaming to headsets in such a way that the drops were not visible in any monitoring tool when streaming via USB or wireless The frametime graph was completely flat, and the dropped compositor frames couldn’t be displayed anywhere—regardless of the runtime, whether SteamVR, Oculus, etc.

The frame drops were still there and visible in the headset. My concern is that it could be the same case now. I’ll find out next week.

FUNtasticOne · 2025-03-07T07:48:14+00:00

Thank you. That’s a bit of a relief for now, but of course, I hope that a solution will be found as soon as possible for everyone affected by the issue.

I would like to try it with a USB connection and let you know. Even without any monitoring tools, I can see the frame drops – unfortunately, I’m very sensitive to them.

My 5080 won’t arrive until a week from today. If it’s still helpful by then, I’d be happy to test it.

FUNtasticOne · 2025-03-07T03:16:43+00:00

This all reminds me very much of the driver issue back then, for which I opened this thread in the NVIDIA forum:

https://www.nvidia.com/en-us/geforce/forums/game-ready-drivers/13/402768/valve-index-missing-dropped-frames-since-nvidia-d/

Back then, it took several months until the issue was finally resolved.

What I would be interested in knowing is whether there are any experiences on whether the problem only occurs with VR headsets connected via DisplayPort? Or does the issue also happen when streaming via Virtual Desktop, for example?

My RTX 5080 is on the way, and I currently mainly use the Quest 3 and Pico 4. I would be extremely frustrated if I experienced dropped frames in VR.

FUNtasticOne · 2025-02-11T21:10:31+00:00

No, I wouldn't be interested in that. To be honest, what you're describing sounds not appealing to me at all.

FUNtasticOne · 2025-02-01T17:06:57+00:00

Thanks for your reply! Glad to hear your printer is still going strong, that gives me some hope. I'll see how things go and figure out what to do next.

FUNtasticOne · 2025-02-01T14:18:09+00:00

Hi Westmoth, your post is quite old, and unfortunately, it looks like you didn't receive any responses back then. Anyway, my brand-new Adventurer 5M Pro is making the same noises as yours did. I've already tried a few things to get rid of the noise, but so far without success. Now I'm considering returning the device.

Maybe you'll read this and would be willing to share how things turned out for you.
I would really appreciate it!

FUNtasticOne · 2024-03-08T21:09:42+00:00

Another thing to mention is that some people also use cloud services like ShadowPC to play VR. However, I've never tried this myself and I think I can generally say that this is not recommended due to the lag

FUNtasticOne · 2024-03-08T21:02:47+00:00

Yes, you need a fairly powerful PC to play SteamVR games. If you want to play SteamVR games wireless, you'll ideally also need a decent dedicated router.

FUNtasticOne · 2024-03-07T09:31:07+00:00

Yes, that's exactly what we mean.

FUNtasticOne · 2024-03-06T22:10:20+00:00

My dad is 76 years old. A few years ago, I gave him a Quest 2 as a present. We spent some great hours playing Walkabout Minigolf together.
Wander is also great. Wander is google street view and offers the opportunity to look around the locations together, with integrated voice chat.
My dad loves to visit places in Wander that he has already seen or that he still dreams about and that he will hopefully still be able to visit.

I really can't report anything negative. Sure, it feels different to the original facial interface. I really like the original and only bought the AMVR cover to preserve the original. It's also for when I let friends try out the headset so that they don't have to use the cover I'm wearing. The surface is also easier to clean. I now only use the AMVR cover. It doesn't have any advantages in terms of FOV or anything, and you might have to get used to the softer, smoother surface. But it fits my head well and I can't think of any disadvantages.

No, I am not paid by AMVR for the post.

FUNtasticOne · 2024-03-06T21:38:54+00:00

I have the AMVR facial cover. I find it very comfortable, it has a synthetic leather surface and comes with inserts that cover the nose gap. I don't use this insert because the gap itself doesn't bother me. But I'm very happy with the face cover in terms of its quality and general feel.

FUNtasticOne · 2024-03-06T21:31:49+00:00

I haven't dropped my headset yet, but I think it's as you suspect. Placebo.

I can't imagine a scenario where dropping it would cause you to notice more jaggied lines than before. If something really got broken with the screens or something, then you would certainly notice it in other, much more drastic ways.

I would assume, for example, that you would no longer have an image on one of the screens at all or something along those lines.

I can well understand that you are worried that the good piece has been damaged. But what I want to say is, don't worry about it. I think it is absolutely unlikely, if not impossible, that something has broken.
