Poor choppy performance

The Oculus support is poor if you have performance issues on Oculus branded relatively new Alienware computer. About a month ago, out of the blue (maybe after some driver updates), the VR started to pause for about 200ms to 1s. The whole state is obviously not playable; yet, there appears to be no solution. Support team got me jumping through hoops: submitting logs, video clips, plugging/re-plugging, and re-installing, but not making any progress. I wonder how this experience stacks up to HTC Vive?

    What Alienware desktop do you have, and what are the specs? As far as I know, Oculus doesn't "brand" computers; companies like Dell (Alienware) ask Oculus for their approval in labeling their products "VR Ready," and Oculus lets them, if they pass certain hardware specifications. Note that you shouldn't get mad at the company that makes the hardware peripherals when it's the company that makes your desktop that is *probably* at fault. Alienwares for some reason have been popping up in support thread topics much more than I'd like to see them, especially for supposed "gaming" computers.


    TL;DR - If your alienware is giving you trouble, I would send it back to Dell for a replacement

    Alienware does not give me trouble in Battlefield 1. Also, Oculus was working just fine for the first 2 months, but it is choppy now. My desktop is Aurora R5:

    Did you install anything recently that might conflict? Anything that overlays or modifies the screen can cause problems, such as GPU monitor apps (MSI Afterburner, RivaTuner, F.lux), remote desktop applications, screen sharing, etc. I'd also see if it could be an anti-virus / security software conflict. You can try temporarily disabling anti-virus. I could also be a USB driver issue. Either update your USB drivers to latest or (if that doesn't work) uninstall and use Microsoft default. Hope that helps.

    Thank you! I haven't really installed anything new, but the drivers might have been updated. The strange thing is that it runs smoothly for 10 min and then starts to have the intermittent tracking problems. The device seems a bit warm to the touch at that point.

    That sounds like thermal throttling (maybe cpu, maybe gpu) due to overheating. See if you can find some software to test temperatures. Maybe a fan's jammed / blocked / running slow.

    Thermal controls from Alienware do not seem to show any heat on GPU. It looks like the Rift goes back a frame and then jumps to the appropriate position. This could be something wrong with gyros because the stutter is independent of sensor tracking.

    The tracking issue seems to have started with last Oculus update. whilst in the "lounge" , without moving my head, the image "jumps" a little. then a pause and another jump. it seems to be continually. The issue is evident in all of my games. If you choose VR MODE in steam - whilst in the grey room - the sensor seems to lose contact intermittently. I have the latest drivers and connected to USB3. nothing has changed hardware wise from before the issue started. Have restarted, reinstalled Oculus and gone through the setup procedure. Pretty much done everything to try to solve it.

    If you're talking about your headset being warm, that's normal. So, the issue is; around 10 minutes in to gameplay, you get tracking loss for 200ms up to 1s at a time?

    And have you checked CPU temps? Tracking loss would be more of a CPU thing than GPU.

    DongOculus, exactly the same issue from the sound of it. The reinstalls have not helped me either. 
    CPU temps look OK, 44C. The tracking loss is for about 100-200ms.

    DongOculus and sergiy, that sounds pretty much identical to the tracking problems I was having. In my case reinstalling oculus seems to have fixed it, at least for the time being. My problems also started after the last update, no changes to my PC were made before the problem started.

    FIXED!! ..   a guy was having trouble with his Vive. He posted a video and bingo! Go to your motherboard makers website - mine was ASUS - and update your USB drivers. Ensure the USB3 drivers are correctly installed. worked for me anyways :)

    Not fixed ... I've updated all the USB drivers just in case. No change in the choppiness. It has been now about 2-3 months with this issue. The support from Oculus is by far not stellar. I can't imagine the same level of problems with any other device and no solution or replacement for months of working with them.

    Are you running Avast anti-virus? If so, remove it. It caused a lot of trouble on my PC.

    Nope, no Avast, just the regular Windows 10 Defender.

    Oculus people are now asking me to make pictures of my setup. :) They are lost or dragging their feet ... It has been over a month of talking with support with a couple dozen messages, making movies through my device, running logging apps, reinstalling Oculus, updating all sorts of drivers, sending receipts, pictures of the device, QR code on the device, and even checking that I have a current credit card associated with them. I can't imagine what they would have done if this device were in my mom's hands!
