Getting stuttering/juddering when looking left/right? Was perfect a few weeks ago!?

[NeilTheNameless]

So trying to use the Rift today I'm getting quite obvious judders/stutters in the rendering as I turn my left left/right.

I've tried Steam VR, and a number of Oculus titles, and around the front 90 degrees as I look left/right I can see every now and then the scene stutter as if the sensors are getting confused?!

I've recalibrated the sensors numerous times. Tried moving them slightly. Tried moving one of the sensors to a USB 2 slot. Tried moving the HMD to USB 3 slot on the MB. But nothing seems to help!? They're minor but enough to put you off, and certainly nothing I was having before!

Any idea how to diagnose the cause of the stutters?

Note: Both sensors and the HMD were all in the Inateck 4 Port PCIe card which I'm sure was working fine until a couple of weeks ago!?

I'll give you some some tips to get the games running smooth again. I did this for Onwards and it fixed my problem for that game. I'm not sure what fixed it though.

1) Installed the latest Nvidia driver.
2) unplugged my sensors and ran the whole Oculus setup again.
3 Stopped Malwarebytes starting with window and reinstalled Avast free and put it in silent mode.
4) stopped the killer network thing from starting and any other unnecessary programs from starting with windows.
5) reinstalled Onward.

Job done, fixed Onward from having serious stutters and rubber banding. I also used Oculus debug tool for SuperSampling instead of Traytool. I can't say which one of these was causing it.

All of what’s listed works for you lovethis, I’m glad it had and thanks for posting here. But this seems case by case. The problem is there are so many variables and hoops we must jump through all the time just to get the standard Rift software running without performance issues of some sort. Ultimately the rift software needs to be more versatile. They need to put in the work to make this right for everyone on every PC with every set up or they will sink.

@UBSERD - I agree, but if it's something unique to your computer then Oculus cannot fix this. Oculus logs only tell part of the story. The main culprits are your Games, the Oculus setup or Nvidia drivers. I would always suggest fully reinstalling the game to start of with. I would then do a clean reinstall of the Nvidia graphics driver and not just an update. I would then go on to fully reinstall the Oculus Rift, just like you would if it was a printer that went wrong or any other device for that matter. That includes removing the sensors from their usb ports. 

I would then look at anything I had done or changed on the computer and look for any Window updates that might have caused the problem, or look to see if there are any background programs running that are causing the problem. If none of the above worked, then I would put in a support ticket telling them you had done all the above and I would include your logs. I did most of what I've mentioned above and this fixed the Onward game. I'll test my other games later and get back if there's still a problem.

Thanks for the reply @lovethis. The one thing I haven’t ever tried was unplugging the usbs before installing. Do you do that for the sensors as well as the rifts usb and hdmi?
If so will there be on screen prompts to plug them back in one by one?

Oh also for the Nvidia uninstall do you mean going into device manager right clicking and uninstalling the gpu, then restarting the pc to automatically let it download again. I’ve done that before, but I’m not sure if that is the method you’re speaking of. I’m sorry I’m not the most tech savey in the world.

@UBSERD - I just run the Rift setup like it's a new setup. I also plug the sensors into different usb ports. Just switch the ports over on the two sensors and this will refresh the usb port for the sensors. If you use a 3rd sensor try it in a usb 2.0 port as that is what's recommended. For the Nvidia driver I just opt to do a clean reinstall when I've downloaded the driver from the Nvidia site. I don't choose the option to save my Nvidia settings, I just click the option to do a clean install of the Nvidia driver. Link me to your problem and I'll see if I can help. I'll look to see if I can find it in your posts in the meantime. 

Was everything working fine for you at one point? And at want point did it stop working fine? Are you getting juddering in games or just in one game? What is the problem exactly?

This can usually be a software conflict. I recall hearing issues with the newer Nvidia drivers (I think 388.00 is the most solid newer driver). It can also be conflicts with applications like Asus AI Suite or Asus Sonic Suite (must be uninstalled) or MSI Afterburner, RivaTuner, F.lux, TeamViewer or other apps like GPU monitor/overlay, screen capture or modification (these can be disabled or closed). As always, feel free to submit a support ticket if you need assistance. Thanks.

@lovethis I'm getting problems in all games. It used to run perfectly at one point for 3 months of the 12 plus I've had it. Every game was flawless except games that needed optimization from the dev at the time. I always do everything you mentioned regarding Nvidia installation but I usually save the setting instead of doing a full reset. I’ll take a photo of my settings before I delete it and see if reentering them will change something for the better. Thanks!

@cybereality thank you!  I don’t have any overlays though. I will try the 388.00 again but have gone through all of them since July and it’s always the same performance. I can play PC games at top settings with 60+ frames a second no problem. I know this is a different animal but it shows you that my PC isn’t really running poorly it’s just running Oculus VR poorly for some reason and I or my computer tech can’t even figure it out. He had my rift for about three weeks straight at one point constantly troubleshooting with oculus support and they couldn’t help him figure out anything that could be causing it.  I will continue to plug away I guess. Thanks for the response.

I had the same problem. Check out my post history. Went back and for with support forever. Tried every possible thing. One day it magically stopped stuttering. Ran good for another few months and the stutters came back around end of summer... Definitely some kind of software/firmware conflict.

Interesting.  I used to think it was just me. I’m glad to see that people have had the same issues. It felt really lonely on the bottom with no hope. I can always take my PC back to have him redo the whole thing again but it never helps. I’ve refreshed my PC about 10 times and out of nowhere it’ll just start working again perfectly. I wish oculus had a diagnostics tool that could read your entire PC for problem programs for the Rift and give you a diagnosis of what needs to be deleted or disabled. That would be really cool!! It just sucks to do a lot of legwork to get this thing running and I really do troubleshoot this every day and only occasionally play my games because when I do they remind me how bad it’s performing and makes me sad.
