Buckman71 Posted February 21, 2018 Share Posted February 21, 2018 I installed my Vive maybe, a week ago, was working fine with no issues whatsoever untill 2 days ago when I woke up, turned everything on and then it was missing frames like no tomorrow. Runnign SteamVR Home and being in the home environment is fine, doesnt miss a frame, but as soon as I launch a game, or even when I open the SteamVR overlay menu frames get constantly. Nothing had changed from when I went to bed, to when I tried to launch it the next morning, No updates, no software changes, nothing. I know it isn'y my laptop because it was working flawlessly for almost a week and nothing happened until all of a sudden it decides to just drop frames. My drivers are all up to date, there are no Windows updates to be done. Graphics Card: NVIDIA GeForce GTX 980M Processor: Intel I7-6820HK CPU @2.70GHz (8CPUs) 16GB of Ram Windows 10 Context: SteamVR Home only: SteamVR Home with steam overlay menu(Same as with any game open): Link to comment Share on other sites More sharing options...
Synthesis Posted February 21, 2018 Share Posted February 21, 2018 Looks like you have a custom Steam Home environment. Is this the only place you're dropping frames? (Games work normally?)Have you tried changing the environment to the default one or a different Steam Workshop option?Thanks, -John C Link to comment Share on other sites More sharing options...
Dev Posted February 21, 2018 Share Posted February 21, 2018 Hi John, Chipping in to say that after updating to the newest SteamVR build, both of our development machines (identical specs) are also experiencing stuttering in not just the home environment, but in many different standalone VR applications, including the Unity editor. We tested that this does not happen with the previous SteamVR build (by using the second machine's SteamVR before updating it), and regardless of GPU driver version. This is also regardless of which SteamVR settings that are enabled, and we are not using the beta. Curiously, turning the VR dashboard on and then off again in a given scene application fixes the stuttering, but still, this is very annoying and is halting our development process. Is there any way to revert to a prior version of SteamVR? Here is a sample system report from one of the machines: https://gist.github.com/anonymous/4db2bbe811c8e3f0dc70bc02ab3e2e7b Link to comment Share on other sites More sharing options...
Synthesis Posted February 21, 2018 Share Posted February 21, 2018 Unfortunately, no. Have you tried switching to the beta version to see if that helps at all?Thank you, -John C Link to comment Share on other sites More sharing options...
Dev Posted February 21, 2018 Share Posted February 21, 2018 After testing a few applications (and most importantly our Unity build), switching to the SteamVR beta actually seems to have mostly fixed it. There is still some of that nausea-inducing stuttering, but it seems to have restricted itself to loading screens now, so it doesn't happen in loaded scenes anymore. Thank you! Still though, the fact that we could so easily replicate the stuttering might indicate a more pervasive issue in the live SteamVR build. Link to comment Share on other sites More sharing options...
Synthesis Posted February 21, 2018 Share Posted February 21, 2018 There was a massive patch released about a week ago that consolidated a number of fixes and changes for SteamVR. https://steamcommunity.com/app/250820/allnews/You can see some SteamVR beta updates have been released in the meantime as well, though nothing jumps out at me as the possible cause.Thanks, -John C Link to comment Share on other sites More sharing options...
Dreamager Posted February 21, 2018 Share Posted February 21, 2018 I have constant stuttering in home and gaming with the latest beta build when async reprojection is turned on. It works fine turning that off. The whole program seems to lag, even on desktop, with that on. Reverting to the non-beta version everything goes back to normal again.

Synthesis Posted February 21, 2018 Share Posted February 21, 2018 make sure you aren't using interleaved projection and asynchronous projection at the same time. Even though the option is there, it usually doesn't work well. Glad it's working now!Thanks, -John C Link to comment Share on other sites More sharing options...
Buckman71 Posted February 21, 2018 Author Share Posted February 21, 2018 Its actually the opposite, in any Home enviroment im perfectly fine, but its with any game, as well as the SteamVR overlay that causes the stuttering. Link to comment Share on other sites More sharing options...
Dreamager Posted February 22, 2018 Share Posted February 22, 2018 I've had both interleaved and async ticked together with no problems (I'd assumed it'd just choose async if it had it), but I tried unticking the interleaved and it made no difference. It's only unticking asynchronous reprojection that makes it all run 'wonderfully' again. Only in the beta though, fine in normal. Link to comment Share on other sites More sharing options...
