Performance in VR suddenly very bad
Hello,
since a little while ago some VR applications run very jittery on the Oculus as compared to normally.
Background Info:
I am developing VR experiences in Unreal Engine and so far they all ran very well on the Oculus, noticably smoother than on the Vive. But now the same applications are very 'jittery', now much worse than on the Vive and I don't know why. I am using packaged VR projects to trouble-shoot this, so these applications have not changed between 'all good' and now.
More Details:
First I tried all sorts of things within UE as I thought it was to do with an update from 4.15 to 4.17. But as the tests with those existing applications showed it must be related to something outside of UE (I guess).
The 'jitter' is mainly noticable when turning the head. It looks like linear movement and teleporting are ok, but it's hard to say as I can't keep my had still when trying to do a strictly linear motion :-)
Therefore I looked at ASW for a bit and tested the different modes (ctrl+1 / ctrl + 2 / ctrl + 3 / ctrl + 4) when in-game but that did not really make a difference.
Also, in some applications the jitter only starts after a few seconds.
Testing the same applications on two other machines suggests that it is a PC-specific issue: On one high-powered machine the application runs smoothly and also on a just-above-minimum-spec PC it runs quite well.
I found performance profiling within UE and using the Oculus tools very hard to get familiar with so I do not have any valuable information from that at the moment.
VR games (Arizona Sunshine and Robo Recall) seem to run just fine.
Do you have any suggestions for how I should go about fixing this issue? I don't know what to try next.
