Huge FPS Drop when switching from debug mode to real Rift
Hello everybody,
I'm new to this forum and I hope you can help me with my problem.
I'm currently developing an openGl based VR viewer for huge Pointclouds.
I've done a lot of testing in the oculus debug mode, now testing with the real rift I'm having a huge performance drop.
Depending on the number of points I have easily 75Hz. With the Rift plugged in I can easily see it stuttering while moving the head.
Has anybody an idea, where these problems come from?
any help is very welcome...

- Anything less than 75 fps, and you will see studder
Maybe you are not computing the fps correctly.
Do you see studder when you run the Tuscany demo? - the studder was just while moving the head, kepping the head still and moving the view with the mouse was perfectly fluid.
I solved the problem now. In first step I don't have any problems in direct mode, just in extended mode (find this out on a nVidia sytstem). Direct mode wasn't working on my AMD system in first step. Switching to 64bit solved this issue, too. So now direct mode is working on my system, too and I don't have any studder in direct mode.
So I'm fine now. But I really would like to understand that issue, maybe somebody can explain it?
