Hi Anders et al, Since I am the main author of the OsgOculusViewer I will try to answer some of your questions.
First of all, you are not the first user which seem to experience these types of problems. The judder you are seeing have been reported by many Oculus users for all kinds of applications (not just OsgOculusViewer) and can have different origins. Known issues are: * Updates on another monitor may interfere with timing on the Rift and this can manifest as visible tearing in the Rift. This can be eliminated in Windows 7 by disabling Windows composition. * Setting the Oculus Rift as secondary monitor (running at 75 Hz) and having the primary monitor is running at 60 Hz. * On some AMD Radeon graphics cards, multi-sampling may cause judder or what appears to be rapid vibration as you move your head. Try one of the following suggested solutions: * Disable Windows composition * Set the Oculus Rift as the primary screen. * Overclocking the non-Rift primary display to 75 Hz. * Setting the Oculus Rift to use 60Hz instead of 75Hz. I have recently (9th of January) updated the library with support for DirectMode rendering, which may help you. Regarding the fact that OsgOculusViewer uses its own rendering code and not the built in rendering code from Oculus. OsgOculusViewer uses pretty much the same rendering code as in the official OculusWorldDemo, although adapted to use OSG instead of pure OpenGL/DirectX. The reason for not using the Oculus SDK based rendering is that the SDK code path makes some rather broad assumptions about OpenGL initialization order and since OSG uses lazy initialization you will end up with quite a lot of catch 22 situations. I have tried to get it working, but as of today I am stuck with crashes deep inside graphics driver code or inside the Oculus SDK. The code is available at the "sdk-rendering" branch on github, if anyone wants to give it a try.
