No sRGB inside HMD (OpenGL, SDK 0.4.3)
Hello, Here is my experience with the DK2 so far. I work with SDL2, OpenGL 3.3 in default profile (compatibility ?) and Windows 7 64 bits for now. I was surprised to get the Direct HMD mode working...
There are some (different ?) performance problems here and there for now. Some have sometime abyssal performance (way below 1 fps) like I did with 0.4.3. I now only create a window (not fullscreen) for direct and extended mode and I don't have this problem anymore. It's also the only way to make things work fine on computers with lower resolution than 1080p.
jspenguin (thanks a lot for the SDK DLLs !) also reported a fairly high cost of the function ovrHmd_EndFrame() especially since 0.4.3. An Oculus dev explained that they actually use 2 sync points to reduce latency, and that can hinder performance somewhat. Better solutions should come in the future. But with V-Sync off, I can't have more than ~160 fps with a spinning cube :( (okay, Core 2 Duo, 9800 GTX..., but still, not much room for nice graphics).
