Recording pointcloud - major frame drops with HapQ

Hi! I have got some problems recording the pointcloud from my kinect. Im using the hap q codec since the animation codec gave me a terrible framerate.

I used the glsl code from this example for recording the point cloud

I also used the pack TOP for packing my 32-bit floating point Pointcloud texture into a larger 8-bit. But it gave me a very bad picture thanks to the compression I guess.

Are there any better approach recording a pointcloud from kinect then these two approaches?

In the attached .toe file the two top base are for recording and playing the pointcloud generated with GLSL

The bottom one Im using the Pack TOP

Thanks
