Hi, I am experience a massive performance drop when running a 32-bit binary through VirtualGL from my Debian (64-bit) installation. The frames/sec with glxspheres64 are very good and I have no problems so far running any 64-bit binary through VirtualGL.

I have no idea whats causing this massive performance drop. Does anyone have an explanation or any hints for me?
