Hi, im just wondering how do i change my video mode settings? Like instead of OpenGL to Direct3d or something? I cant seem to find it in the program. Any help would be much appreciated, cause when im in Houdini its quite slow and laggy.

Thanks in advance, bye.

Direct3d isn't supported by houdini. Its all opengl. If your video cards not old/knackered try searching on this forum for double buffer. You might have to set an environment variable.
