If so, top tier support for the particulr card using the ABI for OpenGL may be able to tell you whih ibrary entrypoint is the cruxm, which can then be replaced with a custom routine, if you really need it. Normally with a high end cardm the rutines should automatically kck in.
If possible ty a step forward to ultimate Beta, then a step back to earlier cversions of the car ddriver and any ABI in the graphics area (OpenGL, J, etc.) you can get to; se if any combination gets a higher rate out of the card; because you may uncover a valid driver/ABI library bug causing a failure of one specific routine with a fallback to a generic running at a much slower rate.

It should be automatic -- it's an API designed to drive hardware. It's possible that some implementations of off screen rendering do not use the GPU. (This would mean that some systems benefit from hardware acceleration with off-screen rendering while others do not, even though both contain hardware which could support that rendering.) That said, until someone finds a solution, there isn't much benefit in trying to describe that solution. -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
