View Full Version : glPIxelTransfer very slow on Nvidia Quadro4
02-10-2004, 08:35 AM
When I use glPixelTransfer to alter scale or bias in an image on my Nvidia Quadro4 700 XGL, glDrawPixels slows to a crawl. It looks like the scale / bias is being done in software, not in the imaging pipeline. Can it be done in hardware? If so, how?

Update your drivers.
If the functionality is truly not implemented in hardware, then send requests for that functionality to NVIDIA.
According to a colleague of mine, gl*Pixel functions have a history of being slow.
