I have a pbuffer. Before rendering to the pbuffer I do the following: glBindTexture(); glReleaseTexImage(); wglMakeCurrent(hpbDC, hpbRC); After rendering it to the pbuffer I do the following: wglMakeCurrent(hOldDC, hOldRC); glBindTexture(); wglBindTexImage(); This runs great on NVIDIA QuadroFX 3400 PCI Express with 70.78 drivers. This terribly slows down on NVIDIA QuadroFX 3000G AGP 8X with 70.78 drivers. It slows down during context switch but slows down significantly for wglBindTexImage(); Anyone has any clue, why NVIDIA QuadroFX3000G's do that ? Solution:- Even though the drivers are the same the hardware does not support floating point pbuffers. [Edited by - dimensionX on March 9, 2005 5:19:49 PM]
