Does anyone know what the performance expectations of glCopyPixels to and from pbuffers would be on Radeon?
We are looking for a replacement for wgl_arb_buffer_region/ktx_buffer_region, which ATI chose to reserve as a “maintain the profit margins of FireGL” feature.
Originally posted by heppe: 9700 or 9800 is what I had in mind. How is the performance relative to reading stuff back into system memory with glReadPixels?
