when using CUDA, is Using renderbuffer as CUDA surface and rendering using glBlitFramebuffer normally better than Using OpenGL texture as CUDA surface

which is faster and more efficient?

  1. Using a OpenGL texture as a CUDA surface and rendering on a quad (new style);

  2. Using a renderbuffer as a CUDA surface and rendering using glBlitFramebuffer.

Solution

  • It depends too much on the hardware, driver version and internal formats of screen and buffer.
