    AMD HD6970 Slow or Cuda vs OpenGL

    M4uri

      Hi,

       

      actual i use a Radeon HD6970 Gfx Card,

      but if i'm trying to render a video in after effects cc its painfully slow and just uses the CPU instead of the GPU.

       

      I know that CUDA comes with nvidia cards but as far as i understand is OpenGL the equivalent to Cuda so

      i dont understand why i cant choose GPU here:

      if openGL is an equvivalent to cuda, why cant i use it ? do i realy have to buy another gfx card to use the GPU ????
