    AE not recognising CUDA board

    djfilms9 Level 1

      I have a Mac Pro 2012 tower with 2 Nvidia bonds: a GT 120 and a GTX 980 Ti with 6 GB VRAM. Running OS X 10.11.6, with 96 GB RAM. AE has disabled GPU acceleration (see attached screenshot), but the 980 Ti is a standard [and fast] board. AE doesn't even read the board correctly, as it says 2 GB VRAM, instead of the 6 GB it actually has. I verified that the drivers are up to date. Is there anything else I need to do to enable the GPU acceleration?

       

      Any advice gratefully received.

          CUDA is no longer being developed because NVIDIA changed the direction of their development mid stream and the technology never lived up to expectations for Adobe anyway. I would not worry about it and I would not try and use Ray-traced rendering for any paid work because it's dodgy and your projects will take forever to render.

           

          If you want to use Ray-Traced like effects in AE then upgrade to CC 2017 and use the C4D rendering engine. It works a lot better.

            Rick, thank you for your reply. I was hoping that the Nvidia board would accelerate normal rendering (not ray-tracing). I do not want to upgrade to CC... the internet connections here are dodgy at best, so I'm a great fan of working locally and having all my stuff on my computer. Thank you for the clarification. regards.

              CUDA does nothing at all for rendering normal comps. Never has and was not intended to. In fact, if you enable CUDA you can only do so in Ray-traced comps and you loose things like blend modes and effects so it's a loose loose situation at best. The only gain is bending some types of layers and extruding others. That's it...

                Rick Noted. I was in error thinking that CUDA accelerated normal rendering [I use Vray and CUDA makes a HUGE difference]. So i'm stuck with very slow AE render rates, I guess. regards.
