Re: [Avid-L2] dual gpu argument for Avid MC on pc vs mac ?

 

Actually gsync is for screen tearing. 

The benefit of sli/cf is upgrade cost. If I have a GTX 670 and want better performance I can either get a more expensive and powerful card, or I can get another GTX 670 for less than the other card. Depending on driver support, SLI can greatly increase performance - sometimes by over 50%, but at least some micro stuttering is always present. It really, really depends on the drivers though.

Parallel GPU rendering (SLI or Crossfire) where primarily designed for
gaming. Micro-stuttering happens during real-time graphic rendering. As
far as I know, CUDA or Open-CL do not support SLI or Crossfire. If in
the future Open-CL supports Crossfire and micro stuttering becomes an
issue, rendering would bypass the issue.

Avid needs a modern GPU dependent playback and render engine. Currently,
there is no support for CUDA or Open-CL.

FYI - Nvidia just released an add-on hardware for monitor manufacturers
called G-sync to address micro-stuttering.
