CUDA Cores not working?

[Ken Mitchell]

Actually to use the Mercury Playback Engine in Premiere CS5.5 you can toggle between CPU and GPU . But if you have a high end Intel CPU you will need at least a GTX550 to improve upon the CPU performance.

I was under the impression that the CUDA cores worked “with” the CPU. If I checked “using CPU if available” the CUDA cores would add rendering power in addition to the CPU.

So what you are saying is that you can render with the CPU or the GPU but not both at the same time?

[William Van] “So what you are saying is that you can render with the CPU or the GPU but not both at the same time?”

Well it’s not very clear. The options are:

• Automatic (Recommended)
• Render using CPU only
• Render using GPU if available

I’m not sure how “Automatic” is different that “GPU if available” which must use the CPU if NOT available. I assume it must use both the CPU and GPU since the GPU can’t be used for everything.

I keep my template set to “Render using CPU only” because it renders faster that way.

excuse me, cuda only for games.

since when. ive not yet once come across a single review about cuda cores being helpful in anyway towards games. yet when cuda cores are talked about its always about rendering and previewing editing content in real time.

cuda cores were brought about saying they would increase rendering much faster than the fastest cpu and these were shown in grapghs by places like vreveal and tmpgenc.

with neatvideo’s l;atest plugin they also claim that it has a significate time reduction BECUASE of the cuda cores it now uses and can take on cards like the gtx 590 and more. so like ive said before cuda cores are more focused on rendering and editing than games from where im reading and watching videos.
