How does the 'CUDA' work?

[치훈이11840303]

Hello ~ Thanks for watching my question

If i choose 'CUDA' when render,

Is it only operated by the GPU?

or

CPU + GPU ( It means 'GPU support CPU )

P.s - I really want to know about that

Because i have 2 PC(1. i7-2600 + GTX1060. / 2. i7-3770 + GTX 1050)

But i need 'PC number 2' as Main PC

If ' CUDA' works by 'CPU + GPU', i'll choose number 2.

The GPU is only involved in rendering in some re-sizing and with the "GPU Accelerated Effects" off the list they have available on the PrPro support pages. It includes most of the color effects like Lumetri, Warp stabilizer and some others.

Where on your sequence you're using the GPU accelerated effects, the GPU will work processing those effects.

Any spot on a sequence that does not have size scaling or GPU accelerated effects will process for rendering/exports entirely through the CPU, and will not use the GPU.

So in general, the cores/threads of the CPU and the RAM are more important for rendering/export than the GPU. As they are always the central resources used for that.

Having a lots of CUDA playback issues (CUDA playback dropping off, black screen after few minutes) with Dell XPS 15 9750 with Nvidia GTX 1050 Ti.  I got it to work reliably with and older GeForce driver (397.93) which I can no longer install because Win 10 64 automatic updates.  The newer GeForce drivers  416.34 and 416.81 (compatible with Win 10 64 Built 17134) have CUDA playback issues with laster version of Premiere Pro CC (Version 13.0.1 (built 13). You can revert your project to Open CL mode which works reliably but much slower export/playback.  Really frustrating with a new machine....

Report this on the UserVoice system ... that way this bug (as it seems) will go directly to the engineer's systems ...

Thanks for the tip. I just did.

After a few tries, the Nvidia installer let me downgrade to 397.93.  All is working well now.  So, buyers of the newest Dell XPS 15 with GeForce GTX 1050 Ti, beware!  Do not update to the latest Nvidia driver versions 416.34 or 416.81.
