I noticed CUDA was not selectable under project settings inside Premiere 2020. So I un-installed and re-installed the latest NVidia drivers. CUDA started working again. However, after working for a while ... CUDA stopped working again.

I am hoping someone here will have some insight on how to correct this. If you do ... Please share it here.

Windows 10

128 Gig Ram

3.4 ghz 14 Core CPU

(4) NVidia RTX 2080 TI's

Thanks!

Understood. Wish I had something to offer, but ... I ain't no engineer.

So, what other apps do you work in that four 2080 Titans are worth having around? That's a lot of spendy and wondrous fire-power ... something more like my colorist friends might have.

I do a lot of 3D and Motion Graphics. My 3D apps take full advantage of all 4 GPUs for rendering which is exceptionally fast in this setup; Like having my own small rednerfarm. I mainly stick with Redshift 3D for rendering which is ridiculously fast. Having worked in feeature films I am impressed with it every time I render.

Sadly, Ann may have a point. Premiere isn't that good at working with mulitple GPUs. And I know a number of colorists with rigs like yours, that some other apps use well. I do know SLI connections often seem to bother Premiere.

But understand ... the CPU/RAM subsystem is the heart of processing in Premiere. It uses the GPU only for effects on the GPU Accelerated Effects List such as Warp, Lumetri and some other color effects, and major re-sizing.

For those things, Pr sends stuff for the GPU to work on as the CPU gets to things. So the GPUs are always waiting for the CPU to send them stuff.

> Premiere isn't that good at working with mulitple GPUs.

Unless something has changed over the past few years, that's not correct. Premiere is exceptionally good at scaling across multiple, independent GPUs. In fact, it's stunningly good at it, as we all learned with the Premiere benchmarking. What does throw a monkey wrench into that is SLI'ing two of them together. The only issue there is that Premiere stops seeing two GPUs and only sees one. And only uses one. It otherwise works fine.

But, our OP has four, and NVidia has long-since gotten rid of > 2-way SLI. So he's not running SLI; that's not the issue here.
