So I have an RTX 2080 card and even if I enable GPU acceleration it still ONLY uses my CPU 

which is very annoying because my cpu can often times get very hot and is slower then my GPU

 

if I run GPU sniffer I don't get much

Vendor: NVIDIA Corporation
Renderer: GeForce RTX 2080/PCIe/SSE2
OpenGL Version: 2.1.2 NVIDIA 436.15 26.21.14.3615
GLSL Version: 1.20 NVIDIA via Cg compiler
Monitors: 1
Monitor 0 properties -
   Size: (0, 0, 1920, 1080)
   Max texture size: 32768
   Supports non-power of two: 1
   Shaders 444: 1
   Shaders 422: 1
   Shaders 420: 1


--- GPU Computation Info ---
Found 1 devices supporting GPU computation.
CUDA Device 0 -
   Name: GeForce RTX 2080
   Vendor: NVIDIA
   Capability: 7.5

Hi there,

 

You may refer to this link to know more about the GPU utilization in Premiere Pro.

Everything you need to know about GPU in Premiere Pro 

 

Thanks,

Ann,

I'll try and update this doc, fix broken links, and place it into a forum post for future reference. 

 

Thanks!

What is the CPU and how much RAM do you have?

 

I would note, the GPU is only an assistant to the CPU/RAM subsytem in Premiere. It only does things from the GPU Accelerated Effects and only then, when the CPU gets to the things it sends to the GPU. Which are things like Warp, Lumetri and some other color things, and major frame re-sizing work.

 

For general renders (for internal use) and exports, if none of the GPU effects are enclosed or they are used sporadically, then the GPU isn't used that much. And if you have comparatively an under-powered CPU compared to your GPU, that GPU is going to sit around quite a bit waiting for the CPU to get something for it to do.

 

Unfortunately, a lot of computers are set up on motherboards with throttle-necks between lane assignments on the motherboard and especially affecting the cards used on those mobos, and poor choices of internal data routes besides for the CPU and the drive connections on the mobo.

That's true, Neil. If you're exporting straight H.264 footage that is the same size, frame rate, and color space as your originals, with no GPU accelerated effects added, the GPU will do next to zero work for you. Nada! Encoding video is a solidly CPU process.

Sorry if this was news to you, sketch_boys, or do we have this wrong? Do you have any effects in the Timeline? Are you scaling on output? 

 

You'll see the GPU spring into action once you scale the footage up or down, add a Lumetri color effect or Warp Stabilizer, etc. Try it. What happens? Let us know, my friend.

 

Thanks,
Kevin

SB,

Sorry my friend. Check Help > System Compatibility Report. Then, post a screenshot. Let's see if your drivers are being detected.

 

Thanks,
