Low GPU Usage

[HOSKER]

My GPU is running at 43% utilization, is that normal?

It is an RTX 2080 Super, CPU is maxed out and running fine.

I've done no overclocking etc..

Divers are up to date.

Hi and welcome to the forum!

I strongly suspect that your GPU utilization is actually around 95 or 99%. The calculations are highly optimized and are geared to used hardware as efficiently as possible. Task Manager looks at specific measurements from the GPU, such as rendering load, but isn't technical enough to look at the actual load on the GPU from general purpose calculations. For that, I recommend a tool like GPU-Z, which can generate a graph of the true GPU load.

In Task manager you need to change one of the windows under GPU to CUDA by clicking on the down arrow. That will show the CUDA compute load, which will probably be 90% or higher.

I stand corrected, I didn't realize you could do that in Task Manager. faceplam Thanks Joe!

[HOSKER]

Perfect, thank you!

I use GPU-Z's sensor screen to measure GPU utilization, it gives wonderful details.

Just passing along things posted by someone else. For AMD cards it is one of the 'Compute n' options. Moderating I have to skim through a lot of posts, especially first posts by new members, some info even sticks

Adding to that info: Running an ASUS GTX 1060 personally, I don't have a CUDA option - but 'Compute 0' shows 95%+ load.

Which version of Windows? The Cuda option may be a recent addition.
