100%cpu and 40%GPU is this normal?

I got a Ryzen 3900x 12/24threads and it runs all 24 threads at a steady 100% My GPU 2080ti runs around 38-45% with 2x with settings all default. Is the CPU bottle necking the GPU? I wonder if getting a Ryzen 5950x 16/32 would lead to more GPU usage.

You should check your CUDA usage, if it's close to 100% the CPU should not be affecting the speed. In the next updates I will make batch processing work again, so it may give some speed boost for you.

CUDA usage is different then GPU usage? I was using gpuz but don't see anything for cuda specifically. As rife uses gpu and cpu at same time getting a faster cpu would help anyway provided I can ever buy one as its always out of stock.

On Task manager, you need to select yout GPU and select Cuda.

Don't get a new CPU, you should have a performance boost once I get batch working again.

With 1.71 with everything default and batch of 2. I might try updating the video drivers later to see if that helps.
edit. it seems using batch of 4+ improves GPU utilization while 2 uses little.
edit 2. batch of 1 with a 10 second test 1080p 24>48fps video is about 30% faster then 2+.  Ive tried some 480 and 720 and about similar percentage. So for now 1 is fastest for me.

I am wondering if its possible to add a stop button. Right now the only way to stop is to close the program completely. This would be nice when trying different settings to see which works the best. Thanks.

Even if I create the pause button, changing the setting during that time would be complicated to implement, but the next update will have a "Cut" tool that will help test multiple configurations.

It does seen your bottleneck is the CPU, but you seen to have a pretty beefy computer, so it should not create a bottleneck at 1080. I might need to take a better look at that.
