I found my gpu performance monitoring software was showing a very little usage (or none) when using Premiere Pro 2017 in tasks where supposedly are accelerated by the graphics card such as warp stabilizer, exporting, etc.
I only was able to see certain peaks of activity but inmediatelly go down to 0% and searching the web and this forum I found other people are worried about this.
Is the GPU helping?
So I made some test.
Here is my build:
i7 3820 oc at 4,6ghz 4 cores 8 threads (this old boy keeps giving nice performance)
gtx 1050 ti
os and apps in SSD
project files, cache, renders and exports in a Samsung 960 evo m.2 disk via pcie adapter
I did some test with and without gpu acceleration in project settings with two 17 sec clips 1080 50p and 4k 25p
(gigabyte gpu monitoring software and GPU-z is what I use to see activity)
cpu only mercury playback engine gpu acceleration cuda
apply warp stabilizer
4k 5:21,63 5:19,53
1080 2:45,00 2:43,00
render preview warp stab. applied
4k 00:40,50 0
1080 00:48,10 0
render preview 40% slower with optical flow
4k 03:06,61 00:53,89
1080 04:59,00 01:32,55
export to h265
4k to 4k 02:25,10 00:29,10
1080 to 1080 01:18,53 00:19,53
Now that I see the results it is obvious that Gpu is helping (a lot) but it is not showing the expcted intense activity like the CPU does. So the GPU works in a different way or the monitoring software is not doing well.
I´m waiting for a 1080 ti. When it arrives I´ll do some comparisons with the 1050 ti. Although I´ll be expecting some differences I´m sure the 5x times more expensive card won´t give me 5x more performance.
