Running the performance test tool i've found out my i7-8700 is able to render at the following rates:
With Mercury Software Acceleration (general settings + project)
Using Legacy title: 20fps. Pixel format VUya.
Without any title, 77fps. Pixel format nv12.
With Essential graphics titles: 21fps. Pixel format VUya.
With a 2160p transparent PNG with the text on it: 25fps. Pixel format VUya.
With a small (text size crop) transparent PNG with the text on it: 34fps. Pixel format VUya.
With Mercury Hardware Acceleration (general settings + project)
GTX 1660 goes 100% usage here in task manager, however it is not video encode or decode what is causing the load.
Using Legacy title: 11fps. Pixel format VUya.
Without any title, 12 fps. Pixel format nv12.
It looks we hit a hard limit here for some reason. I didn't try further with this global + project hw enabled.
Disabling the hw accel option in the project but leaving it enabled in the global preferences:
Using Legacy title: 25 fps. Pixel format VUya.
Without any title, 74 fps. Pixel format nv12.
Exporting 4K video resizing to 1080p with titles: 25fps
Exporting 4K video resizing to 1080p with titles: 33fps
Exporting 1080p video: 171fps, pixel format nv12
Basically I can see that the cpu is somehow limiting me. However, I also see a previous message talking about the pixel format. Is that something I can change somewhere? I went to sequence settings but I wasn't able to find pixel format anywhere.
