I could try different sources, but my experience so far was an almost unnoticable FPS change, even when changing presets.
We need someone with RTX 2060 / 2080 to verify

I'm seeing quite a bit of difference between presets when running against the same source. The "performance" preset, for example, is running much faster than "default" or "quality". It can also change based on whether I am using --vbr or --vbrhq.
For example, on a specific UHD source I'm using for testing with preset "performance" and "--vbr" I am getting 127.49 fps -- the same source with "quality" and "--vbrhq" it is doing 77.67 fps (with an otherwise identical command line).
I am also seeing fluctuations depending upon the size (on disc) of the source. An imported 10GB source M2TS encodes faster than a full 60GB untouched source.
The largest factor to speed I've seen (as you might expect) is whether I am using --avs as the input type as opposed to --avhw or --avsw.
