Goddamnitall, I thought I had a lead on GameMode being the issue, but the lag is back now. Fuck NVIDIA, but this is the best PC I have and it was a hand-me-down so I did not choose it. The games still run perfectly 1 out of 20 times, wtf…
I don’t believe so, I do not see the option either.
On further testing, the problem appears to be GameMode-related, disabling that makes Wine programs run without the lag. However, Also, now attempting to run Wine programs in fullscreen (any resolution) causes the whole system to severely lag and it takes a very long time to Alt-Tab out or Ctrl-Alt-Fkey into a tty session.
This is on a Western Digital Black NVMe SSD.

Edit: I forgot that I wanted to clarify that this is not a video playback issue, the lag happens in all Wine windows, even winecfg. I clicked back and forth repeatedly between config tabs and was also able to notice the lag there.
No difference running without Lutris.
