Sadly i can not check that theory cause i don't own The Witcher 3.

I usually use wine-staging and the dx11 perf never was really good but i
haven't seen such a slideshow in wine-staging in the games i tried.

For Wine staging the fps have been bad with the following showing up in
different games (Crysis2, crysis 3, prey 2017):

CPU load:High to very high (utilizing 3-4 of my 4 cores)
GPU load: Low (mostly 30-40%)

So either wine is not feeding the driver fast enough or the driver is not able
to feed the gpu fast enough.There is a huge bottleneck somewhere. If a look at
the fps of the games they all would be really playable if the gpu would be able
to run at 100% load like it is on Windows.

In that specific case with wine-dev and crysis 2, the gpu is loaded ~ 50% but
the games is super slow.
