Just gave the beta a spin on my Linux workstation and it works like a charm so far (fingers crossed). I am super impressed by the subd to nurbs option. Fast and results are really good.
On a linux side of things I've accidentally forgot to disable dxvk in the wine prefix... and to my surprise it didn't cause any issues so far. Will check out the built in hud to check whether dxvk is being used.

So in the next couple of days I'll be setting keys / macros then will try opening some heavier files from Rhino. If all goes well I'll finally have a proper nurbs sketching on my regular PC :) .

edit: one glitch I've found so far - sometimes when I hide browser tab MoI seem to be stuck with the selection on one of the objects in the scene, on the active layer. Thus I can't select / move etc other objects. When I open browser tab I can select etc again. Hide browser - can't.
