I am not sure if this is due to my system or if you are still optimizing graphics and game speed, so I am just going to say something. If it's being worked on or if my system is too slow just ignore me :)
On default graphics I would say that overall gamespeed while scrolling, zooming etc is average on my system and well playable in general. However the mouse cursor always feels kind of sluggish. I tried reducing graphics from default (while aware that this is not really supported yet) and the only thing that got the mouse to move even close to normal speed was switching the shadows to off. Since this helped a little the problem may be due to my hardware.
However while I definetly would say that frames and gamespeed are at a very playable level on default settings, the sluggish mousecursor is really annoying especially in engagements with multiple units since it is always lagging behind my movements and therefore hard to place. Is there any way to "disconnect" the cursor from the "graphics- or gamespeed" or something so that it behaves normally like on the desktop?
