It's worth noting that this game can be played natively with Arx Libertatis, which has improvements. The free copy will require running the Bethesda launcher, which isn't for Linux though. The instructions can be seen here, and is available until May 31 at 10am EST.

GOG has DRM-free version too just for the reference, and it's pretty cheap now.

Libertaris is a fine port indeed as I'm finding out..

but maybe someone can shed the light on:

Is it possible to AIM with MOUSE LOOK when about to release a spell?
in other words, I've correctly "drawn", say, a Magic Missile and I'm still holding the MAGIC key - but I can only aim with turn left/right up/down keys or screen edge turning???
given the disadvantage of having to draw the runes in the heat of the battle, it makes the usage of non-precast aim spells almost prohibitively cumbersome

^^^^^^^^^^
No it's not...
