Turelus

I have been looking all over the interwebs for answers to this but found none so I thought I would post here with a request for aid.

I installed PS:T with latest patch, tweakpack, fixpack, widescreen, gui-fix.
Now starting up the game I notice I had the issues from the nvidia card/drivers so promptly went and installed the nvidia fix which sorted the fog of war and transparency issues, however it now seems to not sprite mirror correctly this was quickly solved by enabling the option in the graphics settings and the game was running fine and dandy... until I become a mage! now the game is playable fine until I cast a spell at which the time screen flickers like mad and I get horrendous lag making combat as a wizard almost impossible.

I was wondering if this is an issue that has been solved in the past and I could recieve and help & advice or if I just need to suck it up like a man and play with lag when I cast spells.

(sorry if this has been solved in the past I have run several google searches and looked through your boards but found nothing)
