...man i
hate these snakebunches, i can`t tell you!!!!!!!
this disgusting pack!!!! even more, than that buzzinghardtohit killerbees!!!
but now to that prob of yours:
sounds to me, like you have the game running on to high resolution.
the final demonkickassbattle slowed my system down also alot, cause it`s the most action in it.
that demon summons monsters like hell in addition to his spells, i think it´s just little bit to much there. i had summoned also several allies too.
what system are you running the game on?
i had my taskmanager runnig on my second panel, and saw that the "Auslagerungsdatei" (don`t know the english word for it - direct translation would be OUTSOURCED FILE ?) on the systemtab was growing very large and the cpu usage was permanent 100% there. then all got very bumpy.
perhaps decreasing your game resolution might help.
it did to me.
