Demigod works perfect untill..

Gmae works on every arena and everything aswell,my pc stands for all req and only couple minutes or as im advancing in game it begins to work slowly and slowly,I start new match on level 1 and for the 2 minutes game was running perfect,but after I died or something happned ingame it just came to be slow and slow,so as on.

I have really nice pc,I tried to increase preformance and to clean but still,every other games with higher req works better and this ones just getting slower by the time im playing.

Thanks in advance to everyone.
