I was able to successfully play matches online (with one random crash in
approx. 4 matches) with reasonable fps, when all game settings are set to
lowest possible. Now when some spells are used or near some buildings (like
hellborne towers), game becomes unplayable and there is even some corruption.
Also game console output which was few lines long before is now much longer
(3,6MB from approx. 1 minute gameplay when using offending spell).

How to reproduce:
1. start HoN
2. Start Tutorial
3. Cast Phoenix wave at some enemy creeps or go near some hellborne tower.
