I can literally play just about the whole game on maximum settings. 1680x1050 resolution (Native), antialiasing x16, render effects, and graphics on high. The only problem that I encounter in the entire game are flame vents or in detail the floors that ignite in flames. These bring my fps down to 5-10 depending on the amount in the room. Firestorm citadel is impossible to do without lowering my settings. The thing that really irks me here is that there is no other problem in the game that hurts performance other than this so I have to turn my graphics to low specifically for these flame vents.
It seems to me that something is just simply wrong here for this one thing in the game to be so much more graphically demanding than the rest of the game.

I think the problem here is that these vents create a huge amount of partical effects. In most online games I've played partical effects are a adjustable thing. The two ways to fix these vents in my opinion would be to add a partical effect toggle/adjustable setting or to simply lessen the effect significantly on fire vents.
