Hey, i already posted about this before but I'd like to ask Droidz if this is fixable because i don't think its normal that i can run around 25-30 vanilla wows+bots and I can't even run 10 TBCs (even with DXtory on), it often happens some wrobot instances are as high as 20-30% of my CPU which is WAY too much to use from i7 4790k. Any thoughts/help with this?

Do /console maxfps 10 ingame for the time being.
But yes, I think this should be investigated - although you need to make sure this happens even with an XML fightclass and NO plugins.

fps is limited to 20 with dxtory, and ill try things you suggested, thanks
