  • extreme fps drops randomly. lasting 3-5 seconds each time.

    currently every few minutes i get extreme frame rate drops. my fps drops to 5-10fps for 5-10 seconds.
    i can however solve it instantly by alt tabbing out and back in of dota. my frame rate returns to normal immediately.

    specs of PC are
    i7 920
    6gb DDR
    win 7 x64
    running OS off a SSD

    i have console and d3dex9 (i think thats what it's called?) enabled.

    done a search and can't really find any other threads about this.
    any information about this?
