big lag spikes

Drkalinium · 2 Mar 2012 at 03:08

While playing certain games I keep getting random lag spikes I've checked my grfx temps and my cpu temps and im fairly sure its not a heat issue. I am also confident that it is not a driver issue as I've updated my gfx drivers regularly causing nothing to change. the two games I notice this problem in are crysis 2 and bf3 im not sure but i think it might happen in others just havent got round to checking yet when im playing in either game i get above 60 fps on max but then i experience huge fps crashes down to 10 fps or lower sometimes 1 or 0 then it recovers BF3 is slightly worse than crysis and is unplayable were the crysis 2 lags are more of a minor nuisance.

specs
CPU i7 230 oc'd
GPU 2x 5870s
RAM 6GB RAM

Could be a crossfire problem, a lot of crossfire users complain about micro-stutter in certain games.

edit/ have you tried running with crossfire disabled?

ah no I haven't ill give it a go but i would have hoped ATI would have fixed the issue by now if it is crossfire as its been going on for a while
