increased CPU load in things that never had

[phatboy]

Morning all

I have been playing some old game this morning, which up until now have always ran fine, but now i seem to be getting lag and stuttering with xfire both on and off, and a CPU load of 95-100% constant. Pro Street used to run fine at circa 60+ FPS, but now its laggy as sin for no reason

Any clues as to why this can start to happen? Sup Com was the same a minute ago too.

Take one of the 4770s out and see if it goes back to normal. Does crossfire need different drivers maybe?

with the second card, it makes no odds if xfire is disabled, it just sits there from what i know.

Was one card in 16x pcie and now the two are in 8x? (not that this should make a difference) Process of illimination, take out one card, test. move card to slot it was in before, test. Change drivers, test...

This does sound like a driver issue to me. I had something very similar with my IGP. It turned out that the mirror driver installed by logmein.com software was causing issues. I disabled it and problem was gone.

If you cant work out what it is it may be worth trying rolling back to a system restore point...?
