Radeon HD6490M problem running SC2 on the lowest settings.

post #1 of 2
Thread Starter 
Hey, first poster. This is a problem that i feel has been building up for a while, but only the last couple days starcraft 2 has become nearly unplayable! I'm running on a 15" macbook pro 2011 bootcamped into windows 7 64 bit. Here are the specs:

Intel core i7 2.0 Ghz (Sandy Bridge)
4 gigs of ram
500 GB Toshiba harddrive 5400 rpm (i think)
Radeon hd 6490m 256mb GDDR5

It's strange, i used to have no video problems whatsoever, the game would naturally run perfect at the beginning, as there are only 6 workers and your main building on the screen, but it would always stay around 60 fps no matter how many units there are in the match. Now my fps drops down to 20 when there are a lot of units, in big battles, it is lower and i have no control over what is happening.

I've tried installing new drivers, i always make sure to completely wipe the remainder of my old drivers before i install new ones (uninstalling everything from add/remove programs and using driver sweeper) and i'm currently runniing 13.4 catalyst mobility drivers for windows 7 64 bit.

I've noticed something strange too, i've been running tests using gpu-z and while i'm in 1v1 games the GPU load reads 0% the entire time, i know this isn't a problem with it reading my card because it reads 100% when i'm running a video stress test. It basically stays at 0% in game and occasionally spikes to 20% for a brief moment before going back down to 0%. Meanwhile when i'm in the games menus it will be at a solid 65%. It's really strange. I'd appreciate any help, TY.
