SC:Forged Alliance Weird Slowdown

I'm about done trying to figure this out, but I have been having serious issues with this game. I love it to death but when it does this I am at the end of my rope. When playing SP Campaign, it runs excellently with everything on it's highest settings. When I play it MP OR in SP Skirmish it runs fine for about 5 minutes and then does a massive slowdown. Now, it isn't the frame rate. The game itself sets the gamespeed to -5 at the highest, and fluctuates between -5 to -7. I thought it might be the settings, so I turned everything to their lowest settings and it still did it. I thought it might be the internet, but that wouldn't explain the issue appearing in skirmish games also. This should not be an issue as I'm running off a Mac Pro Dual Core 2 Duo's 2GB and an X1800. ANY help would be pretty awesome. Thanks.

i say leave it about 24 hours before posting back - have you tried minimising the game when it slows? slightly odd suggestion but it might clear the ram or something....

supcom pretty much benefits from quad cores, might have too much stress on your CPU? i also wouldent recommend running high end games on a laptop with highest setting...especially in multiplayer when in about 5 minutes people have a bajillion units on the field, thats alot of stress on your computer

Oh ffs didn't even look at the dates myself.

*slaps self with trout*

Im running Windows 7 Ultimate 64bit with a Core i7 3.07gHz, 6 gigs of ram, and an 896mb graphics card. Its a desktop. I get the same slowdown, and I KNOW it isnt a lack of ram or processing power. 64bit operating systems can use more than 3gigs of ram effectively, thats only the effective limit of 32bit OS's. I know the topic is old, but Im hoping someone might know at this point how to fix it.
