Huge FR drop SC2 with MBP 09

[Avicenna]

i am running SC2 on my MBP 09. 2.8GHZ C2D, 4GB RAM, 9600M GT. I get huge frame rate drops at times for like 20 - 30 seconds. I can turn the settings to lowest, but then it looks like SC1…lol.

If any one tried it with their MBP, please share the settings on which it runs smooth, but doesn't look like SC1…. Thanks.

Downgrade to 10.6.3 or use Windows. Apple messed up in 10.6.4 with owners of NVIDIA GPUs so they get poorer framerates.

How do I downgrade? Thanks.
