Patch 1.1 Is Coming

The first feature and balance patch release for StarCraft II: Wings of Liberty will be available next Tuesday, September 21. The maintenance period will begin at 5:00 a.m. and last until approximately 11:00 a.m. PDT. You can read all about our plans for patch 1.1 in the Situation Report.

I'm running 2.67GHZ quad-core core i5, 4GB ram and an ATI Radeon HD 4850. Been able to run any other game I've wanted at full setting. With everything loading in decent time. But his is just over the top.
you'd think they'd test the patch at least once before releasing it.
can someone help?
