Important if you're gonna play Alien Swarm!

I forgot to post this rather important note about alien swarm.

On some systems alien swarm has been known to raise the temperature to abnormally high levels.

It's been reported by several users on steam that their computer either burned out or did fail-safe shutdowns because of Alien Swarm. The game probably isn't optimized at all right now.

HOWEVER.

There are measures to prevent this, if you're planning to play alien swarm you should take the following precautions:

• In the video options, set multicore rending off, one of the issues is processor temperature rising, multicore rendering heavily contributes for that and doesn't even help that much with performance.
• Still in video options, set VSYNC on double buffering, anything else will heat up your GPU greatly, which is the other issue people report with the game.

After these 2 steps you should b safe as many steam forum users reported, however, if u want to take it an extra step, get a system monitor app that monitors the temperature, play windowed, and keep an eye on the temperature of the CPU and GPU as you play. Play some other game you own first as reference (like TF2 or portal) so you know how high the temperature should go normally.
