Post all your useful hints, tips and tricks here.

That's anything that helps the game go faster, smoother, reduce glitches, reveal hidden easter eggs etc. You get the picture.

Cheats are fine too, as long as they are of the variety to help out in single player, such as enabling god mode, weapon unlocks etc not to nail online players unfairly.

I find that atm if i suddenly get really bad framerates (usually near the end of a level, or in the park area in the second stage) alt-tabbing out and back into the game helps clear it up nicely.

Also i found it a bit hard to find the option to setup a lobby (so i could use my l4d2 dedi server) - go to campaign > friends only game> create lobby then change the setting from friends only to public and you can then start a public lobby. I really couldn't see it in the normal multiplayer campaign choices so i think this is the only way at the moment.
