Left4Dead 2 wont run on Core i5 MBP?

[Maximus434]

Can anyone help here?

Everytime I run left4dead 2 on my new Core i5 2.4Ghz MBP (bootcamp with Win7 64bit) It gets to the main screen, I click quick match and it begins to load, however once it's finished loading the game crashes to desktop. This has been happening since Valve updated it with the new "mutations" game.

Has anyone else experienced this? I'm extremely frustrated since I love playing this game and valve don't support bootcamp on mac computers.

Anyone?!

Works on my mid 09 MBP, so I doubt its your hardware.

I figured it out. It was crashing after the loading screen with the following error.

Turns out it's a shader problem. I changed the shader detail from Very high to medium and now it runs without problem.

Makes no sense though because it ran at very high before this latest update!!
