Intel Video Cards with Day of Defeat: Source, Portal, Team Fortress 2, and HL2: Episode 2
Question

Whenever I try to play Day of Defeat: Source, Portal, Episode Two or Team Fortress 2 I experience a crash or a hard freeze. Half-Life 2 seems to work fine though. I am using an Intel based video card. What can I do?
Answer
Intel Compatibility Issue

If you are playing the new Orange Box games or Day of Defeat: Source on a laptop or a system with an integrated Intel video card such as the 945 GM, chances are your video card has a compatibility issue with the following games: Portal, Team Fortress 2 and Half-Life 2: Episode Two. Intel is currently working on updated drivers that will resolve the issue. Unfortunately, there is no ETA as to when those drivers will be made available.

In the meantime, you can try running the game by using the following launch option:

+mat_bumpmap 0 +mat_picmip 2

If you're not sure how to set game launch options, please see this guide.

If that doesn't seem to help, you can try using the following console command:

mat_max_worldmesh_vertices 1024

If you're not sure how to use console commands, please see this guide.

If that command allows the game to run without crashing, then please add it to your game config files. Your config file is located in the SteamApps folder, under your Steam account name and the folder for the game you would like to play. For example:

C:\Program Files\Steam\steamapps\< Account Name >\team fortress 2\tf\cfg
