After downloading Steam and a few of my games, I have been testing on of the more graphic intensive games: Half-Life 2 Now everything runs perfectly, I was able to get it up to 80 fps, smooth gameplay, and it doesn't even feel like I am running it under Mac. Now the only snag is that I get an error every about 40 minutes stating that there is not enough memory. And HL2 crashes (not Steam, just the game). Now I have 4GB of memory, and HL2 only goes up to about 512MB. How can I give it permission to use up more memory? I want to set it to 1GB since that is much more than enough.
