I have always, since going to a GB of memory years ago, ran without a pagefile. I've never had a problem, because I don't use Photoshop. However, last night (system in my sig) I got an "Out of Virtual memory" error after about 5 autosaves in Half Life 2. I've never had a problem, even with Doom3 and BF1942. So, I created a static 500 MB pagefile, and the game runs great now. I notice apps like Outlook and Word don't open as snappy, but it's hardly a difference worth complaining about. Anyone else notice this?
