Windows client is currently fragile and crashes regularly. Crashes seem to build, so I can go one or two matches without a crash, then it'll crash once, and then crash every few minutes or so. My system is rock solid otherwise, and all drivers are patched and up-to-date.

I even uninstalled the direct client (and why were there like five of them?) and reinstalled through Steam to see if that version was more stable. It is not.

Please beef up your QA department and fix your windows client.
