A Smissmas Miracle! (major TF2 performance increase)

[Dragonsbrethren]

After today's Steam client and TF2 updates, I'm getting a much higher framerate than I previously had. In fact, it's significantly higher than I get in Windows now! I never got around to doing any real benchmarking, but I'd say I was typically getting around 30-60 fps previously, but now the lowest I've seen it go is into the 50s during heavy action and well over 100 as the high number.

Things aren't perfect, the game still has occasional stutters and load/server connect times are still ridiculously long, but it's a major improvement over how the game had been running yesterday.
