I'm having some weird issues with TF2.
1st. I can only select the minimum resolution.
2nd. It crashed my system with the default settings.
3rd. Sometimes it doesn't read the keyboard, but the mouse is locked on the app.
4th. Incredibly bad fps. less that 20. no kidding.
I have to give this a bronze.
My system is a intel duo 2.3mhz iirc with an ATI 4850 running Ubuntu 64 bit.
The crash took down the graphics, so it's some problems with that but, when I changed the settings it seemed to me that disabling the microphone was what allowed the game to function.
In order to get the game not to crash my system I lowered all the advanced graphics options to their minimum.
Here is the funny thing: while playing this game on win764bit I experienced my first blue screen of death on win7... again I think it was related to the graphics card.
