[The_Joker_Killing_Joke]

New OS installed (removed vista and got xp back) and now I can't TF2 for shit.

Two issues:
One, my characters slide an few inches instead of "stopping on a dime" whenever I move/strafe etc. Which throws my entire precision game out the window.

Second, I get horrible video stutter/horizontal flashing lines whenever I die and it zooms in on who killed me. Even frapsed to show: http://www.megaupload.com/?d=R676AZJH

If it helps, I've updated all my drivers on my mouse, my keyboard, my monitor and my video card.
G5 Mouse
G15 gaming Keyboard
Syncmaster 226bw Monitor
GTX 295 Video Card.

Until I resolve this issue, I'm Shit outta luck, and with the sniper update just a few days away too. >_<

First issue shouldn't even happen. This sort of thing is generated by the game/server itself.

So I'm sliding around but noonelse is?

Also, could it be a keyboard/mouse setting I don't know about?

Found your first problem.

Open the console, type cl_predict. Make sure it's 1. Not 1? Type cl_predict 1.

Most peoples natural reaction to having game problems is to get new video drivers.

You can always try going back to an older version of your video drives (the ones on the CD).

My video card can't do anything with the "updated" drivers. When I put back on the ones that came with the CD everything runs smooth.
