Issue Report: TF2 performance poor until settings change
I've noticed that every time I load a fresh game of TF2, it runs extremely chopping. It claims to be getting 60FPS but is very stuttery and hard to play. Changing any setting in the video options fixes it as soon as it's done reloading, and it's smooth as butter and runs perfectly.

Thanks for the info.

Along these lines, I've noticed that steam will be sitting at 100%-105% cpu usage why TF2 is running. Killing steam after TF2 launches substantially improves performance.

The same here…!

And here; unfortunately, TF2 segfaults after a while if steam is killed, and so remains fairly unplayable for me :( *subscribed to thread*

Right, I've actually been too afarid to try killing steam while in a server against human players fearing it might lead to my ejection or something, but against bots its makes a massive improvment.

i lowered my video settings and it works much better

I'm having the same problem. I'm on Arch Linux (64-bit), and TF2 is quite jittery due to Steam maxing out both of my cores while I'm playing the game.

Is this an unusual problem? Do other people have smooth-as-butter TF2 experiences, with Steam using no CPU?

I noticed that disabling the in-game Steam console helped a tiny bit, but not enough.

Nothing seems to have changed for me, Steam is still hogging the CPU when playing TF2.

Almost same problem here :
TF2 Performance are really random ( sometime , it run like a charm and sometimes, the perfs are just fluctuating so fast ( 10fps -> 60 fps -> 10 fps ) )disabling the antialiasing makes me 60 fps all the time .
I also had 1 black screen on the 3d rander ( the 2d HUD was working smoothly )
Steam CPU usage is 100% when running tf2 .

I get fps fluctuations between 20 and 100 regularly when playing tf2. While it doesn't affect my ability to play the game, the problem gets worse when there are more moving objects on the screen.

Not sure this will help others, but using 'nvidia-settings --load-config-only' in my xinitrc fixed my issues. Apparently even if you have vsync turned off in the settings, those setting aren't loaded by the driver except when nvidia-settings loads, so you have to manually force it to load or vsync will get forced on giving poor performance.

vsync shouldn't be causing a high cpu load though, it should reduce it, no?
Vash 2012년 12월 17일 오후 1시 21분 
My issue isn't CPU load. It might be higher than Windows but not enough to cause issues. I do have six cores with Hyperthreading though. My issue was latency added by vsync, which I thought I had disabled.

ah, my bad
