You can safely put a QCK+ in a dryer with a towel and put it on Knit Dry (Low Temp settings, the no temp air dry setting works obv)

I've been having this issue as well after the last 2 updates, still trying to narrow down what's causing it.

I can tell when my fps hits 180 or lower... Mouse response just isn't the same.

Can I see the tracert?

close out of background programs (especially Google Chrome if you like extra tabs/extensions)

if you're comparing your system to say mine I have high CPU OC
CPU: i5-4670k @ 4.4GHz (Haswells do better at single thread by about 5% than Ivy Bridge)
Motherboard: Gigabyte Z87-HD3
RAM: 16GB DDR3 Corsair Vengence @1600MHz
GPU: HIS 6850 1GB

Run in DX 8.1 or "-dxlevel 81"

Try out "No Hats Mod"

Achieve better FPS

-edit-

if that doesn't work let me know

Thanks for the heads up

honestly from what I've seen so far and from what it looks like classes do that this game is going to be extremely stalematey

Their's 1 Sniper, 2 or 3 engineer classes, 1 huntsman Sniper?, 1 soldier, 1 scoutish class, 2 melee heavies, 1 medic, and a gun spy...

I could be wrong though.

The performance impact isn't going to be as significant as some might think. Going from multithreading to single threaded does about 20% less framerate -maybe- but if you're using basically any modern i5 or i7 you should be well over 60fps.

1st line of the autoexec

"Unexplained crashes? Try changing mat_queue_mode to `-1'."

will probably help you out, and since you're only doing camera work and not playing the lower fps should be fine.

Could also try 0 or 1

not entirely sure if this will work for you but

tf_forced_holiday 0/1/2/3 - 0 = default; 1 = birthday; 2 = halloween; 3 = Christmas

try setting that to 0 before you launch you demo since it creates a listen server it might work...

With the way RAM reports it's speed to output programs it usually goes 1/2 of what they actually are because it's DUAL Data Rate. The OP probably has a poorly timed 1333MHz or 1600MHz 8GB stick of RAM. Upon looking at his reply it is a very poorly timed 1600MHz 8GB stick. BTW "Single Channel" typically means he only has 1 stick of ram.

OP get a Intel CPU + Motherboard i5s and i7s will get you the framerate you want.

Also

cl_threaded_bone_setup 1

that command should help you alot

could also use my entire CFG + the mods I listed here http://teamfortress.tv/thread/20172/my-fps-config but the above command will help you more than just about anything else

need new video card...

No clue, wish I did.
