How to decrease lag

[Uwillparish]

Hey guys,

 

Not sure whats causing this, so i'm putting it here, feel free to move it if its in the wrong place, But i'm having a bit of a problem, I play tf2 almost religiously, and lately I've noticed lag from when i click to when something happens, And i wanted to know if theres a way to decrease this, i dont know ifs its input lag or what it is, But here are the important specs

 

Monitor: Asus VE278H

Mouse: Razer death adder 

Motherboard: Gigabyte z87x-ud4h

 

The mouse is pluged into a USB 3 port on the back of my mobo, and my monitor is running from my gtx 780 through a DVI-HDMI to the first hdmi port on my monitor, if thats important.

why is the mouse on a USB 3 port?

[Aniallation]

- Does the issue happen in other games or on the desktop?

- Does the issue happen when mouse is plugged into a USB 2 port?

i dont notice on the desktop, and i dont play any other FPS's until GTA 5 comes out, and my pre-order is fulfilled

forgot to add, theres no usb 2 ports, #firstworldproblems

That's really weird that you don't have any USB 2.0 ports. Every motherboard I have ever seen has 2.0 ports simply for compatibility. Even X99 motherboards have mostly 2.0 ports. Are you on a gaming laptop?

 

One reason for the lag may be that you have a framerate lock on that particular game, and that's what's causing the lag. I got it a lot in Bioshock Infinite until I turned it off.

i use vsync, because it is how my sensitivity is setup, also, see for yourself

Vsync is the problem. See if you can't turn it off. Vsync is known to cause lag, screen tearing and artifacting, which is why Nvidia and AMD have been working on Adaptive Vsync.

well, let me show a video of this, http://files.vanillahills.net/Stream.mp4

are you playing on servers with low ping?

 

are you still using  tf2s awful default net settings? if yes put this in your autoexec

 

cl_cmdrate 66
cl_interp 0
cl_interp_ratio 2
cl_lagcompensation 1
cl_pred_optimize 2
cl_smooth 0
cl_smoothtime 0.01
cl_updaterate 66
rate 100000

Oh you're using v-sync

 

Yeah dont do that, also it has no affect on sensitivity unless for w/e reason you're using it because mouse acceleration in tf2 is based on fps

 

If you want to use mouse accel use the quake live mouse accel driver

i dont think im using mouse acceleration, please refer to the video a few posts above

 

EDIT: SOB i am, it says its recommended for raw input though, should i ignore that?

I cant view the video atm

but i'd recommend turning mouse accel off and turning raw imput on

i've had it on

Vsync doesn't cause screen tearing, it prevents it.  It's it sole purpose...  Adaptive vsync doesn't do anything but turn on vsync when your framerate exceeds your refresh rate and turn it off when it dips below it.  It does this because for vsync to work with frames rates below your refresh rate it has to limit your frame rate to halve your refresh rate which is what introduces lag...  I can only assume you were thinking of variable refresh rates.

so should i leave it on

It causes an amount input lag.  The only reason to turn it on is A) There is screen tearing and B) How sensitive to screen tearing you are.  Very few games have I had tearing to the point where I needed to turn it on.  While others fixate on even minimal tearing.  I'm also not sensitive to vsync's input lag.  The only reason to turn it on is if tearing annoys you.
