How to deal with input lag?

dmxdex2020 · 24 Jun 2009 at 12:52

I normally play with vsync off and accept tearing but my card is a 4870x2 and is more than capable of vsync on. 1 problem lag lag lag movement feels delayed and horrible. i have heard it is input lag. i play cod 4 and would like to know if their is a way of sorting this out?

turning vsync off.

That sucks so i have to put up with tearing.

SLIPdiggers · 24 Jun 2009 at 13:31

That DOES suck.. anyone know the cause of this, cause i havent seen one on here.

Hope my new 4890 doesnt suffer anything like this.

Get a higher DPI mouse, crank it up, turn off all mouse acceleration.
Did it for me, its still there just barely noticable if at all.

Triple buffering is also notorious for causing this.
a lot of the times its also the actual game, some games just lag by nature.

How do you turn off mouse acceleration?

unknownsock · 24 Jun 2009 at 14:03

Theres options in some games, also in windows control panel > mouse.

Although if youve lived with mouse acceleration for a long time it will feel slow etc.
It's possible disabling it might make things worse if your mouse isnt up to job.

I tried cod 4 without tripple buffering didnt make a difference. i have a razer mouse which is 1800 dpi.

If i were you'd just mess around with all your settings in your razor drivers and widows mouse settings.
Infact do you use windows mouse drivers or razers? Could be worth trying the other out.

is your panel a newer TN type panel, if so that may be the source of the lag as new TN panel have a thing called overdrive, makes the pixels change faster so the manufactorers can claim 2ms times but it adds input lag

Except your screen is renowned for it's superb and almost non existant input lag................

My monitor is crt which is like 14 years old.

I always play with V-Sync on and can't say I've noticed input lag - perhaps you just get used to it after a while?

It doesn't really make any sense to me to buy a £300 card for nice IQ and then ruin it with horrible tearing.

I never actually blamed my monitor i was just saying i had that same specc, TN + 2ms

Although it would be nice to read up about this.

I notice tearing maybe once a week. Are you actually looking for it for it to bother you this much?

I never notice tearing except on areas with lots of parallel lines aslong as I keep the framerate high enough... which is one of the reasons I have 260GTX SLI...

VSync always induces horrid input lag and theres nothing you can do about it - some people notice it more than others.

So in summary - get pumping out 100+fps even if your display is only running 60Hz - and you should rarely notice tearing again and the game will feel much more responsive.

You're all talking at cross-purposes here. Input lag and the apparent lag caused by enabling v-sync are two entirely different things.

The former is down the screen and you can't do much about it if yours is affected (overdrive disabling notwithstanding). V-sync lag can be helped a bit by triple buffering in some games or by disabling v-sync altogether. Personally I use triple buffering in things like racing games were split-second reactions aren't required but put up with a bit of tearing in things like COD4 where they are.

Input lag is input lag, whether caused by panel electronics or frame time delay or anything else... its anything that causes a noticeable delay between the moment you move the mouse or press a key and seeing the response to that action on the screen.
