mouse lag is related to apic being enabled on motherboards giving the motherboard more irqs but giving up some of the control to windows

this is one thing i am worried about with ms wanting to head towards having windows and the bios more tightly intergrated

Some motherboards have bad implementations of apic and it can cause problems relating to a laggy mouse to stuttering sound. It will lag during intense use of other irqs like when your hd is being constantly accessed or cpu being heavily taxed. I noticed the problem with my pc when my computer was doing some video editing and my mouse started jerking along the screen..

Just remember that if you disable APIC you will need to reinstall windows or you have to manually change the computing driver under device manager/computer


Also some older ati hardware drivers had a problem with hardware enabled cursor that could be a problem i know my old 8500 with some older driver versions would have stuttering gfx. I still think APIC is the main problem tho.

yeah i thought this too but the problem is completely consistant, its slow all the time its not stuttering etc and inconsistant like you'd expect with an irq problem and I've already tried disabling APIC and reinstalling windows with very minimal hardware installed several times and it didn't help.

I have a P4P800 Deluxe and have exactly the problem you described. Simple solution: put your mouse on PS/2 and set it to 200hz. Mouselag gone.
Yes, I know you said that it wasn't usb or ps2 related. But it seemed to work for me.

I guess must be a different problem then with the P4P800 then as ps2 is just as bad here.

in fact ps2 at 200 is worser for me

afaik acid_mea and elaisen were having similar problems with the motherboards you just mentioned.

Does the nforce 2 mobo have probs with mouse lag?
gonna get one with winxp.
this abit kg7raid has lag.

It doesn't seem to be anything to do with the chipset, I know someone who has an nforce2 shuttle thing and its fine. But I'd avoid abit or asus mobos if you can just on the chance I'm not talking complete rubbish.

i have never noticed anything like that i must say....maybe because i play highsens (something around 30 right now)

you play sens 30 in q3 ??

i was on 57 long time ago...
and yeah, my drivers are set to 2/3 of the maximum speed, i even had to set them to 3/3 when i used mouseware (crappy tool), now with the razer driver i use 2/3, no accel and maximum speed in razer customizer

somthings wrong with you or your pc :)

You can play with this and do ok, I think most people wouldn't notice the lag except in direct comparison to another smoother setup. You'd probably never improve above 2nd league open cup standard or something though. The difference in aim it makes is about (q3 stats wise) -15% with hitscan weaps and worse with projectile weapons (can't just aim with strafe all the time).

exactly !

hmmn I can start a thread and say whose motherboard has lag etc (like I have). But a lot of people may say they don't lag not realising that they do or say they do when they really have some problem with XP or something. Maybe doing a poll of what mobos eurocup players (or equivalent standard) use would be more productive as you have to have ok mouse settings to play at anywhere near that level.

good idea

another oportunity to find a good mainboard, is to just simply ask what motherboards were used for eswc

mmn but then you only know that one motherboard is ok. What if its not what you want or is out of your price range etc? If we could get a larger picture of what hardware is and isn't ok then maybe we could identify the cause.

right, so where can we make such a poll ?

I've just been going round clan websites for half an hour checking out what hardware eurocup clans because its often listed on members pages. Anyway I'm not sure it is motherboards now. I have problems with my abit nf-7 despite everything I've tried with my pc but it does seem like theres players from top clans like mtw etc that use the same board.

If it isn't mobos tho I'm just stuck as to an answer as everything else in my pc is completely ordinary, pioneer dvd drive, gef4 ti, mx mouse etc that every other gamer has too.

im not sure if its mobo too

but its sounds most logic to me, maybe some setting in the bios...

nope, used same config on different systems too (and no, i didnt lower m_pitch / yaw)

Strangely I have no lag on my MSI K7N2-Delta-L (nForce2)...

But I do agree that Asus and Abit motherboards do tend to give more problems than other motherboards.

i complained a while back about my mouse feeling very unsmooth and i thought maybe it was something with my motherboard as well. the sensitivity feels very high when i move the mouse in small distances but when i spin around it's too low :\ maybe this has something to do with it. i have a Biostar M7VKB motherboard VIA KT133 chipset. and i'm using an mx300 on USB with windows XP standard drivers. anyone else having similar problems with this type of configuration?

do you use mouseware set to 800 DPI ? if yes you get neg. accel, search the forum for the modified razer driver (works perfekt)

yeah that definately sounds like you have the same problem as us.

I've got a absolute pos ASUS A7V8X (KT400 I think) and there are definately issues - but I couldn't say with any authority that they're not caused by XP.

gah XP..
I thought intellipoint fixed all the accel problems. Better just to install a better OS tho :)

you know what sucks most of all about these mouse lag/smoothness problems? we're all breaking our heads trying to figure out what is causing it. i wish there was someone to just tell us what the hell is wrong.

yes

in fact i break my head about this since a year or so now...

btw my old machine is a P3 600 and an ASUS P3V4X motherboard. I used an Intelliexplorer 3.0 on it with no lag problems.

Are you sure? Most people wouldn't ever notice it except in direct comparison to another machine without the lag.

dude I'm sure....I can 'feel' mouselag and I'd know if I had it on my machine and I can assure you that I didn't.

..that didn't really help. How do I know that you would know it? Its not like you drag the mouse and then half a second later the pointer moves. Unless someone either has outstanding precision aim or has played on another computer and noticed the difference, its unlikely they would recognise the problem (even if its been explained to them) and difficult to be absolutely certain they don't have it.

i would feel if i had it or not, 95 % sure of that

i even feel the lag in windows where other people dont feel anything

btw i installed the latest logitech driver for my mouse and surprisingly the mouse responds better in windows and in game, but then again i had a very bad lag, i think now its just normal (but still far from normal)

anyway im 100 % sure there is an abnormality, i used to doubt it since so few people noticed it :O

i used to have a P II 266 MHz without mouselag (and it showed, i could play Unreal Instagib really well after only 3 months of playing, and now, 3 years later or so i suck bigger then ever and i refuse to play it anymore since i have this pc)
so it cant be caused by a pc with low specs

it must be some piece of hardware that causes this or maybe when you have this bad piece of hardware you can fix it with something of software but i doubt this now a little, since ive heard many people say (with no mouselag) that they dont tweak anything, they just use default settings

i just want to say my motherboard is not listed between those mentioned in the thread, i have a MSI K7T266 Pro2 and i have mouselag

i searched the whole net for mouse lag related to this motherboard and i couldnt find a single thing, its almost as if this problem doesnt exist, allthough im absolutely sure it does

my problem used to be worse but since i installed the latest driver from logitech i can play at a reasonable level, but still with a too high sensitivity i have trouble turning 90 degrees :o (and i dont mean a high number of sensitivity, i mean it feels very high)

*edit* btw this has nothing to do with negative acceleration, i had negative acceleration when i installed an older driver for my mx300 and it wasnt even as annoying as this lag, because alteast that was controllable

I think I always had mouse lag on all my computers. The problem is, I don't necessarily feel it.

Some time ago (years I think) I checked out some Linux distribution and installed it parallel to Windows. That time NVidia just had released their first OpenGL driver for Linux. I installed Q3 for fun and then I noticed, that the mouse felt more "fresh" or something. (A week I later I won a Q3 1on1 tourney on some local 500 ppl lan, and I swear I only managed to win the final match because of Linux.)

You could try "Jollix" Linux: http://www.jollix.de/en/en_download.html

Jollix uses a bootable CD. You don't have to install anything. Just burn the ISO and boot from the CD.

Try downloading and running the Linux Q3 point release or stuff. They also have a Windows Emulator so you could try to start a Windows HL installation.

After that you should know if it's your hardware or your Windows installation, which is causing lag.

yeh i tried linux before but it seemed to require way too much effort. There didn't seem to be any decent server browsers or irc clients and I couldn't find out information on how to change things like display refresh rate and vsync and mouse settings and stuff and besides which you can't play many games except quake (though I do desperately want to play qw + q3 again) and I found having to continually reboot back into windows ever so tiresome.

yes but i personally would like to play normally under windows !

there are so many people that have their mouse working without this lag under windows with default settings, i want that too !

im too pc noob to start working with linux, and my parents and my sister use this pc too btw

maybe its a good tip for someone who wants to try it

and i dont play quake personally, only cs since thats a game for slow aiming and so the best for my mouse

im into UTinstagib though, ill start playing that again if my mouse works normally again (ever)

I just exchanged my abit NF-7 mobo with an ASUS A7N8X-X, I didn't have to change any drivers (as their both the same chipset) and all the bios settings are left on their defaults etc The mouse lag is gone. So I think it must of been the motherboard. Though from what deep0r said and my own messing around with linux it may be a mobo + windows issue, I don't honestly know.

so do you think the lag would be gona when i bought a motherboard that the cpl uses ?

im planning to do so

would be absolutely great if the lag was gone, ive been waiting over 2 years for it now ..

i just hope its the same lag (like the mouse has a shortage of energy all the time)

you have no mouselag under linux or windows with the A7N8X-X ?

it is lagging. I just tried qw for 5 mins before I left this morning after I put in the mobo and seemed better but then I haven't played in ages so.. But I've been messing around more tonight and tried q3 too and its still crap like before. Maybe a little better but its not 'fixed'. Think I'm just going to give up ever playing again its a waste of time and money etc.

youre the first person wich shares this kind of thought with me

its realy pissing me off that i already spend like 700 € or so without any success...

it realy doesent make any sense to play on fps games...

god damn....how could quakers all over the world play GREAT tournaments, organize BIG events and having a LOT of fun ? maybe because they didnt know this "bug" ? have you ever seen anyone who really cared about this befor you came up with it ?

now everybody jumps in "i got that too, thats why i'm n0 1337 pr0-g4m3r" and so on...

gaming was fine all the time, why should this little "thingie" (which i never really noticed) suddenly make us all stop playing.....

youre saying it like everyone has this bug, this is not true

ive seen mice that could turn 180 ° back AND forth in a matter of a second and this with very low sensitivity + no acceleration

this is just how i explain the difference to you, theres more to it

and personally i dont think i can be a pro gamer, i can just play a lot better than i do now, 100 % sure of this (and with this lag im at my top level now, after over 3 years of playing games)

dont answer the thread if you have nothing helpfully for us.

and nobody jumps around saying "thats why im no pro gamer" we just try to help each other thats all.

Its boring playing with mouse lag. I can't hit any nice shots or do any complex movement tricks. The only way I can compete in matches against semi-decent opposition is being ultra defensive, whoring armour and health and making sure I only fight people in flat areas so I can aim exclusively with strafe. Its boring as hell and no fun.

soooo damn true man, exactly the same for me, the only reason i still play is probably because i only like to compete.

and its not only annoying for yourself, its always more fun when both players can play offensive at highest possible level imo. Hardly ever a ":)" is worte by me or my opponent in my games...

At every level players are always asking whats the best mouse, mousemat, drivers, how to fix mouse acceleration, what config people use, whats their mouse settings, how to hold the mouse right, whats the best replacement mouse feet, it never stops. And this bug makes more difference than all of that put together so don't tell me nobody cares.

so true

i really dont get what can make you better by buying all the same things as a pro gamer, you are not the same person are you, and even he might want to have another setup

thats just plain stupid imo

we have a serious problem and we want to fix it
its possible that buying the same pc as a pro can fix the problem, so if you need a new pc, why not buy the same ?

This might be a stupid suggestion but...

Under the ABIT NF7 Bios there is a USB setting related to USB support which can either be set to BIOS or OS.

Have you tried changing this and did it have any impact?

/e[N]eq

tryed it

didn't have any impact

also tryed many more usb stuff wich did not help, thx anyway

check my journal for some fixes that worked for me =)

disable the cpu stop bit in the bios you should notice a marked improvement

Wow so this was the first thread ever posted on ESR?
