BF2 Engine: Mouse moves in a grid

Thats something that bugged me since years when I try to shoot someone at long range in a BF2 Engine game.
I can't aim at a single pixel.
The mouse just jumps in a grid of a few pixel regardless of the movement speed.
I tested it with MX518 and the MX500.

hmm what is your DPI and sensitivity at?

I'm probably wrong here, but isn't that just a limitation of the mouse itself, and why a higher resolution mouse is preferred?
Have you tried fiddling with the sensitivity?

DPI and sensitivity doesn't change anything except the slower or faster movement. The grid stays.

MX518 is a pretty sensitive mouse. I guess it doesn't happen in other games? Does it happen in BF2 vanilla?
Also your mouse should always be on the highest DPI setting and then you tone down the sensitivity to the right speed.

DPI is sensitivity but it also is the resolution which ur mouse is able to scan? i remember reading something about how if u have a high DPI mouse, u should set the DPI settings to the highest setting and then lower the windows mouse sensitivty setting.
tho it seems like ur BF2 is doing weird things.
hm, you can try going to control panel > mouse settings > and on one of the tables like Pointer options, turn off Enhance Pointer Precision. i find it makes it easier to aim and do stuff with that off.

i am having the same issues for years/forever
i never found a fix - and other games are fine
its seems that it is more appearent the higher your resoluiton is (i am at 1920x1200 and sniping is horrible)
only thing that helps a bit is to lower the sensitivty on the fly and wiggle around - the grid doesn't seem to be consistent since its sometimes possible to hit to a certain pixel on the second try if you approach from another direction/angle
fyi: i got it with razer diamondback and razer diamondback 3G on a special mouse surface on high and low sensitivity (razer) i never touced win sens except for turning off acceleration. happens in vBF2 and other BF2 mods alike

I've noticed the same thing in PR and never with any other games. Although I've got a pos generic wireless mouse.

Ive got a Logitech G500 and when I knock the sensitivity right down then it literally feels like its hanging until you move it enough to jump a grid...

Hi Ive been lurking on these forums for a while but Ive just signed up because ive got the solution to your problem
I use an mx518 and I had this problem for ages and it used to really bug me. Anyway Im guessing youve got your mouse sensitivity cranked up high in your game options. Go into controls and lower the mouse sensitivty to maybe 1 or 2. Then you can increase it on the fly with the mouse but more importantly you can then move the crosshair 1 pixel at a time.
Please if this works then come back to the forums and let me know its sorted it for you. It worked for me. Goodluck

Yeah the mouse movement jumps by preset amount of pixels which results in small areas that you can't actually aim at without moving or relying on deviation to land a hit.

OK I just checked. My in game mouse sensitivity in the controls is set to 1. I used to have the very same problem until I lowered it. Im using a logitech mx518 and i increase sensitivity on the mouse as and when i need to.
Has anyone tried my fix? Worked for me!

DPI is not the problem here, even if you have high DPI or low DPI it doesn't mean it jumps like that it should cover all pixels just fine. Best to try have different settings in-game or in windows settings. The software side sensitivity is basically "how much mouse moves for each dot", so if its set to high it looks like its skipping.

I know DPI isnt the problem. Forget your DPI settings. Im going to have one more attemp at explaining the solution for anyone with this problem.
Go into the "controls" menu in the "game options" and on the first screen change your sensitivity to 1. Thats it!!
I lived with this really annoying problem for a long time (teamates screaming at me "shoot him" and I just couldnt do it past 200 meters) until I accidently come across this solution. If I turn the sensitivity back up in the games "controls" menu then the problem comes back. If I turn it back down to 1 or lower the problem goes away. There is no reason why anyone should have this problem because it really is that simple to correct.
Please, if youve got no experience with this problem, then dont post as it offers no real help.
I cant really explain it simpler than this. Hopefully someone will benefit from my post.

Blah blah blah blah, I agreed with you there and just gave clarification to all that DPI has nothing to do with it.
Love you too.

I am able to confirm that nvidia3dvision's suggestion is the actual fix for the grid like mouse movement problem in BF2.
I tested with my actual ingame sensitivity of 1.9 this caused mouse jumps of over 8px and was significantly visible. I then lowered the ingame mouse sensitivity to 1.0 which improved the skip but was still at around 5px. Changing the ingame sensitivity to 0.1 brought the ultimate improvement and there was no more skipping, it was actually ~1px movements.
However I would like to mention that the decreased ingame sensitivity has strong effects on gameplay due to slower turning. I could compensate this by maximizing the on-the-fly sensitivity of the mouse (driver program) and increasing the sensitivity in windows mouse settings. I also suggest trying out if one can work with accelerated mouse movements.
-> actual solution was to lower the ingame sensitivity as much as possible (still playable)

Timely thread for me, I picked up a Logitech G5 this week to replace a failing MX518.
Spent a couple hours in stand alone co-op trying to take advantage of the higher dpi.
The jumping is much more noticeable when turning down the mouse dpi using the button and increasing the in-game option.
I'll now try it the other way around as suggested - I was hoping to use the on-board mouse high DPI button setting when in tanks/AA but I'd rather have smoother infantry aiming.
Thanks,
