Mouse accuracy?

Pete.Dakota · 9 Oct 2010 at 19:12

Something that's ALWAYS annoyed me about FPSs is a seemingly poor mouse accuracy, making aiming feel sluggish.

The best way to explain it is thus:

In a game, say BFBC2, the smallest registrable movement of the cross hair is more than one pixel; I think it's about 3 or 4. So while sniping from a distance, trying to line up on someone's head is nearly impossible. If the crosshair is too far left, making the smallest movement possible to the right moves the pointer too far and I'm on the right side of my target.

On my desktop the smallest possible movement I can make is one pixel. But in games it's 3 or 4. This gives the impression of a poor frame rate almost, and aiming generally feels awful.

Would a higher DPI mouse fix this problem? How does mouse/pixel accuracy work?

You have to match DPI, horizontal pixels and FOV as well as the mouse sensitivity/multipliers to make sure its mapped 1:1 or better. You may also find you need to turn off mouse acceleration or "enhance pointer precision" type features and even adjust the windows acceleration curve to get best results.

Also this is often a side product of so called "gaming mice" many high DPI gaming sensors are actually very bad. If you can deal with the shape try something like the DeathAdder with its proper high DPI infra-red sensor.

Mine's just a basic Logitech wireless mouse that came in a keyboard pack.

How do you do this matching you speak of? Is there software for it? Or is it a case of buying a decent mouse and hoping the game likes it..

You can use something like this to try and work out settings the work best for you - ideally based on the distance you move the mouse to turn 180 degrees.

That site says my required DPI is 1525. So I should hunt down a 1600dpi mouse?

Its not as simple as that the site is a guide at best - theres a big thread on how to work it out for best results on here somewhere if I can find it - someone posted some really good advice.

lower the settings in windows control panel to make it in the middle

Some good info there from D D Danneh - as above for 1:1 mapping you need to set the windows mouse sensitivity to the middle (or 5 or 6 can't remember which number off the top of my head) and same sensitivity ingame.

Well first off I've simply tried getting used to a lower sensitivity. I've pretty much halved it, and it's feeling OK. It's still not 1:1, but may put me off buying a whole new mouse if I can stick with it.

Maybe if I wind up with the money at some point. New mobo first!

Or if you get something like the MX518 it has hot swappable DPI settings so you can adjust your DPI in game at the touch of a button, one setting for moving round then swap for sniping mode, works pretty well
