Mouse DPI / Accuracy / Sensitivity issue

Aside from advising people to get expensive gaming mice, and the debate around it; is there any more info about this issue at all? So far Grim is the only person to have demonstrated any comprehension of the problem, and quite frankly I found his posts to be pretty abstract to the point where I couldn't say authoritatively how plausible his explanations to be.

Until you provide some information I doubt that you will get a resolution to whatever perceived issue you have.

Find a ruler and go ingame. Report how many inches or centimeters you need to complete a full 360 rotation. I hope mouse acceleration is off, because you will get inconsistent results with it on.

Provide all the correct units and such for your measurement.

As a point of reference, I use about 38 degrees/inch (15 degrees/cm) in MNC. This is pretty high for something like CS or TF2, but in MNC it's pretty forgiving. If I ran accuracy endorsements I'd use much lower probably.

My guess is that you have your sensitivity at such a high setting that you are seeing the minimum angular turn required by the settings you use. But without knowing your settings it is impossible to say.

i do a 360 in about 1inch maybe a bit more, is that high or something? since i am fairly new to pc gaming, i thought they just ran really high sense and got used to it.

That's pretty insanely high even for MNC. Think of degrees per inch as having an inverse correlation to physical size of your target on your mousing surface. The larger this is the easier it is to actually get your mouse into that location precisely.

In MNC this doesn't matter as much as something like Quake, CS, or TF2 but it still governs how accurate you are with the weapons.

From a few discussions with CS players, they use something around 20-30 degrees/inch (or lower!). Lower is better for precision. The cost of moving a mouse farther to turn around is mitigated by knowing the game flow and just being aware of where enemies are possible to be at any given point. There is a point where going lower does you more harm though. As you get really low, you can't react at all to unexpected circumstances and this in turns hurts your overall effectiveness even though you absolutely smash anything expected.

There is no option to turn mouse acceleration on or off (I've reverted back to the default settings of having mouth smoothing off via the ini file) in the game's menu.

At MouseSensitivity=36.313332 which isn't 100% perfectly precise, but I'd consider it "suitably precise", I do a 360 in 13 centimetres; about 27 degrees per centimeter.

In DOD, I'm Doing a 360 in 8cm; about 45 degres per centimeter. And yet, in DoD my accuracy is pixel perfect.

However, I think this is the heart of the issue - in DoD:S, even though I have mouse smoothing, mouse acceleration and mouse filtering unticked; the rate at which I turn is contingent on the speed with which I turn the mouse. If I move it along the mousemat at a slow and steady pace, I don't even do a full 360 before I run out of room on the mouse-mat. If I move it quickly, I can do more than a 360 and still have room to spare.

The issue does seem to be about one of acceleration. No matter the speed I move my mouse in MNC, the degrees per centimeter stays at a constant.

However, I do have an issue with Source engine where some of them won't let me use raw mouse input (If I tick the box, I can't turn left or right with the mouse at all). Which is fine, as the settings I have are perfectly suitable; giving me perfect fine tuning when I move with slow precision; and rapid turns when I want to look around quickly.

MNC doesn't offer me this utility, unlike pretty much every Shooter I've played in the last ten years.

That has generally been my assumption from the get-go; looking at it I'm pretty sure the problem is no / terrible mouse acceleration, which means you have to crank up the sensitivity beyond an acceptable minimum to get the full speed of movement.

If it is possible to disable raw mouse input via the ini files, then I could test the hypothesis that raw input combined with no acceleration is to blame.

If it is possible to enable acceleration in the ini files, then I could test the hypothesis that there is no / insufficient acceleration irrespective of there being raw mouse input, combined with artificially high sensitivity to blame.

You probably have acceleration enabled in Windows.

Try turning that off?

Your sensitivity is definitely lower than where you'd expect to see minimum angular distance problems though.

It seems that you like mouse acceleration for some reason. Predominant (hugely so) wisdom as you go up the skill ladder in FPS games says mouse acceleration is always a bad choice. Personal preference I guess but with such a majority there is probably something to it.

70 degrees/inch isn't outrageously high, but still pretty high. It's probably fine in MNC if you are used to playing that high though.

I like to be able to do precise aiming without having to smack my mouse into my PC case in order to do 360s.

CSers who like the low move speed so they can do the equivalent of "centre-view-headshot". The slower the mouse, the less likely you are to move it off the sweet-spot.

However, I think I've had a Eureka moment.

Seem to have massively improved the issue.

well my deathadder died, what would you guys recommend as a good mouse? around the 100AUD price range?

I still use my 6 year old MX518 and if this dies in the future, I will buy it again. Just to perfect.

yeah i came to the decision to get one, i just need to go the shop after school and swap it, get some money back but not much, i would buy online but no money in paypal, god damn this

A great deal of professional Quake players actually use mouseaccel.

It's preference, practicing with accel on is detrimental to developing muscle memory as it's harder to grasp for most but accel allows for nice accuracy on slow move and good rocket jumps on flicks (talking about quake)

Some like noctis also have different settings per gun.

For newcomers or inexperienced people however it's best to play without accel and with a setting that doesn't change for years - allows some good development.

Aim for 7 to 12 inches per 360 (most professional players are within that spread)

For reference:

I use a Steelseries Xai (wouldn't buy because of the Price, but my sponsor gave me one) on 400 CPI without acceleration (EPP turned off, Windows 6/11), 500 hertz.

tl;dr: No accel unless you're really good, pick a setting and stick to it.

gonna take some time before im used to the mx 518 but it better be worth it
