Mouse acceleration question

post #1 of 8
Thread Starter 
So I was wondering what exactly causes mouse acceleration to kick in?

Is it the physical distance the mouse has traveled on its surface?
Is it from travelling a quick speeds?
Is it affected by sensitivity/DPI?

I ask that because I was also wondering how acceleration interacts with sensitivity/DPI settings. For example, because you don't have to move the mouse as far physically when you use a high DPI setting (assuming you're on 6/11 sensitivity), will acceleration still kick in as much?

From some tests that I've seen, people move their mice over quite a long distance such as back and forth on an entire mousepad to test acceleration. If I game at relatively high sensitivity (let's say for example 2000-3000 dpi on 6/11 with high enough in-game sensitivity), will acceleration affect consistency very much?

Been thinking about the Sensei Raw for because I'm looking for a fingertip mouse of its shape and unfortunately the Kinzu v2 Pro sensor was just not good at all. I know people always talk about consistency issues with laser sensors and acceleration, but just how much does it really affect consistency outside of low sensitivity gaming that requires you to move your mouse over long distances physically?

There is no need to over analyse it. Mouse accel kicks in whenever you move the mouse if the game you are playing has it enabled. Sure, speed of the mouse can make things feel different, however you need to just find the right balance that works for you!

I for one disable mouse accel in games that allow me to do so, then I set a low sensitivity in the game options, followed by 800 dpi on the mouse and I use the 6/11 mouse setting in windows.

Ah my bad I should've been more clear. I was wondering because there are mice with good shapes but a laser sensor which has built-in acceleration that can't be disabled. Personally I do prefer a 1:1 movement so of course I disable any acceleration as well but it won't be possible with the laser mice. That's why I felt that I should ask how much of an impact laser sensors have on accuracy, and how/if different ways of moving the mouse and different sensitivities/dpi/etc affect it.

Acceleration can be added at the hardware or software level, but it seems you are concerned about the hardware acceleration of the Avago laser sensors. The graph that gets referenced all the time is this one:



On this graph, the vertical axis is the percentage of the counts the mouse is "supposed" to have: dots above the line represent positive acceleration and dots below the line represent negative acceleration. This is for one mouse and one mouse pad, but the issue is similar across 9xxx-sensor mice and across pads. The Sensei is a bit better than the Xai in this manner, and in the brief time I had a Sensei RAW I didn't notice any negative acceleration -- only positive.

The primary cause (by definition) of acceleration is the speed at which you move the mouse -- it's not that high-sens players move their mice shorter distances per se but that they generally move their mice at slower speeds. In my personal experience, it was starkly noticeable on the Sensei RAW playing at 25" per 360 turn. However, the high sensitivity players I know that use Avago laser mice generally don't find it troublesome to the point that they don't even know what I'm talking about when I mention acceleration.

These are players that use 6" or less to turn 360 degrees, and in most modern military shooters (or anything with iron sights really) it means ~12" to turn 360 degrees while aiming. At this level you may notice the acceleration, but mouse movements while aiming down iron sights are usually not too quick unless trying to pick multiple targets at a wide angle.

At the end of the day it is down to your own perception. I should mention that Steelseries is releasing a Kana v2 using the most popular/'best' optical sensor within a month or so, so if you're not in a hurry it may be worth looking into. If you are in a hurry, give the Sensei RAW a try from somewhere you can return it. I was a big fan of the shape, weight and overall feel, just not the sensor for my playstyle.

Hopefully that helps!

I'd shop around for a mouse that does not add much or no accel at all. The G400 seems very good mostly, which I use right now!

One mouse you may not have considered is the Zowie FK. It is a light, ambidextrous optical mouse with no acceleration or prediction. My only complaint is that it's a bit too small for me, but if the Kinzu size/shape was okay for you, it could be a very viable option.

Immensely, thanks a bunch! I think I'll try a Sensei or Sensei Raw and see how that works out.

I've actually tried and returned a G400s. The shape was just no good for my fingertip grip.

I'll probably look into this one later.

With the avago 9800/9500 mice, the only way to really know is to try. Get a Sensei Raw or Xai--whatever they still sell--and preform your own accel tests. Return it if you're unhappy. If you don't want to worry about it, wait for the Kana V2, get a Zowie FK or AM, or try a different shape.
