A couple days ago I changed my in-game sensitivity to ~67%, and I noticed it felt quite strange. Jump forward to today, while alt-tabbed from SC2 I noticed my mouse sensitivity was the same in Windows as it was in-game, so I checked the mouse sensitivity in the control panel -> mouse window, and lo and behold it is about 8/11. As some of you may know, putting your Windows mouse sensitivity above 6/11 results in a huge loss of precision.
I really don't understand why it doesn't use DirectInput (or even better, raw input ala QL/CPM), and use a real in-game sensitivity like Quake/Quake3, etc. can. You can notice the effects on your own PC by putting the slider to 6/11, drawing some curved shapes in pbrush, then changing it to 11/11 and comparing the two. e.g.

TLDR: Don't change in-game sensitivity (unless Blizzard fix it) or your windows sensitivity. Buy a mouse with higher DPI or use a lower resolution. |

| Thanks for the post.. Definitely informative and I am sure people change their in game settings without noticing this. |

| Testing right now. i personally had to turn up my in-game settings but perhaps i should have stuck with the razer drivers. |

| So in SC2 we should leave it/put it at 50%? |

you should never change your windows sensitivity from default - this is pretty well known
50% is matching windows sens but in the end you either want Blizzard to do it the right way or get a mouse with changeable DPI |

| yea always leave windows sensitivy at 6/11 and in-game sensitivity on 50%, and get your mouse sensitivity how you like it by adjusting your mouse's dpi. That way you always have a 1-1 pixel precision. |

Good find. If you set your Windows mouse precision higher than the middle setting, then for every pixel that your mouse reports moving, Windows will move the cursor (1.5 / 2 / 2.5 / 3 / 3.5) pixels for the 7th-11th settings, respectively. In other words, if you set your mouse setting to 8/11 it is impossible to land on an odd-numbered pixel!
The middle (6/11) setting is 1 to 1 and is safe to use. |

Yes, 50% in-game and 6/11 in Windows (the middle/default setting) will give you a 1:1 pixel-accurate cursor movement. |

| Yeah, when I installed SC2 after beta ended I noticed my mouse sensitivity was WAAAYYY low... so I cranked it up to 85%... and then when I switched back to BW after finishing placement it was WAAYYYY high... it was 11/11 in the windows slider -I usually keep it at 7/11. |

What? Witchcraft!
Testing it now. Didn't know about this 1:1 pixel deal. |

Of course you don't NEED it. We didn't NEED to get rid of dusty balls in our mice either but people like to use what's better. |

Yes, 50% in-game and 6/11 in Windows (the middle/default setting) will give you a 1:1 pixel-accurate cursor movement.
This (I think obviously) only applies if Windows and SC2 are the only programs modifying your sensitivity.
If you're using, say, Razer drivers, it gets a bit trickier. |

Yeah, I don't have a Razer mouse here so I can't test, and I'm unsure of how the Razer mouse sensitivity setting works. If you put your Windows to 6/11 and put the Razer sensitivity to full, and try something in pbrush like the image above you should be able to tell if it's the same pixel-jumping method or if it's something a bit more stable/precise. |

The reason the mouse skips pixels is because you don't have "enhance pointer precision" (I hear this is some form of mouse acceleration, maybe not good for some people, but I like it)
I usually have windows sensitivity high (or possibly maxed), checkmark "enhance pointer precision", and use the DPI I want on my mouse (which is the max of 2000, or sometimes 1600). Obviously you can choose non-max windows sensitivity, but even then you should select "enhance pointer precision" as far as I know.
On a different, but related note:
Anyone know what "reduce mouse lag" in SC2 does? Anyone noticed a difference? which do they prefer?
I do know on my old computer, when i played against 4 AIs and my machine slowed down to like 1-3FPS, my mouse clicks and stuff wouldn't register really. Perhaps that has something to do with that setting (it was disabled).Last edit: 2010-08-07 17:57:22 |

wait... we got rid of those? FFFUUUU!!!!
on topic: Testing this... sounds VERY interesting..
Edit: T.T ... WOW! I see what you mean by putting it on 11/11, the mouse like skips a few pixels, no, a LOT of pixels... well this helps narrow some choices for future purchases ... thanks!Last edit: 2010-08-07 17:47:13 |
