Is it possible to force 'mouse acceleration' behavour off in all PC games?

I see it a lot these days.

In my newest game Fallout New Vegas it only occurs in the menus and pip-boy, thank og. It’s where normal movement of the mouse causes the cursor to move at a glacial pace, then a very tiny increase in physical movement speed causes the cursor to fly across the screen at four hundred billion miles per hour.

This may or may not be a symptom of the games being made on consoles and ported to PCs, or made for gamepads and not properly adapted for mouse movement. I accept that the couldn’t-care-less-about-the-small-market-of-pc-gamers game producers probably won’t stop doing this any time soon. So…

Is there a way of ‘hacking’ or bodging the OS or game itself to cause the mouse movement to behave normally?

No. Sometimes it’s hard-coded into the game engine, as is the case for Fallout 3/NV and the Gamembryo engine.

In case you weren’t aware, you can change some settings in a couple of *.ini files to get rid of it in Fallout:NV. I know you did ask but I’d hate someone to have to needlessly suffer the terrible mouse acceleration in that game.

Happen to know which setting to change?

As I say, it is only a problem in menus and the pip-boy. Outside of those there is no problem (except for the sporadic pausing and fps-slowdown, which I’m sure they’ll patch soon)

But I’d still like to eliminate it if it’s possible :slight_smile: It is annoying not being able to use the pip boy as ‘efficiently’ as I can use a typical windows app with the mouse.

Open Fallout_default.ini in C:\Program Files (x86)\Steam\steamapps\common\fallout new vegas

Scroll down to [CONTROLS] and add the following:
fForegroundMouseAccelBase=0
fForegroundMouseAccelTop=0
fForegroundMouseBase=0
fForegroundMouseMult=0

Do the same thing to Fallout.ini and FalloutPrefs.ini in C:\Users***\Documents\My Games\FalloutNV.

That should do it. Those locations are probably different if you don’t use Win7 64bit but hopefully you can find them.

Good hunting.

Will give that a try when I get home tonight. Thanks :slight_smile:

I don’t know why the hell they even give the option for mouse acceleration. What sort of backwards ass ape-man would want it that way?

It works. Thanks!

Now I have to un-get-used to the acceleration and get used to it working properly :smiley:
Now if only the devs would fix the damn npc slowdown issue (seems to only affect the game on windows 7 65 bit according to forums)

I could understand it if you were already used to mouse acceleration in your OS, but then why not use the exact settings from the OS?
