Negative Mouse Acceleration

[XanthosAcanthus]

First Max Payne 3 and now Far Cry 3. This year kinda sucks for mouse users. With all acceleration disabled, there is noticeable negative mouse acceleration, especially at lower sensitivities. Is there any way to fix this? Has it been acknowledged as a problem?

I really hope it gets fixed, because it is driving me crazy. Rockstar never fixed the issue in MP3 and even refused to acknowledge it as a problem(it funny because in all of the multiplayer events for PC, all the rockstar devs have used controllers)

Why Ubisoft, why? Raw input should be top priority for pc released IMO.

Noticed it; had to raise my sens to keep my sanity. I don't know of any fix :(. I know some guys tried to apply positive acceleration to balance things out, but it didn't work too well.

[XanthosAcanthus]

Did some testing. The vertical movement feels right, but the horizontal axis is what gives you the slowdown. It feels like some sort of maximum speed limit.

It's just a bad port. Better than the worst, yet not the best. What ever at least they gave us fov right? Aside from MSAA being bugged for some and weird glitch's and hacking and what not.

Go to: C:\Users\USER\Documents\My Games\Far Cry 3
Open the file "GamerProfile.xml" with a text editor. (google notepad++)
Under the <ProfileSpecificGameProfile line, look for the string "UseMouseSmooth="0" Smoothness="0.2" Smoothness_Ironsight="0.2" and simply change the values to 0.0

I definitely feel a change in smoothing after these small changes.

hmm it seems to only make a difference in windowed mode, sorry

This needs serious attention, we must bring further attention to this issue. Ubisoft usually delivers if the demand is high enough.

Horrible to hear you're getting this.
I HATE negative acceleration. I was able to get a refund on max payne 3 because of it.
Oddly, I never experienced any negative acceleration in FarCry 3, so I can't offer any advice.
Have you tried all different video settings?
Do you have a controller plugged in that might be interfering?

[Rocko]

As far as I know, a lot of people don't notice the negative accel in FC3 simply because it's not a game that requires fast reflexes. Do a test real fast. Move your mouse a certain distance slowly, observe how much you turn. Then do it the same distance quickly. Boom. Should have negative accel.

I do quick 180 turns in Far Cry 3 with no issue. I haven't noticed any negative acceleration.

What I am concerned about is the seemingly jittery, low-DPI mouse movement inherent to the game. When I turn up the sensitivity, I lose a lot of precision, making it hard to aim at little enemies off in the distance. I played another FPS, Hard Reset, recently, and in comparison, the DPI/precision felt much smoother at high sensitivity.

Mouse smoothing turned off in all games, so that's not the issue.

The negative acceleration is related to the in-game sensitivity. In other games, the symptoms you describe are usually solved by maxing out your mouse's DPI and lowering the in-game sensitivity proportionately. However, with the way this game implements negative acceleration, the lower you set the in-game sensitivity, the slower the maximum look speed is.

The minimum the game will let you set in the GUI is 0.4, and is still way too sensitive for my mouse at its maximum DPI of 5600. The negative acceleration at 0.4 isn't too terribly intense, but it's still definitely present. Kicking down the DPI to around 1800 makes the sensitivity feel closer to the right aiming speed, but then I begin to notice the jittery imprecision you mention when trying to aim finely. So I opened up the settings file in a text editor and changed the game's sensitivity to 0.1 and cranked my DPI back to 5600. This solved the lack of pixel perfect precision, but made the negative acceleration absolutely unbearable, like the video shows.

I can understand developers wanting to introduce a maximum plausible turning speed for a 200lbs man carrying a LMG with 500 rounds and a half dozen grenades. But the way that maximum speed is bound to the sensitivity setting just makes obvious it was designed for an analog stick with its limited scale of range, and no more thought was put into it. I mean you can raise the sensitivity and acceleratoin and spin faster than a helicopter rotor. So it's definitely not an attempt at realsim. Just give us raw, Ubisoft!

The negative acceleration is a joke. It's unplayable for me. Gonna demand a refund.

Just wanted to let everybody know there's a fix[pcgamingwiki.com] out. It's a bit of a hassle but well worth it.

Actually it works the other way around: higher DPI and lower game sensitivity lower the negative accel threshold (bad), at least for Quake engine based games. What you are referring to is that at high sensitivities (overall, not the game value) like 5200 @0.4 you need a minimum amount of DPI to have pixel accuracy, you were much likely under that limit. I play 400 DPi @0.4 and it's still a bit faster than my cod4 or bf sensitivity, pretty ret.arded..

This fix should also work with the original Far Cry 3. Just in case anyone was still looking for a solution.
