Mouse Acceleration!

[Spuzaw]

Fear 2 has terrible mouse acceleration. Anyone know if it's possible to disable this?

I couldn't find a solution anywhere. I'm not going to waste my time playing this game if I have to deal with these terrible controls.

Figured it out!!!

I knew for fact I had mouse acceleration and that it wasn't a problem with my hardware. So I was testing the mouse accel again in FEAR 2 and noticed it wasn't a problem with accel at all. When I looked closely it turns out slow mouse movements were skipping, the slow movements weren't fully registering in FEAR 2. So this made it appear as mouse accel when it was actually just bad detection of slow mouse movements.

Now I knew what problem was I just didn't know what could be causing it. Then I remembered the first thing I always turn off in games is Vsync. I have a very powerful computer so I'm getting extremely high frames in FEAR 2. So I was thinking maybe the high frames are causing the game to not read mouse movements properly. As it turns out that was exactly the problem, the mouse acceleration is gone!

Now my only problem is that I hate vsync because it causes input lag (that's why I always turn it off). So I'm going to need to find a way to limit the frames without vsync. That's no big deal though, now it's at least playable.

tl;dr

Turn on Vsync if you experience mouse acceleration in FEAR 2.

Update 2:

I figured I'd update this thread one more time for anyone that stumbles onto this problem and is looking for a fix.

I used Dxtory[dxtory.com] to limit the game FPS to 60 so I could turn off Vysnc. Now it's smooth as butter. No mouse acceleration, no input lag. Perfect mouse movement!

There's other programs out there that can put a cap on your frames but Dxtory is the one I decided to use.

---------

So here's the short summary of it all:

• Having a higher frame rate than 60 will cause the mouse to not register slower movements.
  
• The solution to this problem is to cap your framerate to 60.
  
• You can use Vsync to accomplish this but Vsync causes input lag.
  
• So I recommend using a program like Dxtory[dxtory.com] to cap the FPS to 60 and then turn off Vsync.
  
• To cap your FPS with Dxtory go to the advanced tab (microchip). Then checkmark "Limit Video FPS" and set the number to 60.
  
• Your mouse problems are now gone!

If you have an NVIDIA card, you can also do this by going to NVIDIA control panel -> 3D Settings -> Manage 3D settings, open the Program Settings tab, select F.E.A.R 2 (fear2.exe) and set the Max frame rate there

For a different fix without having to enable Vsync or framerate max options , try

https://www.highrez.co.uk/downloads/XMouseButtonControl.htm

I used this to not only modify the mouse acceleration but allow me to key bind grenade and slow motion to my mouses button 4 and 5 ( by simulating the original key presses ). Something to try if you dont want to enable Vsync or limit the frame rates. It has to be running when fear2 is running.

I use the portable version and is working fine for the first hour or so

Bois found a solution. I'm using MadCatz R.A.T. 6+ mouse and dis game was unplayable with it. Tried patching as stated above, but mouse perforemed even more wierd. So I just unplugged it and plugged cheap Logitech B100 and now it works like a charm.

Guess it's smth about game calculating dpi wrong. Anyway just try a simplier mouse if u rly wanna play this relic.
