Browse to MWO installation directory. It should be something like this:
"C:\Games\Piranha Games\MechWarrior Online"
Open "user.cfg" file with your favourite text editor (eg. notepad)
Copy-paste following lines to the user.cfg file, save the document and start the game
## mouse sensitivity cl_sensitivity = 0.20 ## mouse acceleration off i_mouse_accel = 0 i_mouse_accel_max=0 i_mouse_smooth=0
Depending of your mouse you might want to change the "cl_sensitivity = 0.20" either to lower or higher value. Try with 0.30, 0.10 and find your own preferred setting. For me 0.20 is the most comfortable with dpi of 600.
By looking the code you have probably noticed that I have disabled mouse smoothing and acceleration (it gives me more natural feel to the actual game-play). To enable the default mouse acceleration, either delete everything under "## mouse acceleration off" or add "##" before each line you want to disable.
To reverse the settings to defaults, delete the mouse relevant code from the user.cfg file.
If you have problems editing user.cfg file, please check this thread.
Possible side effects:
Sometimes when you move your mouse rapidly before starting a match, your arm cross-hair (the small circle) might be positioned to somewhere else than to the centre. This is a cosmetic side effect. The true cross-hair is there -- on the right position, but the thing is, you can't see it in your HUD.
Possible workarounds for side effects:
- Don't move your mouse during game/match launch
- Don't modify user.cfg file and/or if you have, revert user.cfg file to the original
- Buy a gaming mouse which can handle dpi value shifting.
