Mouse Acceleration

The game defaults to raw input, which does not support mouse acceleration. In game this is shown in the mouse options by having the Mouse Acceleration option greyed out. Raw input can be toggled by editing SeriousSam2017.ini.

Edit SeriousSam2017.ini[citation needed]
  1. Open SeriousSam2017.ini in the configuration file location using a text editor.
  2. Change the following line to toggle raw input (Change to = 0 to disable): inp_bRawInput = 1; _(version="2")
  3. With raw input off, mouse acceleration will still be disabled by default. Use the following console command entry to enable: prj_bMouseAcceleration=1


  • The game does save most console commands to the .ini, but not this one. It also seems to ignore it in startup scripts, so there is no way to save this functionality, the command will need to be run again after every startup.
  • If the game crashes it tends to revert SeriousSam2017.ini to "safe" settings, which includes reverting any changes like the above. Setting SeriousSam2017.ini to read-only can prevent this.

    "Just a heads up on Serious Sam Fusion 2017: disabling the Software Mixer to use OpenAL Soft's HRTF also seems to disable reverb. Parts that I know had reverb originally (like the opening platforming section in the 2nd Palenque level in TSE) were dry. I'll have to do more testing on this, but it's just something that's worth noting."
