Mouse Acceleration[edit]

  • Latest version: (version 3.0.3 / 440323 as of 2022) 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. You can turn off raw input, or make sure it's on by editing SeriousSam2017.ini
    • Change this line to toggle raw input (Change to = 0 to disable): inp_bRawInput = 1; _(version="2")
    • With Raw input off, mouse acceleration will still be disabled by default. Use this console command entry to enable: prj_bMouseAcceleration=1
      • Note: 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, you'll have to run the command again after every startup. Better to just keep on raw input if you want mouse acceleration disabled and the smoothest mouse look experience.
      • Also Note: The game is still a bit unstable on modern machines, if it crashes it tends to revert your .ini to "safe" settings, which includes reverting any changes like these. So if you want them to stick, set your SeriousSam2017.ini to read only so the game can't do this.

  1. Disabling the software mixer to use OpenAL instead also disables reverb.[4]

  4. @Apocryph Wiki Master#3423 (I Drink Lava) on 3D Game Audio Discord server - last accessed on 2019-04-06
    "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."
