Other than that, good luck and have fun flying around Amnesia, Half-Life style! Hint: Wait until you're able to jump in Rainy Hall before entering Old Archives! Running and jumping is encouraged, meaning you have the added challenge of avoiding hitting your head on things. The rationale for these settings is that the ratio of ground and air movement is changed, meaning you move faster if you run and jump. (You may want to use CTRL + F to find these entries) GravityForce = '0 -10 0' (default is -20) Make sure you back up the file! If you don't have a backup and messed up the config, then verify the game cache using Steam and it'll redownload that file (along with everything else you changed, meaning you have to unpatch again). The config file we change is in Steam\steamapps\common\Amnesia The Dark Descent\config\game.cfg Inspired by a recent F3 fast forward playthrough of this game by Nosferatu on stream, I've had the idea to change a config file of this game to speed up the movement and to lower the gravity for fun.
