The Evil Within is locked at 30 frames per second on the PC. However, you can change that through one of the game's many cheat codes.
You can access the horror game's cheats by enabling the debug console. You can do this by right-clicking on The Evil Within in your Steam library, and then selecting "Properties." In the General tab of that window, select "set launch options." Once you're there, enter the following line without the quotation marks: "+com_allow console 1"
After that, you're ready to launch the game. At any time, you can press the Insert key to open up the developer console. These are the codes that you can use, according to Bethesda:
Noclip: Allows you to walk through walls
G_infiniteammo: Unlimited ammo (provided you have at least 1 bullet when you enable this)
G_stoptime 1: Stops time. Note there is a bug right now where using this command causes a UI element to appear on screen. We’re looking to fix that in the near future. Re-enable time with g_stoptime 0
Toggledebugcamera: Separates the camera from Sebastian so you can freely move around.
Com_showFPS: Turns on id’s native FPS counter
Startslowmotion2: Slows down time
Stopslowmotion: Disables slow motion
Bethesda warns that their customer service won't be able to help you with issues resulting from these cheat codes. While they realize that PC gamers might want to push the game's performance, they recommend that you don't do so.
"Shinji Mikami and the team at Tango designed The Evil Within to be played at 30fps and to utilize an aspect ratio of 2.35:1 for all platforms," Bethesda said earlier this month. "The team has worked the last four years perfecting the game experience with these settings in mind."
Added Bethesda: "These commands and changes are not recommended or supported and we suggest everyone play the game as it was designed and intended for the best experience."
The Evil Within launches today in North America and Europe on PC, PS3, Xbox 360, PS4 and Xbox One. If you're planning to play the game on PC, you can find the system requirements here.
