You can push the PC version of The Evil Within beyond 30fps with the use of debug commands, publisher Bethesda has confirmed - but the publisher advised against doing so.
Developer Tango designed The Evil Within to be played at 30fps with an aspect ratio of 2.35:1 for all platforms, Bethesda said in a forum post. And so the PC version locks to these settings automatically.
You will be able to alter them, but it seems that doing so may affect the game's performance in other areas.
"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.
"The team has worked the last four years perfecting the game experience with these settings in mind. For PC players, we'll provide debug commands on how you can alter the frame-rate and aspect ratio, but 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."
Elsewhere, Bethesda confirmed that on PC you can disable the letterboxing featured in the game. But, again, it's not recommended.
"The letterboxing (a 2:35:1 aspect ratio) is used for gameplay purposes, as certain elements display in the black areas of the screen," Bethesda said.
"On PC, you can turn off the bars and force the game to render full-screen. However this option is not supported. We're keeping the ability to turn off bars as a console-only command that we will share at launch."
Earlier this month Bethesda confirmed the minimum and recommended specs for the PC version of the game.
