KF2: Unlock FPS Above 62 for 120/144 Hz Monitors

Killing Floor 2 ships with a frame-rate limit of roughly 62 FPS, which wastes a 120 Hz or 144 Hz monitor. This short guide shows the two INI edits the author used to lift the cap and play above 120 FPS. A video walkthrough was published with the original guide.

Video cover: the author's walkthrough of the FPS unlock (https://youtu.be/zdYTopvwyCY).

What you need

• A text editor. The author recommends Notepad++ because it makes search-and-replace in config files easy, but any editor with a find function works.
• Windows 10 was used in the guide; other Windows versions should be similar, you may just have to navigate to the folders slightly differently.

Where the files are

Open Documents > My Games > KillingFloor2 > KFGame > Config. You need two files from this folder:

• KFGame.ini
• KFEngine.ini

Close the game before editing, and keep a backup copy of both files.

Steps

1. Open both files in your editor.
2. Search for bSmooth. Change every True you find to False. Use "find next" until you have changed all matches in both files.
3. Search for SmoothedFrameRate. The maximum value is 62; change it to 122 or 142 (or whatever you want just above your monitor's refresh rate). Repeat the search until every matching line has the same value.
4. Save both files and launch the game.

If everything worked, players with 120 Hz and 144 Hz displays should see a noticeably higher frame rate than before.

Notes

• The cap is a smoothing feature of the engine, so values above your actual hardware limit simply have no further effect.
• The author also states the same format works in Rising Storm 2: Vietnam (same engine), reaching above 80 FPS in his own tests, though the config folder lives elsewhere.
• If the game ever overwrites your changes after an update, repeat the edit. For general graphics tuning see also FPS tweaks via INI.
