Why do I need Notepad++ for this?

The author warns that editing the files with the regular Windows Notepad breaks the game, so use Notepad++ or a similar editor.

Any number from 22 to 999. The author used 144 to match a monitor refresh rate, and 999 unlocks the range completely. The value must match in KFEngine.ini and KFGame.ini.

How to Remove the KF2 FPS Limit of 62 (KFEngine.ini and KFGame.ini)

By default Killing Floor 2 limits the frame rate to 62 FPS, which is low for modern PCs. This Russian community guide, based on an English guide by Fastie, shows how to raise or remove the cap through two ini files. See also another FPS lock removal guide.

FPS before the change Before: capped around 62.

FPS after the change After: a much higher frame rate.

Important

Use Notepad++ (or another proper editor). Editing with plain Notepad breaks the game.

Steps

Open C:\Users\<name>\Documents\My Games\KillingFloor2\KFGame\Config (on some systems Documents\KillingFloor2\KFGame\Config).
Find KFEngine.ini and KFGame.ini.
Open KFEngine.ini with Notepad++ and find the [Engine.Engine] section.

Engine.Engine section The [Engine.Engine] section.

In it find:
- bSmoothFrameRate=TRUE
- MinSmoothedFrameRate=22
- MaxSmoothedFrameRate=62
Replace 62 with any number from 22 to 999. The author set 144 to match the monitor's refresh rate. 999 fully unlocks the range. Keep bSmoothFrameRate as TRUE; setting it to FALSE together with 999 removes all limits, but the author does not recommend it because the game becomes less smooth. Work only in the [Engine.Engine] section.

Edited values Edited MaxSmoothedFrameRate value.

Open KFGame.ini and find the [KFGame.KFGameEngine] section.

KFGameEngine section The [KFGame.KFGameEngine] section.

Find MaxSmoothedFrameRate=62.000000 and MinSmoothedFrameRate=22.000000. Replace 62 with the same number (22 to 999), leaving the zeros. It must match the value in KFEngine.ini. Save.

Edited KFGame.ini The matching value in KFGame.ini.

If the game broke

Go to Documents\My Games\KillingFloor2\KFGame and delete the Config folder. It is recreated at the next launch and the settings reset.
