Issues fixed

Nvidia FleX is greyed out

This is usually caused by the graphics card not being supported or detected wrongly. It is still possible to forcibly enable the Nvidia FleX feature, however system requirements for this feature increase. The new requirements can be found underneath the Nvidia FleX setting in-game or under the System Requirements section on the page here.

Edit Configuration File^{[citation needed]}

Go to the configuration file(s) location.
Open GFXSettings.KFGame.xml.
Find the line starting with <OPTION Name="Flex", which should be located at the bottom of the file.
Change the two lines to <OPTION Name="Flex" Registered="True" Type="Integer" Value="2">, <RANGE MinValue="0" MaxValue="2" NumSteps="2" />.
Save the file.

Notes

Value="2" will control the setting, 0 meaning disabled, 1 meaning gibs and 2 meaning gibs and fluids.^{[citation needed]}
