Uninstall Geforce NOW from your pc

Put -dx11 in launch options, Add -dx11 to the shortcut exe file

How to do that

1-Right click the game in your steam library > General > type -dx11 in your launch options

2-If you want to change it in the game files you need to

Right click the game in your steam library > Local files > Browse > Right click KOFX_Steam.exe > Create shortcut > Right click on the shortcut > Properties > In the target at the end of the sentence add a spacebar and -dx11 so it should look like this at the end KOFXV_Steam.exe" -dx11 (THIS IS ONLY THE END AND NOT THE FULL SENTENCE REMEMBER) the quotation marks need to stay there > Click apply > Close all the tabs and try starting the game

For me it didnt start at all and uninstalling Gefore NOW helped.

Hope this helped :)
