RivaTuner doesn't work with Metro Last Light Redux

Hello, first of all, I have to precise that im using rivatuner for quite a while now :) so it's not like I was discovering the software or something ;)



Here is my problem :



I took the good .exe file (which is metro.exe located in the Metro Last Light Redux folder on steamapps/common)



I tried everything, low, medium, high level detection, custom d3d on or off,

there is nothing to do, the FPS counter doesn't show, and the framerate limit doesn't apply, is there a way to make it work somehow or it just doesn't work with that game in particular ?



Thank you for your time :)
