Hello Wonderland.
Thank you for your answer.
I installed the driver. It's working well !
I was just surprised because I didn't get warning message about unsigned driver, contrary to the video. I'm on win7 64bit.
EDIT : spoke so quickly... Worked at a moment and now, it's the contrary.
I don't understand, the values changed in regedit but didn't affect the game. I modified the sensibility on the game and since, no acceleration. I saved several configurations on povomouse but no one is considered. I'm going to try a reboot.
2nd EDIT : I'm trying to delete the driver. I'm following the steps but the console refuse to delete the package : pvh. I'm going to reset the computer... I think I have to reinstall each time the driver...
