I have NVIDIA Optimus technology in my laptop (switchable graphics). DayZ no longer runs on my laptop's dedicated GPU. I have a Toshiba laptop with a NVIDIA Geforce GT 540M. I never had an issue running DayZ in the past.

Upon launching DayZ the game runs only on the integrated Intel graphics in my laptop. It will not run on my dedicated GPU. All of my settings in the NVIDIA Control Panel are set to force DayZ to use the dedicated video card but DayZ does not trigger the switch in Optimus.

I have no issues with any other games that I play (including H1Z1, Team Fortress 2, Arma 3). Once I start them, they all utilize my GT 540M. This is a DayZ only issue, which only recently started to happen, and it's very disappointing since DayZ is my favorite game, but now it's completely unplayable.

Please help. :/
