Im Currently running an asus xg27vq it says whenever I check that my monitor is running in 144hz, I have an i7 5930k not oc and a r9 290 4gb of ggdr5. So now when I goto boot Rise of the Tombraider and go into setting i'll enable exclusive fullscreen (So i can change refresh rates) and set the game to 144hz, after I close the settings tab and re open it, my refresh rate will be set back to 60hz but other settings will be saved. Thanks in Advance for any help :)
