For me it´s working fine, but I canc it and went back to Wind 7.
Under Win10 I can´t make my brightness higher. It´s quit dark if I played AA on Win10.
Should be same way than in win8 to change brightness. Assist video settings - win8 gamma. Then set that gamma to what you would use in map you play most often. In game you can alt tab to desktop, find gamma control in programs next to clock, right click and settings. Then adjust it, and get back to game. That works for me.
Be aware win7 users that free win10 update ends soon, and after just some years win7 will become like winxp - unsupported. I think part of its support has already ended, it only gets security updates.
