Guys I've achieved my solution after ripping the web. for windows 10 users, Try going to graphic settings from the display settings menu, you'll have the option to browse an app, add the Photoshop.exe from the installation folder , then click on the added selection and press -> options. Now choose -> High Performance, and Save, restart Photoshop.

Hope it'll work for you guys.
