I own Lenovo Z510 laptop with configuration - i5 4th gen, 6GB RAM, 8GB SSD(hybrid). and Nvidia GeForce 740M. Even in this configuration Illustrator and Photoshop CS5 is lagging (Even when working without textures, just plain colors). How can I optimize the settings? In Photoshop for hardware acceleration it uses onboard Intel 4000 graphics. Is that the reason? I am not getting Nvidia on drop down (switchable graphhics?).
Please help. Its painfully slow!
You definitely want Photoshop taking advantage of your video card (Nvidia) instead of your chipset (Intel). You like will have to configure you graphics settings so that the chip set is turned off to get things working correctly.
