Why the graphics on my Y70 Touch do not perform well when I run Solid Works engineering program? I run it ok before. my graphic card is NVIDIA Ge Force GTX 860M. The laptop run on Windows 10 updated to the latest version.
I don’t know much about that machine, but maybe it’s not switching from the intel GPU to the Nvidia? You could check with Nvidia’s page for a driver update.
