So basically my Laptop performs much better when gaming through an external monitor plugged into the HDMI port. When an HDMI monitor is plugged in the built-in Intel GPU disables itself and I get much higher fps in-game. Like 30-40fps better, its a huge difference. I am plugging into decent monitor and running the same resolution as the built in monitor. Ive used SmartUpdate to flash bios/update all. Everything is up to date and Ive even reinstalled win10 recently. If i go into device manager and disable the intel gpu it runs even worse. Would appreciate some help or suggestions.
