Acer Predator PH315-53 nvidia optimus switch doesnt exist
i have a problem while gaming using internal screen with low fps and laggy experience and i have i7, rtx 3070… when connected to external monitor everything works fine. no mux switch exists in bios or in nvidia optimus in nvidia control panel. i checked my laptop specifications and it says it should have nvidia optimus. for the past month this has been a big pain in the a** since im traveling a lot and i bought this laptop for gaming while travelling. big dissapointment since i payed for this lap little over 1600 euros.

No setting need. When you connect your laptop to an external monitor, the monitor will typically use the dedicated GPU (dGPU) because the HDMI port is directly connected to it. To disable the integrated GPU (iGPU) for a performance gain, go to display settings and set the screen to be shown only on external monitor, which will be your external monitor.
And Nvidia Optimus is a hybrid graphics system that automatically switches between the integrated GPU (iGPU) and the dedicated GPU (dGPU) depending on the graphical load. With Nvidia Optimus, the iGPU typically remains active to handle display output, as the laptop display is directly connected to it. This is the case even when the dGPU is rendering frames, unless a MUX switch is present.

So is there a way to use laptops screen and use only dgpu or igpu will always be used unless u connect external monitor. There is huge diference between fps while gaming and i just cant wrap my head around it. As i can understand it dgpu and igpu are used in some simbiose and there is no way to cut out igpu when using laptops lcd.
