    Question Nvidia Optimus bottleneck bigger than it should be (ASUS Zephyrus M16)

    I just bought myself a Zephyrus M16 with a 11800H and 3070 (100W). Great laptop so far. I knew it didn't have a MUX switch but I use an external screen most of the time so it isn't really an issue. Having said that, I was still surprised to see some results while using the built-in display and...

    Nvidia Optimus

    I'm planning on buying the ASUS ROG Zephyrus 15 or the Scar 15 or something along those lines with the 5000 AMD cpu and 3000 Nvidia graphics. From what I understand these use Optimus and there is no manual switch to override the Integrated Graphics. I'm going to use it for AutoCAD and 3Ds Max...

    I just bought this model: Gigabyte Aero 15-X9-7FR4410P, and I can't set the refresh rate on the Generic PnP Monitor, nor can I make Windows understand that I don't want the laptop screen to use the Intel graphics card.

    Acer Predator x 34 or Asus pg348q ?

    Which one? Personally I like the looks of Asus better. Panels are the same. Any hints or should I wait for something new? I was thinking about 4k but you need too much of horsepower to run games smooth ( Titan x or 1080 sli) which in my opinion is now overpriced to enjoy 4k. So Asus or Acer?
