Hey there, I’m going to start with – I dont know.
- What model of Asus do you have?
- Can you provide an output of your hardware types?
- Have you searched the various compatibility matrices that are available around the internet for your device to see how well linux supports it? <-- this one is important as there is more to support in a laptop than the graphics. Things like fn keys, keyboard and screen backlight, thermal management, etc.
For example, my Asus GL504G needs a few tweaks from the default install for the FN keys to work – and I need to follow the guides to get my hybrid graphics working properly – but it works, and works very well and while I have never sat there and measured FPS difference from when i switched from the default included Windows 10, gaming is still a nice experience.
As a side note, what you describe seems like such a horrible electrical design it baffles me that somebody would actually design that. To think that you design your system power requirements to be beyond what your main power rail can handle… !?! So, out of my own curiosity, I’d love to know your system model number so I can educate myself as to why this would be.
Lastly, I am no expert in this area, but v-sync would limit the graphics card’s output FPS to the maximum of your display (60hz, 144hz, etc) — so this would not increase your power usage, it could actually decrease it. (Here’s an old article on vSync, Double and Triple buffering and how they work: https:// www.anandtech. com/show/2794 Remove spaces in url)
