I bought a laptop a few months ago with Advanced Nvidia Optimus technology (MUX switch) and it's been a rollercoaster of VGA related issues ever since.
My laptop has two issues (well, more, but those two are deal breaking):
1. Laptop has micro-freezes (0.5-3 seconds long) when using certain UI elements, eg. wifi/speaker/battery button, right clicking on desktop, locking the account, turning off laptop, using browser, maximizing minimized apps.
2. Laptop stutters every 10-20 seconds when it's unplugged from power. It happens either on AMD or NVIDIA GPU, but never on both during same session.
I have noticed that if I turn off Hybrid Mode (MUX switch on), I don't have this problem, but I also lose ability to use the lovely AMD GPU that is great for older games.
I have also noticed that UI stuttering does not appear for as long as I don't install AMD drivers.
I have tried both Lenovo certified drivers as well as official drivers from AMD and NVIDIA site, turning off AMD PSP, reinstalling drivers with/without DDU, changing power plans, nothing works. The laptop will just stutter with MUX off/Hybrid Mode on.
After reading different threads for different laptops I think that both issues are caused by Advanced NVIDIA Optimus technology.
Is there a way to make this thing work? My old laptop had older Optimus technology and it worked great. This one is the newer and pricier laptop and it has worse stuttering than the old one lol. It drives me crazy but neither Lenovo nor NVIDIA knows what to do... They just tell me to turn off Hybrid Mode/iGPU.
UI micro freezes on AMD look like this:
Constant stuttering on battery on AMD/NVIDIA is like this:
Please somebody help me. I want to be an AMD user but everyone tells me to just turn it off instead of helping fix it.
