So, I have a 4K TV and an ASUS TUF Gaming A15 laptop, when I plug the HDMI into my laptop to connect it to my TV so I can play some controller-based games on the couch, I see that Desktop Window Manager seems to absolutely destroy my FPS. My Nvidia GPU will be at 30% (GPU the game uses.) While my AMD iGPU will be at 60% or even higher... All just from Desktop Window Manager. Is there a way to make it not eat away at the FPS so much, or... Maybe even swap Desktop Window Manager to use the Nvidia GPU entirely? Asus support was no help.
I already tried going to Graphics Settings and setting both the game and Desktop Window Manager to the High Performance (Nvidia) GPU, but DWM keeps using GPU-1 (AMD iGPU), even after a reboot. Please help!
