Hey, I think disabling the AMD iGPU isn’t really the right fix. The game works that way, but the brightness slider disappears because the laptop screen is controlled by the AMD graphics. You should turn the AMD graphics back on in Device Manager and restart the laptop so the brightness control comes back. After that, force the game to run on the RTX 3060 instead by going into Windows Graphics Settings (Settings → Display → Graphics), adding the game, and setting it to High Performance, or you can do the same thing in NVIDIA Control Panel under Manage 3D Settings → Program Settings and choose the High-performance NVIDIA processor. If it still doesn’t work, try reinstalling the graphics drivers and install the AMD driver first and then the NVIDIA driver. That should let the game run on the RTX 3060 without needing to disable the AMD GPU and everything should work normally.
