Added a comment to my ongoing driver thread, but thought I'd put a separate post for this particular issue. AMD just released their annual graphics driver/feature set improvements. Unlike the rest of the drivers which just bork sleep, the latest version pretty much made the laptop useless. Not sure what the improvements were, since the screen was almost too dark to do anything useful. Had to uninstall and roll back driver. If anyone has any better luck, let us know.
To Acer, I don't know what makes YOUR Vega 56 so much different from every other Vega (other than the drivers work on those), but it would be REALLY nice if you got to the bottom of it and fixed this. An expensive, high end, gaming laptop stuck on launch day drivers is a complete joke. Please don't make me regret my first purchase of an Acer product.
