Great review! I love this game, so it's good to see it gets the praise what it deserves!

I've played QB in 1080p with mostly medium and high settings on an RX470 and it ran pretty well around 60fps with some minor setbacks to 45-50. I think it's a good idea to lower Shadow Resolution for example and a few other settings because you won't even see the difference in quality while the performance will be far better. But yeah, sadly it isn't well optimized overall. I didn't have buffering problems with the live action either and I have only a 30Mbps Wi-fi.

I have the Steam version though, it was incredibly cheap from Humble Bundle (12$ and it came with games like "The Long Dark", Dawn of War 3, Tomb Raider (2013), Sleeping Dogs: DE etc... ridiculous value), so if you have the Windows Store version, that can be the reason for this.

I wanted to see everything the game can offer, so I went for the 100% achievements and read everything, that was ~16 hours (you can replay the important parts, you don't have to replay the whole game). From an action game with a good story that is perfectly fine. As you said reading everything is an important part of the game, it just makes it a better experience.

"I hate Rockstar" - I've missed this somehow. :D Where is it?
