Hey we screwed over a large amount of our player base but let's brag about the HUGE numbers we put up. This is exactly why they hid the console footage. It wouldn't have put up these numbers if people knew what they were getting into
I think you overestimate the sophisitication of the average consumer. I'd be shocked if more than 10% of total sales were returned/refunded. And even that's probably still way too high a number.
In reality, while performance is bad on consoles, the gamebreaking stuff is probably affecting less people than you think, and most PC players seem pretty happy.
I'm enjoying it myself, even on my potato PC (2550k/970). The 'lushness of the open world' was the aspect I was probably least excited about, so them having overpromised in that area hasn't fazed me much. I've encountered a couple amusing visual glitches, such as a cell phone suspended in midair next to a character with an empty hand up to his head (why do they even need cell phones in this universe?), but nothing worse than that and nothing game breaking. Just some rough chugging frames while driving at high speed.
The story is good, the controls (aside from driving) are good, the graphics are good considering my PC, and the shooter mechanics are solid. Loving the atmosphere. Doesn't surprise me that it sold gangbusters despite the controversy, given the prelaunch hype.
