It's always a bit amusing seeing GPU reviews. You'd almost think that absolutely no titles in existence are optimized for NVidia GPU hardware and only AMD hardware receives any optimizations. I don't believe I heard the author of that video mentioning even once that NV might be performing better because a title might be optimized for NV hardware.
But man, if the AMD GPU had a significant lead, it's almost always because the title must have been optimized for AMD hardware.
Note: I'm not saying a game might not be more optimized for AMD hardware, but I think it's a bit naive at best to believe that no titles receive any optimizations for NV hardware.
I mean it should be obvious that both vendor's GPUs receive optimizations in games to a greater or lesser degree with NV hardware generally benefitting from more optimizations just due to NV spending more than AMD on devrel.
