Look you can say what ever you want, but half the things you mentioned are in GTA 4 at a much higher quality. You can see it in the video as clear as night, and day. The shadows, physics, streaming, and stability are all grossly superior in GTA 4.
Those are all isolated examples, and some of them were due to bugs. That comparison video was done right at the time of Watch Dogs launch, so some of those issues have been patched out. Also, Watch Dogs doesn't focus on driving the way that GTA does so some of it is also due to developer decisions..
Like I said, there are numerous flaws and faults with Watch Dogs, but don't for one second think that those flaws diminish the overall technical quality of the game. Watch Dogs does have lots of technical qualities not found in the GTA series.
Game development often requires compromises because of hardware and software limitations. If Watch Dogs had not released on last gen hardware, then they could have pushed the engine more.. I suspect Watch Dogs 2, which will be next gen only will rectify all of the issues found in Watch Dogs..
The other things you mentioned are irrelevant as those technologies didn't even exist back when GTA 4 first came out we are comparing what they can both do at the same time. Now if you want to compare it to GTA 5 on PS3 to the PC version of Watch Dogs than you will see just how embarrassing it is for Ubisoft with a contemporary equivalent. Even with last generation tech GTA 5 still smokes Watch Dogs in everything except resolution.
I don't think you even watched your video, which is somewhat biased.. You seem to think that Watch Dogs is a GTA clone, but it isn't. Watch Dogs is much more story driven than GTA, and the focus is completely different. Watch Dogs also has game mechanics that GTA doesn't have, like hacking and spying..
Also you are seriously doubting that CD project red are vastly superior game makers? The guys that have a reputation for technical excellence in all their products versus the dumb asses who botched their last three major releases on all platforms, and mangled the PC ports as well. The same jokers that make games that have shit like this happening in them.
CDPR are exceptional developers and I said that I had faith in them. But you're downplaying Ubisoft way too much for me to take your comments seriously. Ubisoft is the second biggest game developer in the World, and they didn't get to that position via incompetence.
Take AC Unity for instance. This game is technically
AMAZING. Never before has a City been rendered in real time in such detail and intricacy. The crowd generation is also unparalleled, with support for
THOUSANDS of NPCs. The landmarks of Paris like the Notre Dame Cathedral have also been created with 1:1 scaling..
I'll let this video do the rest of the talking:
