Do you share the blame with the janitor at your workplace when he knocks over a vase?

So you agree that this is the fault of the person who hired the janitor and gave him not enough time to clean the rooms which is why he has to hurry and knocks over so many vases in the process.

CPU wouldn't affect Resolution in the slightest however. Even if the AI was so complicated which is I beleive is a load of crap, adding more detail per render pass would have nothing to do with the AI processes of the NPCs. CPU acts as a bottleneck for framerate when, it has to keep up with the GPU. Not to mention the XB1 and PS4 have nearly identical ARM CPU's, i.e mobile CPUs, and most of their processing power goes towards the OS and multitasking, both beefier on the One because of its heftier OS hence the 0.15 ghz clock speed increase. In other words, the CPU excuse doesn't hold much water.

It simply takes advantage of how little people actually know about what the clock speed difference actually means.

ubisoft should have reduced the number of NPCs by half at least to maintain the framerate stability if the CPu was holding it back. theres no need ot have 5000npcs on one screen.

I'm just repeating what Ubisoft said and my post is basically debunking what they said.

"We decided to lock them at the same specs to avoid all the debates and stuff," senior producer Vincent Pontbriand told VideoGamer.com while explaining that it's the consoles' CPUs – not the GPU – that prevents Ubisoft Montreal from improving the game's performance.

"Technically we're CPU-bound," he said. "The GPUs are really powerful, obviously the graphics look pretty good, but it's the CPU [that] has to process the AI, the number of NPCs we have on screen, all these systems running in parallel.

"We were quickly bottlenecked by that and it was a bit frustrating, because we thought that this was going to be a tenfold improvement over everything AI-wise, and we realised it was going to be pretty hard. It's not the number of polygons that affect the framerate. We could be running at 100fps if it was just graphics, but because of AI, we're still limited to 30 frames per second."

Here's some more bs from Ubisoft if you're interested.

"The PS4 couldn’t handle 1080p 30fps for our game, whatever people, or Sony and Microsoft say."

AC Unity optimization is garbage, we know that. But a Dinasty Warriors or Musou game isn't a good example. There isn't heavy AI there. The game just puts a massive amount of NPC on screen but only the few close to you are running AI routines, the rest is just idle and the game applies the exact same animation with some frames of difference. It isn't a demanding game, even the PS2 did it. It's just smoke and mirrors.

Just to add: the lack of CPU won't limit the resolution. The only CPU calculations would be AI, animation, whathever and that's just change things in the geometry stage of rendering. When you rasterize (basically, "convert" triangles to pixels), it's only GPU. A CPU bound game can limit the framerate, because the CPU may need more time to do a routine, but if you pump up the GPU you can pump up resolution. They could say:

"The game is 30 fps because of the CPUs"

But not:

"The game is 900p at 30fps because of the CPUs"

Again, I only listed that because that's how they explained their comment.  They were coming off the previous 900p parity comment straight into "the reason why we said that blah blah CPU blah blah."  I'm aware the CPU has nothing to do with resolution, I'm merely explaining for, what is it, two or three times now(?) that I even inferred resolution because their bullshit comment.  Even in what you quoted I stated the only reason for the reply was because of what Ubisoft stated.

I kinda don't think that people would complain less if the PS4 version was 1080p.

Imagine if Ubi never said anything about the CPU and the game ran on 1080p but with a shittier performance than X1. I could see people complaining that they should lower the resolution to improve performance^^

What REALLY debunked the parity excuse, is the fact that its simply a terribly optimized game and runs like shit on ALL platforms, even PC.
