| Dark_Feanor said: You didn´t have to repost your all explanation I´ve read and understood the point you are trying to make. But first thing first, AC-U is not the first 30 fps sub 1080p game, there is another that uses the same engine (or very similar) and it´s also an open world game (surely it´s also crossgen), but you understand. And also remember that AC4 needed a patch to reach 1080p. Remember the 9 women. And you might also be familiar with the "Phylosofers Lanch (or dinner?)" CPU and GPU have to share the same memory pool. The CPU has to have room to do the calculation, as @ethomaz said, they are not using GPGPU. If they have extra time to toiled the engine for the extra compute units to work without overloading the memory bus they could reach 1080p on both consoles, may be... But there is time to market, they have to ship the game right now the best way they can. PS: Good luck with your best app ever, hope you don´t expend too much time optimising for every platform... |
There is nothing wrong with a game being sub 1080p, and the fact that they needed to patch PS4 AC4 to reach 1080p pretty much tells you all you need to know about Ubisoft. I was just pointing out why the reason or excuse they gave is BS. As I said, there is a reason for why they did what they did. And I know what it is, its nothing bad per say... just that the reason they gave is not true.. and honestly insulting if you know anything about how games render pipelines work.
And them using GPGPU has nothing to do with this.
I also think some people don't realize how litle bandwidth or actual data any CPU tasks uses. To help put things in perspective? The CPU you are using to read this right now (assuming you are reading this on some sort of desktop/ laptop. Of Which its OS uses DDR3 ram. And I am going to assume its using amongst the fastest DDR3 ram out there. Has a peak memory bandwidth of under 20GB/s. More like 17.8GB/s to be exact (well depending on cpu it can be pretty high tho). Now do you think a game that will run on that that same PC, along with its memory hungry OS all within the confines of that 20GB/s, some how is bandwidth starved on consoles with 60GB+ and 190GB+ of memory???????
Oh, and thanks for the well wishes.. I hve only been working on that particular app on and off for the past 3 years lol. Becoming clear to me its not a one man job.
Fun fact:
Do you know you can completely saturate all the processing resources of a CPU and literally bring that CPU to its knees with code no bigger than 4kb?
