Forums - Gaming - Sniper Elite Dev Explains Xbox One 1080p Difficulties

blessedswine on 10 February 2014

theres one thing i didnt see said im sure as MS brings new development kits that make it easier so will sony thus keeping them just that much easier, same goes for performance as the generation goes on youll see more performance squeezed out of both systems, the PS4 will most likely stay the more powerfull machine as its not trying to be the Jack of all trades master of none.

Xbox One has a weaker GPU and slower RAM. This entire generation PS4 will have graphically superior ports.

That being said the X1 is more than capable of producing beautiful games.

I think this statement has inspired me to make a thread about this whole issue. Thanks a bunch.

Well it only has 16 ROPs ...


Meaningless statement. A 680gtx has less ROP's than a 580gtx, yet it's a third more powerful.

What a meaningless response ...

Yet you forget that the GTX 680 has a higher core clock therefore the ROPS on the 680 operate at a higher clock speed. Most graphics cards that aim at a 1080p resolution usually comes with 32 ROPS and more.

You quoted one spec, which is meaningless. A gpu's performance is based on all of its specs and overall design. Individual specs may be higher and may be lower at the same time.

Fine ... The xbox one has a lower pixel fillrate. Better ?

If this is true, resolutiongate was fun while it lasted.

It's FUD,a  new SDK doers not over come a 40-50% GPU compute advantage. He also acts like ps4 does not do media, the only diff between the two is hdmi-in port.

 

Ps4 tools will also improve as will OS overhead.

Gee golly I don't know who to believe, an actual developer working on the machines, or you.

Can I see some of the games you have developed? I have played many of the games this guy's studio has worked on. Just for a frame of reference, I mean. You seem so sure you know more about this stuff than someone actually working on the consoles is all.

Numerous developers have said the opposite...but you believe this one how convenient..

 

The power gap is there period,. it's technology not fairy dust, a SDK is not going to make a GPU 40% more powerfull. The proof is already there we know the specs of each box.

Xbox One SDK powered by Fairy dust i like it lol.

Hummmmmm...

GTX 580: 48 ROPs @ 772MHz
GTX 680: 32 ROPs @ 1006MHz *1058MHz boost*

We are talking here about 32 vs 48 with a big increase in clock for the 32... in any case the 48 is less than 5% faster than the 32... overkill for 1080p in both cases.

Now 16 vs 32 with the first running with 53Mhz more clock... seems like the 16 is really a bottleneck if you ask me for 1080p games.

Instead of seeking to convince others, we can be open to changing our own minds, and seek out information that contradicts our own steadfast point of view. Maybe it’ll turn out that those who disagree with you actually have a solid grasp of the facts. There’s a slight possibility that, after all, you’re the one who’s wrong.

Firstly: It is cool to use words like ROP and TMU and other buzz words, unfortunately you don't seem to know what they mean. As in real life, it is the weakest link that butes you in the ass in the end.

A 680gtx has 32 ROPs (at over 1GHz). This is more than enough to rasterize everything at 1080p/60Hz. Now the question is how many ROPs at what frequency you need to comfortably live at 1080p/60Hz (AMD recommends 32ROPs, by the way). Here is the sad truth for you: 16ROPs just don't cut it. This is the very reason why MS upped the clock frequency in the gpu instead of putting more CU's into their APU (as they discussed this decision without really telling why they went that way when the clock uptick was announced with great fanfare). The XBox One apu has enough compute power, but not enough raster power for a convenient 1080P/60Hz. (yeah, yeah, I hear people screaming "Forza 5! Forza 5!", neglecting to mention just how many clearly visible compromises that game had to implement to get to that goal. And just for the future: Every future game that goes 1080p/60Hz will show the same effect).

Secondly: The new developer kit is much faster. Cool, but it doesn't  run your game faster (unless the former compiler was shit). A faster SDK means that the compiler/assembler is now compiling the code much faster, like a minute instead of three, the linker is now taking only five minutes instead of fifteen to link the whole code bits into an executable. This is very nice for all developers but has no consequence on the fact: There are not enough ROPs for a convenient 1080p/60Hz.
