Lets make it very simple

1. optimisation : it can make a huge diffrence interms of framerate, quality and resolution, a good example is PES 15. Fox engine isnt optimised for Xbox one resulting in a resolution of 720p compared to 1080p on PS4.

2.Computers are running much higher specs, here is what i mean

 Wii U  has 2gb of ram and 32mb of esram. it runs  arkham city (with very little optimisation ) at 720 30fps.  the computer which is running the game with 1080p probably has  atleast 4gb or ram and a core i3 processor which is 4 times more powerfull than that of ps4 and xbox one.

3. the game was intended for limmited number of systems and the Wii U version was just and xbox 360nwith diffrent UI.

4. even the game is not running well on its intended systems. here is quote from Wikipedia"

Technical issues

During launch week, issues were found to exist in the code-restricted content. Some customers discovered the code to be missing from their copy, preventing them from obtaining the Catwoman story missions. The problem was reported by customers in Canada, the United States, and the United Kingdom. Warner Bros. issued a statement claiming that the missing codes had affected less than 0.5% of customers.^[227] Upon release in the United Kingdom, a technical issue rendered the game unplayable for some players, booting them from the game with an error message that the "downloadable content is corrupt." Rocksteady European community manager Sarah Wellock claimed that the fault lay with the PlayStation Network and Xbox Live online systems.^[228]

In early November 2011, Rocksteady confirmed that it was investigating reports by numerous users that save files for the Xbox 360 version of the game were being erased without prompting, resulting in players losing their progress and being unable to complete the game.^[229][230] On launch, performance issues arose for the PC version when DirectX 11 features were enabled; the developer acknowledged the inconvenience and recommended to run the game with DirectX 9 while a title update was released to address this matter."

 

if you want more . Arkham city runs terribly on my PC which has an amd 9590 CPU and GTX 970.

PC games arent optimized, so the same game on a console with the same specs should outperform the PC game, and we see countless benchmarks that show the AMD HD5550 (320 SPU) running games much better than Wii U runs them.  Im not saying they were properly optimized for Wii U, but a 320 spu gpu should be running them better.  Even if your cpu limited, you should still be able to up the resolution, that doesnt add any work to the cpu, just the gpu.  I think the 160 spu gpu makes more sense, and would easily outperform the AMD HD6450 GPU in a console setting.  What is curious though, the X1 seems to be underperforming.  I find it hard to believe that a 1.2 T-flop gpu struggled to run COD Ghost in 1080p when weaker GPU's on PC handle it just fine.  When you look at X1's specs, it seems like its underperforming for sure.

Sorry, but no.  Pointing to the good looking Nintendo first party games only prove Nintendo has talented artist and programmers.  The HD5550 can run Batman Arkham City in 1080p native, and hold a framerate well above 30 fps.  Wii U struggled to run it at 30fps in 720p native.  I dont argue that these ports werent properly optimized for Wii U, but PC games arent optimized either.  A PC with the same specs as a console should never outclass it.  Ignoring game performance, some pretty educated people wete able to actually count the registers, and there were only enough for 160 spu's.  So the two scenarios we have is that either Wii U's GPU is a close match to the HD6450, even power draw supports this, or its close to the HD5550 but for some reason severely underperforms.  The HD5550 can run ever single multi plat far better on PC than the Wii U runs them.  It would actually support the idea of incompetance if Nintendo built a console that is less than the sum of its parts.  

AMEN!!! The Wii U is fine for what it is...Nintendo games in full HD resolution!!! Let the fools still thing that the Wii U has "only 160 SPU"  and has less GFLOPS than the X360. The trolls will never see how good of a system it really is.  I for one have been enjoying Mario 3D World, MK8, W101, Pikmin 3, ZombieU (yes ZombieU), Child of Light, Rayman Legends, Trine 2 etc.  I am looking forward to picking up Bayo 2 , Hyrule Warriors, Smash, and Captain Toad.

Im not sure if your saying its not that big of a deal, or trying to say that the Wii U doesnt have a 160 SPU GPU?  Its been pretty well proven that the 160 SPU theory is more than likely accurate.  All you need to do is look at the AMD HD6450, a 160spu GPU with 8 texture units and 4 rops (Wii U's GPU supposedly has 8 ROPS), but overall is very close to the Wii U's suggested specs, and as you can see from testing done, it can outclass the 360/PS3, and thats in the PC environment.  Take a look at this if your skeptical.

People, and I am no exception got to hung up on the "flops" performance of the GPU.  The majority of developers gave positive reaction to the GPU and memory, it was the CPU that gave them some fits.  Time constraints and cruddy dev kits and support from Nintendo is what caused the underwhelming performance with the early ports, and then the low sales of Wii U resulted in publishers devoting very little resources to the Wii U ports.  Imagine if all the early ports had been as good as Need For Speed MW and Bayonetta, the perception of Wii U might be a bit different throughout the industry.

I can always appreciate developers who speak freely.  The truth is there is very little business incentive for publishers to invest lots of money to rework the game engines for Wii U, and Wii U wont be included in next gen engine development for two reasons, one being sales of previous games released, and the second being the power chasm between Wii U and X1/PS4.  The power chasm itself woudnt be a deal breaker if software sales were great on the platform, but Ubisoft isnt going to invest a bunch of money into their AC engine for sales of 150-250k, same goes with Activision with COD.  Exclusives wont be held hostage by a lack of power on Wii U.  Mario 3D World looks great, Pikmin 3 looks great, DKC TF looks really nice, and if the Zelda HD demo is any indiciation, the next Zelda is going to be very pleasing to the eyes as well. 

The idea that the extra power of the X1 and PS4 is revolutionizing games is crazy, there is nothing on those consoles that couldnt be done on Wii U with some visual compromises. 

Its a good read, but most of it we all concluded anyway.  You mean to tell me that highly optimized code for the 360 cpu did work very well on the Wii U cpu, two processors worlds apart in design and architecture?  Im shocked, who would have thought. LOL  The stuff about Nintendo's tools sucking and being slow with info is no surprise.  Nintendo has a bad track record with sketchy info and tools.  

With all these critics that use the lack luster ports as proof that the Wii U is a total dog, most of them believing that its actually less capable than the PS3 and 360, I would say to them, do you honestly believe if Bayonetta 2 were to be ported to the 360 and PS3 by an outsourced developer with a limited amount of time that the results would be great?  Anytime you have some serious fundamental differences, and software that is optimized for the strengths of one piece of hardware while avoiding the weaknesses, that may not transition very well to another piece of hardware, even if that hardware a bit more capable overall.  Imagine if the a game were developed for Wii U that really leaned heavily on the edram.  Im talking serious optimization to make the most of it.  The games fundamental foundation is built around it.  Now try and port that game to the PS3 and 360 in 6 months and let me know how it goes.  Would that make the Wii U significantly more powerful than the 360 and PS3?  No, of course not, but it goes the other way as well.  There are some serious fundamental differences, and its hard to leverage software designed around the strengths of another console. 

The edram is currenty estimated to be either 35 GB/s or 70GB/s.  Im guessing 70GB/s because that would be in line with how they are using it.  Its enough for the frame buffer/z-buffer to never saturate bandwidth requirements, making bandwidth a non issue for the gpu.  This allows the main memory to act as a read only memory for the most part, meaning the 12.8GB/s to the DDR3 can be used for textures and assetts without sharing bandwidth with Z-buffer calls.  Whatever the real numbers are, it does not appear that the gpu is bandwidth starved.

The jump made last gen was insane.  Not only in outright power, but the addition of programable shaders brought graphics to a whole new level.  Just adding more and better shaders doesnt deliver the same kind of leap.  Wii U is a good design, and developers that really try will find ways to optimize their code for the hardware over time.  PS3 and 360 have had over six years of optimization.  Wii U may not see an enourmous progression over its lifetime, but its foolish to think its maxed out already.    

The numbers can make it sound worse than it is.  PS4 and X1 may be 6-8 times more powerful than Wii U, but the 360 was about 20 times more powerful than the xbox, and the PS3 was about 30 times more powerful than the PS2.  The cycle didnt repeat, the X1 and PS4 are not near as cutting edge on launch day as their predecessors were.

Hope VGchartz is correct because that would mean 750k sold after the first three weeks.  We really might see Wii U sell a million for the month of December.  That would be incredible.

I am guessinig 750k worls wide for Wii U in December.  A solid number, but still needs to improve to stay relevant for years to come.

Yes i am looking forward to 2014. nintendo is claiming they have 3rd party content coming from the big publishers... I am calling BS. they are probably talking about lego games, and the next skylanders and disney infinity type games. Nintendo needs to stop the BS not one really big game for 2014(outside of watchdogs which will probably be sucky 360 port) has been announced for Wii U. it isnt a big deal for me because i can play through about 5 good games a year and be fine... so MK8, X, Smash 4, Bayo 2, and DKTF and i am good... but for those that want 3rd party support you are Fu(%ed.

Somebody had to say it.  Third party support is going to get rainbowty.  Pathetic software sales of this years ports doom any chance of better third party support next year.  Wii U is an exclusive console 100%.

Wii U is on pace to sell Dreamcast numbers.  Nintendo should be more worried than their fans.  We still get Mario Kart, Smash Bros, X, Bayonetta 2 , and Zelda regardless if the Wii U sells ten million units or fifty million units.  

The smaller screen gives really good pixel density, so even though its actually lower res, the pixel density is higher.  Most games look as good or better on the Gamepad as they do on my 42in LG LCD 1080p tv.  Rayman Legends was the standout on my tv, it being 1080p native allowed it to look cleaner on my TV, but games that render in 720p are likely to look as good if not better on the Gamepad. 

At least we finnally know for sure.  It truly is just a Tri core Broadway shrunk and over clocked with more cache.  Basically little more than ten times the power of the Gekko that powered the Gamecube, or six times the power of the Broadway that powered the Wii.  Should be just fine for most games.

Unless your looking to play one of the less popular modes, it should be easy to get into a match.  TDM is the most popular by far, but Domination and Free for All usually have quite a few people playing as well.  Trust me, after Christmas, the amount of people online will triple, possibly even more.  Some of the more obscure modes will always be a little light on players, but the majority of modes should be easy to find full matches after Christmas.

Anybody who buys COD every year knows the first two months are beta edition.  LOL  Its said but true, the games come unfinished every year.  Its just the way of things these days.  Patches are great, but it means developers can get away with shipping less polished software are launch.  A_Trey_U is saying we should see a noticeable improvement with this upcoming patch. 

Ok.  I was just responding to the absurd "rumor" that PS4/Xbox One are 720p and Wii U is 1080.  And yes, quite interesting that PS4 is not 60fps.  

Its 60FPS, but not locked like your would expect.  I am hearing that it can drop pretty low at times.  It moves around on Wii U as well, but Treyarch has already said they have some good optimizations in the works that should smooth things out. 

PS4 has been confirmed native 1080p

Its also been confirmed that it has performance issues.  Honestly its pretty suprising that the PS4, the most straight forward hardware design in consoles history has any troubles at running Ghost in 1080p 60fps, but apparently the framerate is all over the place.  Wii U is far from locked 60fps as well, but PS4 was supposed to be the monster that would have no issue with 1080p 60fps, and so far its not quite as easy to achieve as people had hoped.  Rich at ReviewtechUSA made mention that the Wii U version of Ghost performs quite a bit better than Ghost on PS3, still waiting for a comparison of the 360 version.  Treyarch has faithfully brough Ghost to Wii U, and are still working on further optimizations to make it better.  

Ghost is not a visual masterpiece, but dont let the haters fool you, its not a bad looking game either.  Yes there are some low res textures, but the scope of this COD is quite a bit larger than COD has been in the past.  I think in some ways IW bit off more than they could chew and some compromises were made, but overall I really feel like the changes they made were all for the better. 

I do intend on buying it online for £38 in the next few days.
How many players has everyone seen online now?

So far about 1600 in the evenings.  It will go way up after Christmas.  COD on Wii was averaging 7500 to 30,000 back in the day with Black Ops and MW3, so hopefully the COD Wii U community continues to grow. 

Well I hope you consider getting Ghost down the road.  We are really enjoying the online multiplayer.
