Assassin's Creed II for PC Uses Only DX9 Features

by - source: Tom's Hardware US

Got a fancy new video card? Assassin's Creed II won't take notice -- but it's still a beautiful game.

Assassin's Creed II was one of the best games I played and one of the few that I finished in 2009. I couldn't hold out for a PC release, but those of you who are waiting until early March to play this superlative sequel will get a few perks.

David Champagne, 3D Lead Programmer of Assassin's Creed II, said in an interview with PC Games Hardware, "We spent quite some time improving the performances of the PC version by taking advantage of multi-core processors. The PC version also supports much higher resolutions than the console version and multi-sampling modes up to 8X (as opposed to the console version which only supports 2X)."

Assassin's Creed II will also take full advantage of quad core processors, especially for those who can process more than a single thread. "We now support up to 8 threads. Our engine being mainly task-based since AC1, it has been pretty easy to scale up and parallelize the various tasks all over the multiple threads." Champagne added. "Most of our game systems, including AI, physics, animation and rendering, are taking advantage of multi-threading. … Physics is a task as any other tasks in our engine. We don't reserve a specific thread to perform the physics calculations. We didn't have the chance to look into Nvidia's Physx."

Those of you expecting more whiz-bang effects over the console versions will be disappointed, however, as Assassin's Creed II is a DirectX 9 affair.

"We are using the same rendering engine as the Xbox 360 version which is based on DX9. Integrating DX11 in our renderer would have definitely been too much time-consuming given our release date," said Champagne. "Assassin's Creed II has no specific support for DX10 (but the game still runs smoothly on both DX10 and DX11 systems)."

While that piece of news is disappointing for gamers who have purchased a new ATI Radeon HD for DX11 hotness, Champagne cites a Steam survey that has 40 percent of gamers still using Windows XP.

So when will he feel the need to jump to the newer API? "Assassin's Creed II has no specific support for DX10 (but the game still runs smoothly on both DX10 and DX11 systems)," he answered.

lol im quite content with the available options... The game looks amazing on console, it's undoubtedly gonna look miles better on pc whether it supports DX11 or not.

Who cares, it's not like the console version was bad or anything.. besides they do have graphical features suitable for the PC.. well somewhat.

but not as good as a DX 11 setup. Its the pc being shunned again..

a ropey port of a ropey game..

I just think that pc games are owed more than that or we will be swapping to consoles.

YEa it does kinda suck.. but then again that's how the market works.. they'll go wherever its profitable..

However, as far as the game goes.. ur mistaken.. i have the game on PS3.. it is sensational... try it..

In play you wont see the difference. Be honest, its only when you actually stop and look for them, or compare screenshots that the differences are apparent. It's all just marketing hype.

Dx10 or DX11 does not mean good graphics. and DX9 does not mean "Bad" graphics. We've all seen some fantastic looking games that are DX9c while most of us are still waiting on the undeliverd promises of DX10 let alone 11.

I mean yeah its still a good game and are doing good imrovements, but come on ! :-)
Use a new renderer damnit..its useful for both versions. We pay you lots for your game damnit ! :)

why, the difference between dx 9 and dx 10 was so minimal that most wouldnt have noticed..

why do you think pc gaming started to fail when vista came out. dx 10 wasnt that much of an improvement compared to dx 11..
and vista was crap.

is it too late to save the pc gaming slide in to console ports and demising titles.. ... time will tell.

Rab1d-BDGR :
Agreed, If they're going to sell us 2005 technology, they ought to charge us as if it were a 2005 game. RRP at launch £5 or 3 for £10... They should publish through "Sold-Out Software".

differences are HUGE. Its just that many devs dont use DX10 thanks to crappy consoles.

Anyway they emulate some DX10 functions with DX9. Its not so good results and anyway is not so optimized, so they drain resources and have to cut more things.... just look Mass Effect 2, awesome game im in love with it, but it drain lots of resources of poor consoles with this technics as high res texture and so they had to do heavy cut in gameplay.................. ( anyway most console run really in 720p maximum NOT native........ ).

Look instead Crysis 1 on PC with full details, its HUGE the difference and Light Years away !

Come on now, yes consoles do pose problems for pc games, but that doesn't mean that they're "crappy" lol.

Of course some PC games are going to be based on the console versions. There's a million and one good conversions out there. That it's a port is not a problem - and it's a port that has been thoroughly optimised for multi-core and higher resolutions - sounds like they did a hell of a lot more work than Rock* with GTA-IV.

The other thing is that the developer has targetted it's work to the PCs gamers are actually using - you know, the facts people? Steam usage reports show that the majority of people use multi-core CPUs so loads of work has gone into them. The same reports show that there is still a very high percentage of people that don't have Dx10 / 11 capabilities, so the dev time didn't go into it.

They are only responding to the market that's out there.

@ kyzar

If all games were designed for the technology most people currently have, there would never be any need to upgrade.

For instance, why buy dx11 cards if there are only dx9 games. That theory would stagnate the hardware industry.

@devilxc

That's a valid point - it's a difficult time for game developers. The xbox is dx9 based, so there's commonality to engines that helps with development costs and time. While I agree that there should be dx10 / 11 enhancements offered, there is a danger of alienating a large proportion of the customer base if a title was made dx10 / 11 only for example.

In the case of ACII, there presumably was a limited budget for development of the PC version, they chose the PC technology that has been almost universally adopted (multi-core) and were able to offer enhancements over the console version that almost everyone can benefit from. Yes ideally they would have the budget to provide a dx10 / 11 codepath as well, but if there is only so much money / time I would say they chose the right enhancements purely because it affects the most people.

Dx11 seems to be slow taking off - maybe asking people to upgrade their gfx hardware so many times in the past couple of years given the world economic climate is a little shortsighted. My first gfx card (a Geforce2 GTS) lasted 4-5 years, it's replacement (a 5700 ultra) lasted 2 years, since then I've upgraded at the most every 9 months. It's a lot of money to keep dropping into my PC - especially as I have several gaming-capable machines. I know I won't be upgrading my GTX280 on my main PC for a while this time though. The dx9 performance is fine for my 1920x1200 screen and there's a bucketful of older games that I don't want to say goodbye to yet by upgrading to '7.

yeah totally agreed.

Kyzar, if a good porting i thanks for it, but usually even a good porting anyway dont change gameplay and design limitations.......

CJ consoles are crappy outdated toys compared to a PC, no way.
And are much more oriented for dumb and casual gameplay. They are ruining the game industry, but its my opinion. Yeah luckily there are exception, but how ?

I still think anyway the best choice at this time was made it by Crytek.
Will see.

lol Crappy outdated toys ? heck even PCs are "toys".. Consoles are not for "dumb" and/or "casual" gameplay.. they're actually pretty competitive and have more players on than PC does at any time. Consoles make more $$ than PC can ever dream of making, so you should think twice before insulting em. Maybe PC gamers are sorta jealous, that consoles get so many more great games. But i understand ur pain.. i'm a pc gamer too, but thankfully i have a console too, so u see i enjoy best of both worlds..

PS: PS3 owner. ;)

To somewhat an extent, perhaps, yes, but you we still enjoy benefits such as some games with new features such as DirectX 11, more AA options etc.
