1.00 vs. 1.02 - Does it Matter?
If you read the previous pages, you can probably already guess the answer to this question. The 1.02 patch fixes a few minor errors, and it also removes DirectX 10.1 support. ATI HD 3000 series hardware is the only current graphics solution that supports DX10.1, so barring other changes there shouldn't be a performance difference on NVIDIA hardware. We tested at three settings for this particular scenario: Medium Quality, High Quality, and High Quality with 4xAA.
NVIDIA performance is more or less identical between the two game versions, but we see quite a few changes on the ATI side of things. It's interesting that overall performance appears to improve slightly on ATI hardware with the updated version of the game, outside of anti-aliasing performance.
This is where the waters get a little murky. Why exactly would Ubisoft removes DirectX 10.1 support? There seems to be an implication that it didn't work properly on certain hardware -- presumably lower-end ATI hardware -- but that looks like a pretty weak reason to totally remove the feature. After all, as far as we can tell it only affects anti-aliasing performance, and it's extremely doubtful that anyone with lower-end hardware would be enabling anti-aliasing in the first place. We did notice a few rendering anomalies with version 1.0, but there wasn't anything that should have warranted the complete removal of DirectX 10.1 support. Look at the following image gallery to see a few of the "problems" that cropped up.
In one case, there's an edge that doesn't get anti-aliased on any hardware except ATI HD 3000 with version 1.00 of the game. There may be other edges that also fall into this category, but if so we didn't spot them. The other issue is that periodically ATI hardware experiences a glitch where the "bloom/glare" effect goes crazy. This is clearly a rendering error, but it's not something you encounter regularly in the game. In fact, this error only seems to occur after you first load the game and before you lock onto any targets or use Altaïr's special "eagle vision" -- or one of any number of other graphical effects. In our experience, once any of these other effects have occurred you will no longer see this "glaring" error. In fact, I finished playing AC and never noticed this error; I only discovered it during my benchmarking sessions.
So why did Ubisoft remove DirectX 10.1 support? The official statement reads as follows: "The performance gains seen by players who are currently playing AC with a DX10.1 graphics card are in large part due to the fact that our implementation removes a render pass during post-effect which is costly." An additional render pass is certainly a costly function; what the above statement doesn't clearly state is that DirectX 10.1 allows one fewer rendering pass when running anti-aliasing, and this is a good thing. We contacted AMD/ATI, NVIDIA, and Ubisoft to see if we could get some more clarification on what's going on. Not surprisingly, ATI was the only company willing to talk with us, and even they wouldn't come right out and say exactly what occurred.
Reading between the lines, it seems clear that NVIDIA and Ubisoft reached some sort of agreement where DirectX 10.1 support was pulled with the patch. ATI obviously can't come out and rip on Ubisoft for this decision, because they need to maintain their business relationship. We on the other hand have no such qualms. Money might not have changed hands directly, but as part of NVIDIA's "The Way It's Meant to Be Played" program, it's a safe bet that NVIDIA wasn't happy about seeing DirectX 10.1 support in the game -- particularly when that support caused ATI's hardware to significantly outperform NVIDIA's hardware in certain situations.
Last October at NVIDIA's Editors Day, we had the "opportunity" to hear from several gaming industry professionals about how unimportant DirectX 10.1 was, and how most companies weren't even considering supporting it. Amazingly, even Microsoft was willing to go on stage and state that DirectX 10.1 was only a minor update and not something to worry about. NVIDIA clearly has reasons for supporting that stance, as their current hardware -- and supposedly even their upcoming hardware -- will continue to support only the DirectX 10.0 feature set.
NVIDIA is within their rights to make such a decision, and software developers are likewise entitled to decide whether or not they want to support DirectX 10.1. What we don't like is when other factors stand in the way of using technology, and that seems to be the case here. Ubisoft needs to show that they are not being pressured into removing DX 10.1 support by NVIDIA, and frankly the only way they can do that is to put the support backing in a future patch. It was there once, and it worked well as far as we could determine; bring it back (and let us anti-alias higher resolutions).

AC was only an average game overall. Graphics presentation was it's strong suit but gameplay was lacking and the game seemed to drag on as the player progresses through the game. Undoubtedly the repetitiveness was the worst part of AC. Not simply the fact that is seemed like some tasks were a redue of previously accomplished tasks but the shear fact that tasks were repeated verbatim with same characters and voices, only changing dialogue to create variation. Some characters players will have to kill multiple times under the guise of actually killing different characters in the game. AC was also disappointing in the fact that it mislead gamers in presenting its self a a somewhat stealth game. Nothing could be further from the truth. In AC players will often be forced into full on combat with multiple opponents to progress in the storyline. In vary select situations players have the choice of using stealth as a viable option. Ironically the last 5 or 10 minutes at the very end of the game are the most compelling. After the credits roll players are left in the main room to explore and decrypt code and hidden messages. It's unfortunate AC's developers couldn't have spent more time on puzzles that actually pertained to gameplay. Out of a possible 10 I give Assassin's Creed a 6.0 barely coming in at par, bordering on subpar.Donkey2008 - Monday, June 2, 2008 - link
It does have a Thief feel but after playing it on Xbox, I found it to be more Thief meets BloodRayne meets Splinter Cell with some of the best graphics I have seen in a while. It is sorta repetitive,but the violence cut away any boredom I had. I enjoyed it a lot.But I guess they could have done what other Rockin high-profile companies do and make an even more repetitive game exactly like its previous versions, but with a much worse soundtrack. Throw in some terribly low-res character models and reuse the same, bottom-of-the-barrel, cartoon-looking cutscenes and they would have a perfect 10 as well.

this is the kind of game reviews i'd like to see, wherein hardware is tested w/ a game to show performance. I mean, you guys ARE a hardware site and there are'nt many sites that do game reviews w/ hardware testing shortly after. I dont think u should do game reviews without hardware testing cause there are a ton of game review sites, but your niche shines when you do these hardware and DX analysis. cheers and thanks for a very informative article.DesertCat - Monday, June 2, 2008 - link
The article talks about wanting to check the performance of Assassin's Creed on a Phenom processor (and its 4 cores). I can speak to that to some degree.I have a Phenom 9600 (2.3 MHz) on an AM2 board (Asus M2N-SLI Deluxe) with an EVGA 8800GT OC (650 MHz). I play at 1280x1024 so I play in a letterbox mode. This processor is enough to run the game at acceptable frame rates but I would tend to think that a fast dual core would do just as well (like was found with the Intel processors in the article).
With the performance hurting TLB patch enabled, I noticed one area where frame rates truly took a nosedive: when doing the "look" pan from the top of one of those towers. I didn't have an fps counter on at the time, but I'm guessing it was in the 12-16 fps range based on the chunkiness I experienced. I got similar slow framerates when diving from those spots into the hay (especially the really high towers).
With the TLB patch disabled on my Phenom, those two low fps spots were much better. I'm guessing that those areas were in the low 20's of fps. The rest of the game was smooth as silk and probably above 40 fps. I do not, however, see high utilization on any particular core when I've checked.
If I was to point to areas that really stress a system in AC, I would say that the tower pan shots are the most common. (*minor spoiler ahead*) King Richard's speech from horseback about 3/4 the way through the game is also very intensive.

The word you *are* looking for is possibly letterboxing?PrinceGaz - Monday, June 2, 2008 - link
I was going to mention that as well. Anamorphic means the pixels making up the image are stretched either horizontally (as with wide-screen DVDs) or vertically when displayed. If the game were anamorphic, it would be like it running on a monitor at 1920x1080 but being rendered internally at some other resolution such as 1440x1080 and stretched to the displayed 1920x1080.The correct description is what you said originally, that it allows only a 16:9 aspect-ratio view, so if I ran it on my monitor (1600x1200 native) the game itself would only use the central 1600x900 of that.

Sorry - I saw the original comment and thought I corrected it. Missed the other two occurrences. I wasn't thinking and just used the word after reading the thread on widescreengamingforum.com about AC. (I was hoping someone had found a way around the locked letterbox view.)AnnihilatorX - Monday, June 2, 2008 - link
This review is great! I have never read a game review that includes all the analysis, benchmarks, gameplay video conveniently presented.Excellent work!
