DX9+SSAO: Mafia II

Mafia II is a single-player third-person action shooter developed by 2K Czech for 2K Games, and is the sequel to Mafia: The City of Lost Heaven released in 2002. Players assume the life of World War II veteran Vito Scaletta, the son of small Sicilian family who immigrates to Empire Bay. Growing up in the slums of Empire Bay teaches Vito about crime, and he's forced to join the Army in lieu of jail time. After sustaining wounds in the war, Vito returns home and quickly finds trouble as he again partners with his childhood friend and accomplice Joe Barbaro. Vito and Joe combine their passion for fame and riches to take on the city, and work their way to the top in Mafia II.

Mafia II is a SSAO-enabled PC video game built on 2K Czech's proprietary Illusion game engine, which succeeds the LS3D game engine used in Mafia: The City of Lost Heaven. In our Mafia-II Video Game Performance article, Benchmark Reviews explored characters and gameplay while illustrating how well this game delivers APEX PhysX features on both AMD and NVIDIA products. Thanks to DirectX-11 APEX PhysX extensions that can be processed by the system's CPU, Mafia II offers gamers is equal access to high-detail physics regardless of video card manufacturer.

Long ago I came to the realization that as I continued to build, re-build, and enjoy computers as a hobby, as well as for work, that one constant would be in play: continuous performance improvements. This is just another of those "wow" products. There've been many, but this kinda stands out in it's own way. 6990. Can't wait for the 18125's. Hope I'm around that long.

At the rate we're seeing overlapping improvements we'll see something twice as fast in less than two years.

I just ordered mine on the Egg about 3 minutes ago. I'll make my own personal comments after giving it a whirl in my personal world. I might be eating my words from previous posted comments, lol, oh well, as life goes.

to be continued..............

# 256bit?zac 2011-03-17 21:25
Is this 256bit? Or 256x2bit?
And if it is only 256-bit video frame buffer, why? Or how? previously all dual gpu setups had 2x the memory controller.

Like the I explain in the article, this product has two GPUs on one PCB. Each GPU offers a 256-bit memory bus to the video frame buffer. Having two GPUs won't make single 512-bit lane, but will double bandwidth to 2x 256-bit.

# AMD 6990 reviewsJ.King 2011-06-27 22:03
Correct me if I'm wrong but as far as I can tell ALL the 6990's are made in exactly the same place. IE the card's are all identical except for the stickers on the front. So why the price difference? This was true for the 6950's and 6970's until recently when a bait and switch was pulled by various manufacturers XFX comes to mind. The card's were changed (BIOS switch was removed and other less obvious changes) but the model number's remained the same and they were still being sold as reference.

You are mostly correct. There are some differences depending on what the partner pays for (cooling/BIOS/overclock), but the engineering is generally all done by the manufacturer. There are a few who receive the engineering and make their own PCB, but it's rare. As for pricing, you'll have to take that up with the brands and retailers.
