MFAA Technology Recap
In mid-September NVIDIA took the wraps off of the GeForce GTX 980 and GTX 970 GPUs, the first products based on the GM204 GPU utilizing the Maxwell architecture. Our review of the chip, those products and the package that NVIDIA had put together was incredibly glowing. Not only was performance impressive but they were able to offer that performance with power efficiency besting anything else on the market.
Of course, along with the new GPU were a set of new product features coming along for the ride. Two of the most impressive were Dynamic Super Resolution (DSR) and Multi-Frame Sampled AA (MFAA) but only one was available at launch: DSR. With it, you could take advantage of the extreme power of the GTX 980/970 with older games, render in a higher resolution than your panel, and have it filtered down to match your screen in post. The results were great. But NVIDIA spent as much time talking about MFAA (not mother-fu**ing AA as it turned out) during the product briefings and I was shocked when I found out the feature wouldn't be ready to test or included along with launch.
That changes today with the release of NVIDIA's 344.75 driver, the first to implement support for the new and potentially important anti-aliasing method.
Before we dive into the results of our testing, both in performance and image quality, let's get a quick recap on what exactly MFAA is and how it works.
Here is what I wrote back in September in our initial review:
While most of the deep, architectural changes in GM204 are based around power and area efficiency, there are still some interesting feature additions NVIDIA has made to these cards that depend on some specific hardware implementations. First up is a new antialiasing method called MFAA, or Multi-Frame Sampled AA. This new method alternates the AA sample pattern, which is now programmable via software, in both temporal and spatial directions.
The goal is to change the AA sample pattern in a way to produce near 4xMSAA quality at the effective cost of 2x MSAA (in terms of performance). NVIDIA showed a couple of demos of this in action during the press meetings but the only gameplay we saw was in a static scene. I do have some questions about how this temporal addition is affected by fast motion on the screen, though NVIDIA asserts that MFAA will very rarely ever fall below the image quality of standard 2x MSAA.
That information is still correct but we do have a little bit more detail on how this works than we did before. For reasons pertaining to patents NVIDIA seems a bit less interested in sharing exact details than I would like to see, but we'll work with what we have.

Earlier this week, a new product showed up on Gigabyte's website that has garnered quite a bit of attention. The GA-N980X3WA-4GD WaterForce Tri-SLI is a 3-Way SLI system with integrated water cooling powered by a set of three GeForce GTX 980 GPUs.
That. Looks. Amazing.
What you are looking at is a 3-Way closed loop water cooling system with an external enclosure to hold the radiators while providing a display full of information including temperatures, fans speeds and more. Specifications on the Gigabyte site are limited for now, but we can infer a lot from them:
- WATERFORCE :3-WAY SLI Water Cooling System
- Real-Time Display and Control
- Flex Display Technology
- Powered by NVIDIA GeForce GTX 980 GPU
- Integrated with 4GB GDDR5 memory 256-bit memory interface(Single Card)
- Features Dual-link DVI-I / DVI-D / HDMI / DisplayPort*3(Single Card)
- BASE: 1228 MHz / BOOST: 1329 MHz
- System power supply requirement: 1200W(with six 8-pin external power connectors)
The GPUs on each card are your standard GeForce GTX 980 with 4GB of memory (we reviewed it here) though they are running at overclocked base and boost clock speeds, as you would hope with all that water cooling power behind it. You will need a 1200+ watt power supply for this setup, which makes sense considering the GPU horsepower you'll have access to.
Another interesting feature Gigabyte is listing is called GPU Gauntlet Sorting.
With GPU Gauntlet™ Sorting, the Gigabyte SOC graphics card guarantees the higher overclocking capability in terms of excellent power switching.
Essentially, Gigabyte is going to make sure that the GPUs on the WaterForce Tri-SLI are the best they can get their hands on, with the best chance for overclocking higher than stock.
Setup looks interesting - the radiators and fans will be in the external enclosure with tubing passing into the system through a 5.25-in bay. It will need to have quick connect/disconnect points at either the GPU or radiator to make that installation method possible.
Pricing and availability are still unknown, but don't expect to get it cheap. With the GTX 980 still selling for at least $550, you should expect something in the $2000 range or above with all the custom hardware and fittings involved.
Can I get two please?

Today, NVIDIA has announced the November update for their SHIELD Tablet, which is really about three announcements that are rolled up together.
As expected, the SHIELD Tablet is getting a roll-up to Android 5.0 Lollipop and its new, “Material Design” style guide. NVIDIA's took the opportunity to refresh the SHIELD HUB (my shift key must think that this is an MSI announcement by now...) in the same design specification. While interesting, the two other announcements probably beat it out, especially the GRID streaming service (and how it relates to the Xbox One and the PlayStation 4).
But before we get to GRID, let's talk “The Green Box”. In May, NVIDIA sent us a green crowbar to mark the availability of Half-Life 2 and Portal on the NVIDIA SHIELD. These were full, native ports of the PC title to ARM and Android that is exclusive to the NVIDIA SHIELD. With the November update, Half-Life 2: Episode One has also been ported to the platform. The three games, Portal, Half-Life 2, and Episode One, are also packaged in “The Green Box” bundle, which will be included free-of-charge with the SHIELD Tablet 32GB. Note that, while the games are included with the tablet, they require a controller to play, which is not included.
Now we talk about GRID.
Netflix is a popular service where people can watch a variety of movies from their rolling catalog. It will not replace ownership of certain, intrinsically valuable titles, but there is probably options for anyone who wants to consume some form of entertainment. GRID is a similar service for video games, and it is not the first. We took a look at a preview of OnLive in 2010, connecting to a server about 2400 miles away, which is over twice the maximum intended range, and found the experience somewhat positive for games except Unreal Tournament 3 at that relatively extreme latency. Another company, GaiKai, was purchased by Sony and rebranded as PlayStation Now. It will serve up a selection of games from the PS3 catalog. Again, content on these services can be pulled at any time, but if you are just looking for the entertainment value, something else will probably be there to scratch your itch.
The interesting part that I have been teasing throughout this entire post is the performance of NVIDIA GRID. PlayStation Now is rated at 192 GFLOPs, which is the theoretical GPU compute throughput of the PS3's RSX chip. GRID, on the other hand, is rated for 2448 GFLOPs (~2.5 TFLOPs). This is higher than the PlayStation 4, and almost twice the GPU performance of the Xbox One. On the PC side, it is roughly equivalent to the GeForce GTX 760 Ti.
This compute rating has a hidden story, too. Back in 2011, Epic Games demoed “Samaritan” in Unreal Engine 3. This was the bar that Epic Games set for Microsoft, Sony, and Nintendo to mark a new console generation. When Unreal Engine 4 was unveiled at the end of E3 2012, it was embodied in the Elemental Demo, which also ran at (you guessed it) 2.5 TFLOPs. At the PlayStation 4 (1.9 TFLOPs) announcement, the demo was scaled back with reduced particles and lighting complexity. It was not shown at either Xbox One (1.3 TFLOPs) announcement at all.
What all of that means is simple: NVIDIA GRID is the only fixed hardware platform (that I am aware of) to meet Epic's vision of a next-gen gaming system. I say fixed, of course, because the PC can over-double it per card, with some games scaling to four discrete GPUs. This also says nothing about the CPU performance, system memory, or video memory, but it has the GPU in the right place for a next gen platform.
The NVIDIA GRID preview will launch in November for North America, with East Coast and West Coast servers. It will expand in December for Western Europe, and in “Q2” for Asia Pacific. The service will be free for SHIELD users until June 30th, 2015. The Android 5.0 Update for the SHIELD Tablet will be available on November 18th.

It is possible that a shipping invoice fragment was leaked for the NVIDIA GeForce GTX 960. Of course, an image of text on a plain, white background is one of the easiest things to fake and/or manipulate, so take it with a grain of salt.
The GTX 960 is said to have 4GB of RAM on the same, 256-bit bus. Its video outputs are listed as two DVI, one HDMI, and one DisplayPort, making this graphics card useful for just one G-Sync monitor per card. If I'm reading it correctly, it also seems to have a 993 MHz base clock (boost clock unlisted) and an effective 6008 MHz (1500 MHz actual) RAM clock. This is slightly below the 7 GHz (1750 MHz actual) of the GTX 970 and GTX 980 parts, but it should also be significantly cheaper.
The GeForce GTX 960 is expected to retail in the low-$200 price point... some day.

Tagged: asus, strix, GTX 970 STRIX DirectCU II OC, GTX 970, nvidia, maxwell
When ASUS originally kicked off their new STRIX line they gained popularity not only due to the decent overclock and efficient custom cooler but also because there was only a small price premium over the base model. At a price of $400 on Amazon the card has a price inline with other overclocked models, some base models can be up to $50 less. [H]ard|OCP investigated this card to see what benefits you could expect from the model in this review, comparing it to the R290 and 290X. Out of the box the card runs at a core of 1253 -1266MHz and memory of 7GHz, with a bit of overvolting they saw a stable core of 1473 - 1492MHz and memory of 7.832GHz.
With the new price of the 290X dipping as low as $330 it makes for an interesting choice for GPU shoppers. The NVIDIA card is far more power efficient and the fans operate at 0dB until the GPU hits 65C, which [H] did not see until after running at full load for a time and even then the highest their manually overclocked card hit was 70C. On the other hand the AMD card costs $70 less and offers very similar performance. It is always nice to see competition in the market.
"Today we examine ASUS' take on the GeForce GTX 970 video card. We have the ASUS GTX 970 STRIX DirectCU II OC video card today, and will break down its next-gen performance against an AMD Radeon R9 290 and R9 290X. This video card features 0dB fans, and many factors that improve its chance of extreme overclocking."

Check out the video for a look at the various in game enhancements that NVIDIA's new feaures will be bringing to FarCry 4 and gaze in awe at that gorgeous yak featured at 1:37, just look at its hair waving in the breeze and reacting to the motions of the animal. It is not clear if AMD's TressFX will provide equivalent body and shine to the beasts that HairWorks does but you have to admit that is an impressive amount of work to make meat on the hoof look pretty. There are two different technologies to improve the look of shadows, Percentage Closer Soft Shadows (PCSS, aka ShadowWorks) softens the edges of shadows based on the distance between the object creating the shadow and the surface the shadow appears on while Horizon Based Ambient Occlusion (HBAO+) is a new and efficient way to render ambient lighting and shadows accurately without paying for it with a big hit in performance. Temporal anti-aliasing, TXAA is reputed to offer the benefits of MSAA 8x at the performance cost of 4x; while it is hard to judge the accuracy of that in the video you can certainly see it is an effective way of removing jaggies from straight edges. You can also expect to see God Rays rendered properly, the shot of the sun through the tree near the end makes a rather nice set peice to display that effect.
Below you can see the recommended hardware, it is worth emphasizing that only 64bit OSes need apply on the PC.

NVIDIA has introduced a promotion to compete with AMD's Never Settle Forever program. The Pick your Path bundle offers purchasers of GTX 980, 970, 780 Ti, or 780 cards or who have bought notebooks with a GTX 980M or 970M the choice of one of three games. These titles include The Crew, Far Cry 4 and Assassin’s Creed Unity, all of which feature optimization taking advantage of NVIDIA's new HBAO+ and TXAA technologies, enhanced performance at 4k resolutions and other game specific benefits such as the tessellation in Assassin's Creed. This promotion will run until the end of the year so if you had planned on upgrading your hardware to play one of these games it makes NVIDIA's solutions a little more attractive.
SANTA CLARA, Calif.—Nov. 4, 2014— NVIDIA today announced a new technology PC gaming development partnership with Ubisoft that will bring consumers closer to their games than ever before.
Thanks to the power of NVIDIA GeForce GTX technology, including the just-released GTX 980 and 970 GPUs, this holiday’s hottest games, Assassin’s Creed Unity, Far Cry 4 and The Crew, will look simply incredible. By integrating NVIDIA’s superior GameWorks technologies, such as HBAO+ for realistic shadows, TXAA for cinema quality smoothness, as well as enhanced 4K support, Ubisoft is delivering cutting-edge content that allow PC gamers to become fully immersed in their gaming environments.
Part of the “Pick Your Path” promotion which kicks off this week and runs to the end of the year, gamers who purchase a qualifying GeForce GTX GPU, including a GeForce GTX 980, 970, 780 Ti, or 780 graphics card or a notebook with GeForce GTX 980M or 970M get their choice of which title--The Crew, Far Cry 4 or Assassin’s Creed Unity--to add to their library for free.
“NVIDIA has worked hard, hand-in-hand with our development teams, to help provide the best experience for our PC players,” said Jean-Francois St.Amour, Lead Graphics Programmer at Ubisoft Montreal. “Their support and insight is even more important now, as we make a big technological leap into the next-generation of Assassin’s Creed games.”
Assassin’s Creed Unity, the latest installment in Ubisoft’s most successful franchise, will feature HBAO+, TXAA, PCSS and tessellation technologies which allow Ubisoft to realistically render the 16th century game environments, which are set in Paris during the French Revolution.
Another legendary game series getting a massively visual and technology upgrade is Far Cry 4. In addition to HBAO+, TXAA, PCSS and enhanced 4K support, Far Cry 4 also integrates NVIDIA Godrays technology so gamers can feel the sun beating down in the Himalayas, and NVIDIA HairWorks, for rendering the realistic, but deadly adversaries that will be encountered in the game.
And finally, if horsepower, engines and pound per cubic feet rev your receptors more, then The Crew, the ultimate street racing game ever made, may be just the ticket you’ve been waiting for. Motoring through the bustling streets of New York City and Los Angeles, cruising down sunny Miami Beach or trekking through the plateaus of Monument Valley never looked so superb thanks in part to the integration of HBAO+ and TXAA technologies-- all rendered in breathtaking 4K. The Crew even comes with an Android companion app that lets you tinker with your ride before playing it live, chat remotely, browse friend profiles, and send your crew on jobs – all from the road.

Just in case you need a reason to be insanely jealous of someone, [H]ard|OCP has just published an article covering what it is like to be living with two GTX 980's in SLI. The cards are driving three Dell U2410 24" 1920x1200 displays for a relatively odd resolution of 3600x1920 but apart from an issue with the GeForce Experience software suite the cards have no trouble displaying to all three monitors. In their testing of Borderlands games they definitely noticed when PhysX was turned on, though like others [H] wishes that PhysX would abandon its proprietary roots. When compared to the Radeon R9 290X CrossFire system the performance is very similar but when you look at heat, power and noise produced the 980's are the clear winner. Keep in mind a good 290X is just over $300 while the least expensive GTX 980 will run you over $550.
"What do you get when you take two NVIDIA GeForce GTX 980 video cards, configure those for SLI, and set those at your feet for four weeks? We give our thoughts and opinions about actually using these GPUs in our own system for four weeks with focus on performance, sound profile, and heat generated by these cards."
