With the release of the Catalyst 12.2 WHQL drivers AMD has made available the official support for Crossfire in stereo 3D mode (previously only available in beta drivers) and as I’ve promised I did some testing to see how the Radeon HD 7970 will scale its performance in stereo 3D mode with a single and dual cards in Crossfire. I’ve used the 23-inch LG D2342P passive 3D monitor along with the TriDef 3D software as a middle-ware providing the stereo 3D support in games. Then a few more demanding in terms of performance games were ran with a single Radeon HD 7970 and with a dual HD 7970s in Crossfire in stereoscopic 3D mode and you can find the average framerate that was achieved below.
- Motherboard: Gigabyte X79-UD3
- Processor: Intel Core i7 3960X @ 4.6 GHz
- Memory: 8 GB Exceleram DDR3-1600
- Storage: 120 GB Intel X25-M SSD
- OS: Windows 7 Professional 64-bit
- Video card: Radeon HD7970s with Catalyst 12.2 driver
- 3D Monitor: 23″ LG D2342P-PN (Passive 3D)
- 3D Middleware: DDD TriDef 3D 5.1 software
Games were tested on 1920×1080 resolution with maximum detail settings and 4xAA enabled where available (AAA for Metro 2033 with DOF disabled), unless AA gets forced to disabled from the software in order to get better performance. Have in mind that the framerate in the table and graph is per eye, the graphics card actually needs to render twice that number of frames, so each eye gets a slightly different perspective in order to create the 3D image.
As you can see from the results when the Crossfire is working as it should in stereo 3D mode there is quite nice scaling in terms of performance when you add in a second video card. But considering the fact that the games used for testing are all popular titles and have been available for a while already there were some surprises. For example there was no scaling in terms of performance at all in Skyrim, Mafia II did not run in Crossfire by default, but when forced it worked just fine and scaled well, and F1 2011 was just crashing with Crossfire enabled. Also take a look at the average framerate achieved with a single card in stereo 3D mode, a bit on the edge for comfortable gaming… meaning that you should compromise a bit on detail levels or extra filtering settings and that is the current flagship GPU from AMD. But still the addition of Crossfire support in stereo 3D mode is a good thing finally happening after a long wait, so now you can actually add a second card and get a performance boost over the not so good framerate you may be getting in stereo 3D mode, and up until a few months you could not do that. Now, another interesting question is how does the Radeon HD 7970 compare to the newly released GeForce GTX 680 in stereo 3D mode and I’m sure that there are a lot of people wondering about that already…

Following the release of the TriDef 3D Ignition 3.5 Beta 1 last month, now comes a new official release in the form of TriDef 3D 5.2. The new official version pretty much includes what the Beta release of the Ignition software introduced with a few more updates.
TriDef 3D 5.2 Release Notes:
TriDef 3D Ignition
- Virtual 3D has been improved in terms of both quality and performance and renamed to “Power 3D” (DX 9 only, so far – DX10/11 Power 3D optimisations coming soon)
- Improved DirectX 10/11 game performance (Battlefield 3 in particular)
- Added support for Need For Speed: The Run, SOL Exodus, Unstoppable Gorg, Alan Wake, Trine 2, Microsoft Flight, Torchlight, APB, Tribes Ascend Beta, Blacklight Retribution and various other games
- Improved the following game profiles: Call of Duty: Black Ops, Call of Duty: Modern Warfare 3, Sonic Generations, Batman: Arkham City, RayCity and other games
TriDef 3D Media Player
- Fixed an issue which caused 3Di DVDs to playback incorrectly
The DDD TriDef 3D software package enables the viewing of movies, photos and games in stereoscopic 3D mode on compatible hardware, it is one of the two middle-ware solutions (the other being the iZ3D driver) used for ensuring stereo 3D support on AMD hardware (apart from the few games that support natively the AMD HD3D technology), but the software is also compatible with Nvidia-based video cards as well.

AOC has introduced a new 23-inch passive 3D-capable monitor with that is only 10.6 mm deep and with a thin 5.8 mm frame – the AOC d2357Ph. The design definitely catches your attention, and thanks to the thin bezel you might want to consider using these monitors for multi-monitor setups in 2D or stereo 3D. AOC d2357Ph uses LED backlight and thus achieves the thin design, although it even has integrated speakers, supports HDMI 1.4 interface with frame packaging as well as row interleaved 3D and comes with a 2D to 3D conversion capabilities.
AOC d2357Ph 3D Monitor Specifications:
- Panel Size: 23 inch/58.5 cm, 16:9, Full HD, WLED LCD
- Response Time: 2ms in 2D mode (Grey to Grey), 5ms (typical)
- Maximum Brightness: 2500 cd/m²
- Maximum Contrast: 20,000,000:1 (dynamic), 1000:1 (typical)
- Viewing angle: 170º (H)/170º (V), @ C/R > 10
- Pixel pitch: 0.265 mm
- Signal Input: 2x HDMI 1.4, VGA (Analogue)
- Power consumption: On: < 36 W; Standby: < 0.6W
- Product with stand: 533.3 x 399.3 x 120 mm
- Product with stand: 4.87 kg
The new 3D monitor from AOC comes with 2 pairs of polarized 3D glasses, 1 normal and 1 clip on for people wearing prescription glasses. And although it is not mentioned, the monitor should be coming with the TriDef 3D software bundled for the stereo 3D support as AOC is an OEM partner of DDD and there is a special version of the TriDef 3D package intended for AOC 3D monitors. The AOC d2357Ph is scheduled to be launched in April 2012; the recommended retail price will be 239 Euro in Europe, not yet information about pricing and availability in North America. Considering the price of the previous 23-inch passive 3D monitor from AOC (the e2352Phz available for $299 USD), you can expect that the AOC d2357Ph should be available at a similar or a slightly higher price.
