OCZ Technology Titan 2 Ultra SE review

Technical features explained

Digital Vibrance Control (DVC)

This supposedly makes the colours more vibrant, the picture sharper & the image more lifelike, although in reality it just increases the contrast of the image.

NVidia Shading Rasterizer (NSR)

Here's what nVidia have to say: "Delivers incomparable resolution and accuracy. Complex scenes are now rich with detail. Features such as per-pixel bump mapping can be utilised to a more dramatic visual effect."

Included with all GeForce 2 cards, this feature is probably noticeable when you compare the image quality of GeForce 2 cards with that of the GeForce 256. Although the image quality is not noticeably better than that of rival cards based on non-nVidia chipsets.

High Definition Video Processor (HDVP)

Incorporating a new per-pixel shading processor. Each of the four new rasterization pipelines process two textures per pixel in 32-bit colour.

Digital Visual Interface (DVI )

An alternative video output, as often used on TFT flat-panels. As the name suggests, it is digital, rather than analogue as used on DSUB connectors, and provides high quality output. DVI is compatible with standards such as VESA, P&D & DFP. Not to be confused with the DVI (Digital Video Interactive) codec.

Second generation Hardware Integrated Transform and Lighting (H/TnL)

H/TnL theoretically massively improves frame rates. It acts to take some of the TnL instructions, mathematics, or vectors away from the CPU and put use the GPU to calculate them, freeing up the CPU. However, it suffers from several drawbacks. Most importantly, games (or more specifically their graphics engines) need to support it, and only newer games do this. Secondly, CPUs are now so powerful that much of the advantage is lost. Thirdly, the instruction set is static & still somewhat limited despite being "2gen". The CPU (or more accurately, the FPU) still gets a lot of vectors to work out before the Titan can render a scene even if H/TnL is enabled. The TnL unit on the Ultra chip is also responsible to some degree for FSAA, when it is enabled.

Twin View

Offers two screens through one graphics card. Formats supported are mirroring (creates a clone desktop) or extended desktop. Not quite as advanced as Matrox's technology but nonetheless welcome, especially on a budget gaming card. The Titan offers a variety of ways to connect devices. Unlike other cards, you can have two monitors connected rather than a monitor and a television, although one must support the digital connection. Unfortunately you cannot use all three outputs concurrently, although I have not been able to test this myself.
