	Fixed Frequency FAQ --How does a 3D graphics accelerator work? -- MonitorWorld.com
		The way that 3D objects are traditionally represented is using a meshwork of polygons - usually triangles - to describe their outside surface.
		This process is called rendering, and involves equations for tracing from the viewer through the scene, equations for determining how light is reflected from light sources, off of objects and back to the viewer, and algorithms for determining which objects in the scene are visible, and which are obscured.
		However, most of the 3D video hardware is proprietary, which means that without a driver, an application developer would have to write a version of their program for each 3D graphics card available.

	Graphics processing unit - Wikipedia, the free encyclopedia
		In the early and mid-1990s, CPU-assisted real-time 3D graphics were becoming increasingly common in computer and console games, which lead to an increasing public demand for hardware-accelerated 3D graphics.
		Initially, performance 3D graphics were possible only with separate add-on boards dedicated to accelerating 3D functions (and lacking 2D GUI acceleration entirely) such as the 3dfx Voodoo.
		They were initially used to accelerate the memory-intensive work of texture mapping and rendering polygons, later adding units to accelerate geometric calculations such as translating vertices into different coordinate systems.

	messiahorchestra.com (3D Accelerator Card Technology)
		3D graphics processing begins with 3D physical modeling and geometry transformations, lighting, and clipping, which are floating-point intensive.
		Today's graphics accelerators are now so fast that the CPU cannot always provide data fast enough to keep up.
		Overall 3D graphics performance is thus often limited by the floating-point calculation speed of the CPU at the beginning of the graphics pipeline.

	HP CCN - Sepia: scalable 3D compositing using PCI Pamette white paper
		When a 3D image is to be computed, the task is spread on all the rendering nodes, each of them computing a sub-set of the problem.
		In the case of 3D rendering, the 3D accelerator will always be more cost-efficient than the FPGA for the functions supported by the hardware.
		In the face of a large number of unknowns (3D accelerator performance and control, Colorado 2 interfacing and performance), the FPGA solution is flexible enough to adapt to all the potential optimizations or problem solutions.

	PowerPlugs: 3D TitlesTechnical FAQs
		For computers with 3D accelerated display hardware there are three files that must be together in the same folder for the presentation to work properly.
		The amount of video RAM with your 3D graphics accelerator may be inadequate for the resolution and/or color bit depth settings at which you are playing back your 3D enhanced presentation.
		It is possible that the 3D title effects may not play back when the position of the mouse cursor is within the text box boundaries of a slide.

	Graphics Accelerators
		One reason the accelerator can be more efficient than the CPU is because it lives closer to the graphics memory; it does not have to transfer raw pixel data over a slow (relative to the speed of the graphics RAM) general BUS and chipset.
		One of the bottlenecks of the earlier graphics accelerators was that the queue would often be too small (typically 16 entries, as is the case of the original ATI Mach 64) to give the host and the graphics accelerator sufficient opportunity for parallelism.
		In a typical situation, many accelerator based operations may be pending or in mid-flight, but all of a sudden, host PCI based requests are issued, which necessarily causes the accelerator to suspend its operation and to flush out the internal graphics memory arbiter (PCI transactions must take precendence over other device memory access).

	What is a 3D Accelerator? (Site not responding. Last check: 2007-10-25)
		While the Accelerator is readily able to process 64 or 128-bit data at a time, regular central processors must take it slower and only go through 32-bits in the same amount of time.
		Because an Accelerator is purchased to boost the speed of its function, this processing time is often compared to the output given from the original processor within the computer.
		Without a three-dimensional accelerator, people will also face the problem of slower processing times for the rest of their computer's tasks, as the central processor attempts to deal with creating 3D images.

		Accelerated Graphics Port (also AGP) - An expansion bus (a nice little slot on the motherboard which allows for expansion of a PC or customization of it when first being built) that was specifically developed by Intel for video cards, AGP is the current standard for video adapters.
		Although most of the information processed by an accelerator must still take a visit to the CPU, substantial increase in speed, quality, and performance of specific information is present with an accelerator.
		3D accelerators can be written to run with an API (that was written to run with a game, that was also written to run with that API).

		There are numerous 3D chipsets being worked on, but these 2 happen to be the ones I have detailed information both on the chips and on boards built using them.
		They mention texture mapping acceleration, but on the 300SX texture maps are held in host memory and per pixel information is sent to the chip which performs the necessary interpolations and applications.
		Traditionally, 3D graphics were created by drawing large numbers of successive polygons using the CPU, which resulted in a tradeoff between detailed graphics and speed of interactivity.

	3D Card Tour (Site not responding. Last check: 2007-10-25)
		A 3D accelerator is laid out on a printed circuit board (PCB), which has multiple layers--typically four to six--depending on the requirements for the particular product.
		The data is typically sent to the 3D accelerator across a dedicated point-to-point interface.
		If new texture data were being sent to the 3D card across the PCI bus for every frame that a 3D accelerator was rendering in a scene, for example, the texture data per frame would need to average just shy of 2MB in size to render at 60fps, which would max out PCI bandwidth.

	3D Accelerator Card Reviews \| Tom's Hardware
		Alternatively to a special 3D chip support, many new games are using Direct3D's new features quite heaviliy, so that it depends on how well the 3D card's driver translates Direct3D to their proprietary engine.
		The only 3D chip to my knowledge, that doesn't have a dedicated 3D engine, but is using Direct3D as its API directly, is NVidia's RIVA 128 chip, currently the fastest Direct3D chip available on the market.
		A 3D chip can only support a special amount of 3D features, others are either not supported at all, or special drivers are used that emulate these features.

		The reason, only cause I am looking to upgrade my 3D card and there are many if's, and's or but's concerning the latest and next generation of video cards.
		I don't like to post frame rates cause it is the perception of speed and smooth movement that matters to me. I don't see any difference in a game running at 70 fps compared to 85 fps, for instance, so fps's don't sell me on a card.
