This page describes different series of video cards (which are also known as Graphics Processing Units (GPUs) or Graphics Cards), listing the series which meet at least the most basic technical requirements for the Visual3D Game Engine, specifically that they support DirectX 9.0c (Shader Model 3.0) or later version (such as DirectX 10 or DirectX 11), as well as describing their relative performance and likelihood of their being usable for different graphics quality settings for different types of games/applications.
Note that DirectX 9.0 (as opposed to "9.0c") only provides Shader Model 2.0, and therefore won't support all engine features (such as newer terrain and particle effects), such those video cards aren't included here.
In short, video cards which support DirectX 9.0c include:
NVIDIA GeForce 6 (6xxx), GeForce 100 series, ATI Radeon X1300, Radeon HD, and above (also most NVIDIA Quadro and ATI FireGL, FireStream, and FireMVNVIDIA Ion), and, at the lowest-end, IGPs like Intel HD Graphics, AMD Fusion, and NVIDIA Ion
Though the cards described here provide the most basic technical support required for the engine to run, that does not guarantee they will provide acceptable performance (FPS) or visual quality, as that depends on how much and how complex the content (models, terrain, shaders, etc.) used in a game or simulation are, and depends on what the specific video card model and how much video memory it has, as well.
Keep in mind when selecting a video card or checking to see if it meets minimum requirements for your Visual3D-powered application, that acceptable performance for a video card (in terms of reaching a usable number of frames-per-second (FPS) such as at 15 to 30 fps) is a not guaranteed (even at the lowest graphics settings) just because a graphics card is new, as ever series of graphic cards includes a few low-end ones (such Each series of video cards usually has its few lowest numbered models as the "non-gaming" model, which often much less powerful than a mid-end model of previous series (for example, the low-end model would be, for NVIDIA, a GeForce 100 (vs. 180) or 9300 (vs. 9800) or, for ATI/AMD, a Radeon HD 2350 (vs. HD 2900)). Also, this guide is based on general benchmark data that is available for graphics cards, summarized in order to provide some general guidelines and suggestions for what wight or might not work well with your game built on Visual3D (or any 3D application, in general), as well as links to tools you can use to compare graphics cards before buying one.
At the time of writing, the ATI, NVIDIA and Intel graphics cards (and Integrated Graphics Processors / IGPs) which support at least DirectX 9.0c (Shader Model 3.0) are the series (and model number ranges and exception cases) described below. Also, all new graphics cards and IGPs support DirectX 9.0c, so that can usually be assumed for any newer video card series not yet added to this list.
Intel HD Graphics 3000 or 2000 (included into the 2nd generation (Sandy Bridge) Core i3/5/7-2xxx processors) - might support lowest graphics settings for some games (as it provides about 14% the performance of highest-end cards)
Intel GMA HD (HD Graphics) (integrated into original Core i3/5/7-xxx processors or the Sandy Bridge Pentium and Celeron processors) - unlikely, but might support lowest graphics for some games/simulations without much content, as it provides about half the performance of Intel HD Graphics 3000 (with about 7% of the highest end cards performance)
Intel GMA 4500 or X3000 (not supported for GMA 3150 or below, such as GMA 950 or GMA 900)
For a better idea if a specific video card model is recommended or usable (likely to provide acceptable performance / FPS for at least medium quality settings, etc.) you can find its rating (eg. in percent relative to the current highest-end video card), such as are available at PassMark Video Card Benchmarks (or PassMark's charts for High vs. Mid vs. Low-end video cards),or, for notebook / mobile video cards and integrated graphics processors (IGPs), you can compare them (as a percentage of the current highest-end video card) at NotebookCheck's Comparison of Laptop Graphics Cards.
