The main difference lies in the manufacturer's artificial market division, and the hardware of the professional card of the game card is the same. However, in order to distinguish the market and increase profits, manufacturers intentionally blocked some OPENGL interfaces of game cards, so game cards support D3D and some OPENGL, and professional cards support D3D and all OPENGL. When the driver is installed, it will be recognized automatically. At present, users cannot forcibly interfere with identification to install other drivers. So people who want to change their cards should give up.
Opengl is the 3D acceleration api of most CAD. The CAD referred to here is not AUTOCAD, but computer-aided design. Three-dimensional animation software (such as 3DS Max, Maya, Softimage|3D, etc. ), rendering software (such as LightScape, 3DS VIZ, etc. ), CAD software (such as AutoCAD, Pro/Engineer, Unigraphics, SolidWorks, etc. ) and model design (such as Rhino).
Game graphics drivers, as well as D3D environment optimization games, show the surface of the object in most cases, and there are few transparent things, let alone what is on the back of the object. That is to say, everything behind the wall is blocked and you don't need to see it. Optimization of this class
For designers, when designing, you should see the internal structure of the object. Almost all the structures work in a transparent and translucent environment with overlapping models. Especially for 3D architectural modeling design, 3D interior design, SolidWorks, and Rhino product appearance design, the whole product is usually presented on the screen to outline whether the product modeling or scene proportion is coordinated, which is more demanding on hardware. However, most structural engineers are used to opening a single part or assembling several groups to make a part. Therefore, although the whole product may have millions of faces in the end, in practical work, there are relatively few polygons in the picture presented by a part design, and there is relatively no requirement for configuration. In a word, professional graphics driver optimizes the transparency, perspective and cross-section display performance of objects. As for how much to improve, you need to experience it yourself.
The game graphics card can also run the above CAD software, but its performance is not high. When you can't run the above software smoothly by using the current mainstream or mid-range game graphics card, such as 1500 yuan graphics card, it doesn't make much sense to change to a fever-level graphics card with a price of 3,000 yuan to 6,000 yuan, and the performance improvement is not great. Redundant graphics cards are in useless blind calculation. At this time, you need to change your professional card. It is recommended not to buy cheap professional cards because they are expensive. Suggest one step at a time. At present, the GPU of 1500 yuan game card is made into a professional card to buy 56000. Almost three times the price. If you use the 1500 game card to check the model jam, 1 frame will be displayed for 3 seconds. So if you buy a 5 6 thousand graphics card, even if the performance is improved by five times, it will take three seconds and five frames, that is, 1.6 frames a second. Generally, smooth movies have 24 frames per second, and smooth games have more than 24 frames per second, preferably 40-60. When the frame is lower than 10 per second, the modeling and drawing are seriously delayed. Below 5 frames, it is no longer efficient, and the operation is extremely inconvenient.
Hardware performance is always limited. If your model is too big, no matter how good the configuration is, there is nothing you can do.
If the budget is enough, it is recommended to do it in one step, because the configuration of modeling will not be eliminated soon, because it is not like a game card, and the new game configuration requires higher and higher resolution every year, and the new game can't be played after two years.
Modeling this kind of thing, you make a rice cooker with 65438+ 10,000 faces this year, and the rice cooker will still have 65438+ 10,000 faces next year, unless you say that you will make a rice cooker this year. Gai Lou and driving next year are really worlds apart.
The above is my personal opinion and the experience of some colleagues and friends at work. It may be wrong, for reference only.
