Quite a family and considering vendors had liberty to use any memory they liked, there is a large variety of cards. Did they think people will remember random numbers? At one moment SiS was the only company in the world besides Intel with a full portfolio of 3C technologies, including CPU, core logic, 3d graphics, connectivity and advanced wafer fabrication. From Wikipedia, the free encyclopedia. This page was last edited on 27 August , at However cases of unstable textures remained, so it still cannot be considered as correct and accurate per pixel division. On the internet was circulating information about the 2d engine being limited to 4MB of memory, but this seems to be true only for legacy VESA modes.

Views Read Edit View history. Incoming did not drop textures and Formula 1 could start, but look at the mess: At least packs all the basic features needed for proper rendering of 90’s 3d games. Since the model aimed for low cost over high performance, its capabilities were low compared to contemporary products. Third the texturing likes to drop samples at further mip maps, but the amount of shimmering is within expectations of the time.
Many textures on large polygons are warped, shaking, sometimes even rotated. Conclusion and decline of SiS in Windows worked to my satisfaction and with rather robust multimedia software, which was typically bundled with those cards it probably was good and cheap universal graphics card for people not demanding high gaming performance.
The start however was rather rough. But drivers with low quality texturing by default were cheap and Xabres just did not have enough hooks to turn the tides. First revision C1 seems to be another chip with broken perspective correction engine.
SiS later doubled those stages, perhaps in C3 already. Z-buffer is implemented with rejection of hidden pixels in front to back sorting. Here is the gallery to see more.
If only the OpenGL library did not end up with beta release While driver reports support for all blending modes, actual rendering has issues in modern engines like Half Life and Quake 3. Texturing engine is flexible, handling rectangular shapes up to x and color formats from smallest palettes over mixed modes to 32 bit RGBA. For discrete graphics SiS prepared bit architecture numberedbut with uninspiring speed and higher cost was barely registered in the retail market.
Among those SiS drops it’s 3d junior called First 3d architecture of SiS exhibits Direct3d compatibility on par with legends of its generation. But discrete chips sold quite impressive 7 million during alone, pushing SiS into top five.

626 Expendable and Resident Evil C1 rendered utter garbage. I tried both to be sure whether it influences transfers with system memory, but it made no difference.
For untrained eye no really bad filtering showed up in games. EDO cards are known to be minimally overclockable and mine confirms this after few extra MHz. It is easy to understand why SiS introduced Xabre family with previously non-existing buzz, older cores got very little space in media.

It is very annoying ssis absolutely inexcusable bug seen in whole family. The image quality of AGP is fine but few things are still lowering overall impression. Bilinear filter however is not smooth interpolation, but a gradual. These should not be related to such filtering optimization. Thanks to that I saw properly lighted Unreal which does not happen with last Windows 98 driver.
Most of the cards have a jumper to enable own interrupt handling. In SiS pumped out Xabre graphics cores and long overdue holy grail of the company: Then there is a VLIW floating point primitive setup engine capable of triangle setup within 60 clocks. Anyway, once SiS polished the silicon became solid value 3d chip.

All of them are equipped with 8 MB of different memory type, memory bus width is casual 64 bit. Major flaw is how some 2d images seem distorted, for example characters in Myth or fonts in Incoming and Unreal. I have to comment on 2d speed as well.
