With graphics business going nowhere SiS decided to get rid of anything not essential for integrated graphics. Therefore, it is safe to say even cheapest cards with 50 MHz memory will outrun fastest Virge. But guess what, you can play some GlQuake on without it, because it is compatible with the S3 Quake wrapper for Virge. Well, there are few hopes: Having AGP boards with all three types of memory, quick answer is possible.

SiS – Wikipedia

Newly formed graphics-only XGI company released second generation Xabre architecture under Volari name with more PR twists and hypes which fire backed pretty heavily and confirmed the underdog position of XGI. At least packs all the basic features needed for proper rendering of 90’s 3d games. The sweet spot is usually at x Real gift is Mpact 2 wrapper, properly working and fastest, it became the choice for first and second Quake engines instead of the ICD.

Silicon Integrated Systems is a Taiwanese corporation founded in I will update this article later if it will be worth it.

In the middle of 3d gaming craze hits full speed and market is supplied 632 products of witty names, sometimes not far from mass murder. Since the beta driver release code named Java with OpenGL ICD was buried in the depths of the internet allow me to save the suffering of other geeks by providing the library here. It steadily grew around core logic and multimedia products. EDO cards are known to be minimally overclockable and mine confirms this after few extra MHz.

For untrained eye no really bad filtering showed up in games. The very first C1 revision features only one 632 coordinate and blending stage and suffers from broken texture perspective correction and fails one advanced blending operation. To be crowned as king of budget few things were missing: Also alpha and scissored planes are tested at render output. SiS remained focused on low-end in and their first Sjs chip “” simply tried to do similar DX7 rendering as competition for “Asian” price.

While driver reports support for all blending modes, actual rendering has issues in modern engines like Half Life and Quake 3.

It was not until that SiS entered the discrete graphics market with 2d chips 6236. I tried both to be sure whether it influences transfers with system memory, but it made no difference. Later 632 shrink and reingeneered with 64 bit memory bus, cheaper “” sold a lot more, but still not enough to regain former market share of It is easy to understand why SiS introduced Xabre family with previously non-existing buzz, older cores got very little space in media.


For discrete graphics SiS prepared bit architecture numberedbut with uninspiring speed and higher cost was barely registered in the retail market. First revision C1 seems to be another chip with broken perspective correction engine. Performance 3d performance of is rather low, unlike what theoretical fillrate suggests it does not have enough power for gaming at x Since the model aimed for low cost over high performance, its capabilities were low compared to contemporary products.

Therefore, it is safe to say even cheapest cards with 50 MHz memory will outrun fastest Virge. But the uncertainty of solid drivers kept retail cold. Third the texturing likes to drop samples at further mip maps, but the amount of shimmering is within expectations of the time.

Then there is a VLIW floating point primitive setup engine capable of triangle setup within 60 clocks. Bilinear filter however is not smooth interpolation, but a gradual.

However cases of unstable textures remained, so it still cannot be considered as correct and accurate per pixel division. Since C5 blending is correct and most of perspective problems are fixed.
