Outside of Id world I tried Star Siege, again succesfully. In they introduced their own 3d accelerator, gaining a significant foothold with one million chips sold, and delivered world first motherboard chipset with integrated graphics core. Major flaw is how some 2d images seem distorted, for example characters in Myth or fonts in Incoming and Unreal. In Expendable and Resident Evil C1 rendered utter garbage. Which makes little sense to me, SiS at that time had to know performance of is too low to become gamers choice, but it still could be good multimedia product.

Even some 2D elements like HUDs can float by few pixels here and there. The image quality of AGP is fine but few things are still lowering overall impression.

In Expendable and Resident Evil C1 rendered utter garbage. Common bug is found in Grim Fandango, where wrong z occlusion makes characters hide behind some backgrounds.
It was not until that SiS entered the discrete graphics market with 2d chips 62xx. Texturing engine is flexible, handling rectangular shapes up to x and color formats from smallest palettes over mixed modes to 32 bit RGBA. Outside of Id world I tried Star Siege, again succesfully.
SIS 6326 2X AGP 8MB
Image quality issues are the same as with C1, but was memory management improved by AGP? Therefore, it is safe to say even cheapest cards with 50 MHz memory will outrun fastest Virge.
For untrained eye no really bad filtering showed up in games. It is a bad sign when company concentrates on promoting interface rather than compute power of the chip itself.
Local memory management is problematic as well, games like Formula 1 or Motoracer 2 requiring minimum of four megabytes can reject the card- perhaps precious kilobytes allocated for Turbo Queue are to blame. Anyway, once SiS polished the silicon became solid value 3d chip.
But finding earlier chips was quite though, it seems most cards were by far equipped with the AGP version, no matter which bus they utilized.
Back then all three cards in my possession were this version anyway. Having started testing with Windows 95 I used last driver for the system- 1. First review was done with AGP even if its release date is on the edge of my scope. I tried C5 and these bugs are gone.
Although its performance was low compared to the GPUs of its age, eventually it became very successful, specially integrated in many motherboards designed to the corporate market, where the low cost is prioritized over 3D performance.
SIS 2X AGP 8MB Overview – CNET
I guess it would not fit well. SiS was abandoning other challenging products through the years, sold it’s fabs and today does not offer any key PC core logic anymore, despite buying back rest of XGI in But the uncertainty of solid drivers kept retail cold.
At least chipsets business was again gaining momentum thanks to some great innovative designs. Silicon Integrated Systems is a Taiwanese corporation founded in First revision C1 seems to be another chip with broken perspective correction engine. With graphics business going nowhere SiS decided to get rid of anything not essential for integrated graphics. 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 apg.
But guess what, you can play some GlQuake on without it, because it is compatible with the S3 Quake wrapper for Virge. I will update this article later if it will be worth it.
Many textures on large polygons are warped, 3626, sometimes even rotated. To see screenshots of AGP visit this gallery. Vertex fog is properly blended with all surfaces. 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.
Four megabytes of video memory are sometimes not enough, C1 did not use texturing agpp system memory and dropped some textures in Incoming.
