Then Cirrus Logic embraced graphics and communications products. This website is using cookies. It may also be the reason for no OpenGL games support. But some games don’t like textures outside of local memory, like Viper Racing shows by switching to very small mipmaps, and Incoming drops texturing completely. The AGP version would then be also a bug fixing effort. For demonstration here are screens from Shadows of the Empire:

The AGP version would then be also a bug fixing effort. Flexible yet fabless way was to at least buy long term foundry capacity.

Creative once again bought rights for early release, and more interestingly, they announced their Laguna3D will be compatible with CGL.

Reflection mapping in Monster Truck Racing 2 brakes car texturing.

The texture manager is supported with 1 kilobyte texture cache and on-chip address translation table that tracks, via dynamic random accessing, all the memory locations of textures being used. The first chip obviously did not come in expected shape.

World texturing does not work in those, promise of single lighting pass from spec sheets is really only for basic techniques. Then there is rather heavy dithering to 16 bit colors. It may also be the reason for no OpenGL games support.


M2, on paper at least, was no joke with half million polygons triangle setup and million pixels per second fillrate. Hackworth joined Patil Systems as president and CEO of new company reincorporated in California and named after cirruses, the highest clouds in the sky, as a way of expressing the elevated complexity of its gd546. Then Cirrus Logic embraced graphics and communications products. Better than nothing, but magnified textures will still be blocky.

Cirrus Logic went public in and accelerated growth through acquisitions among which were Pixel Semiconductor and Acumos. TextureJet slider is one of those, but I could not get any relevant difference by changing its value.

Compatibility with newer game should be minimal, NHL ’99 and Need for Speed 3 cannot be rendered properly. Pixels are tested by masks and depth comparison performed with help by cache, before lighting and blending is processed.

No other 3d graphics provider got such an endorsement from mighty Wintel. That was one big nail into Laguna3D’s coffin, because with advancing time game developers were using it more and more. For demonstration here are screens from Shadows of the Empire:. In April Cirrus has licensed the 3D fd5465 of 3DO’s M2 technology, a bit graphics acceleration built for new console.

Both 2 and 4 MB variants are common. And Cirrus Logic as a whole was bleeding. Inside the chips only other obvious improvement is fixed bilinear filter, which I will get to later.

For more screenshots see the Laguna3D gallery. Gd565 stood behind his fab investments because Cirrus in its peak had to redesign multiple times for several manufacturers to meet customers demand.

A year later came second joint fabrication venture with Lucent named Cirent.

Initial promotion gd54465 of hundred bucks should be a sign that Laguna3D is not so hot performer. It survives on the fly switch to MHz, but 3d games then quickly freezed PC. Experience First big complaint about image quality is broken texture perspective correction. Fabrication partnerships with both IBM and Lucent were ended.

Finally, there are many small problems caused by missing multiplicative alpha blending or driver bugs. Laguna3D PCI merely once calculates interpolated color between pixels and uses that, effectively doubling their amount.

The lack of major differences between and puts execution of Cirrus into question, Could they just stay idle while waiting for Intel LX AGP chipset release in August ? Taking price into account it performs quite well in old games even with small amount of local memory.
