Everything seemed to be in place, and Cirrus promised shipping of first 3D accelerator by the end of Texturing unit works in paraller with polygon engine, available formats include RGBA up to x pixels big. In , Hackworth stepped down and Cirrus went through continues changes. The execution was poor on some other products as well and Cirrus Logic had to go through consolidation after rapid expansion. TextureJet slider is one of those, but I could not get any relevant difference by changing its value. If Laguna3D could draw full featured 3d pixel in single cycle as Cirrus claimed, this should not be a contest, but as you can see it rarely happens.

Anyway, focus then moved onto storage, audio chips and data acquisition technology used for communication and industrial applications. Since most of other accelerators I am comparing don’t have such problems I used the highest quality setting for my tests to get a more leveled conditions. Cirrus was especially fond of it’s texturing engine, calling it TextureJet architecture.

Same thing happens in Ultimate Race Hd5465, but along with very serious bug drawing most of polygons in red color.

For demonstration here are screens from Shadows of the Empire: I would say Cirrus did a fine job on thebut something extra was missing to become gamers choice. I don’t know why exactly Mondello wasn’t finished, but price would probably be quite high and therefore aimed at the professional market. Both 2 and 4 MB variants are common. Laguna3D has pins for second channel already reserved, to maintain the same board layout with future planned products using two channels to double the memory bandwidth.


Smoke in Carmageddon is not bilineary filtered and car shadow flickers, shadows in Expendable are drawn on top, status bar in Formula 1 is broken.

It is nice when accelerator uses higher internal precision, but dither pattern employed by Laguna is far from accurate and several overlapping layers of transparent textures can deliver awful almost stipple-like pattern.

And Cirrus Logic as a whole was bleeding.

World texturing does not work in those, promise of single lighting pass from spec sheets is really only for basic techniques. 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.

Performance, feature set, drivers, image quality, just in all aspects I consider this is a boring gray product, average at best. Clock of Rambus controller is half of data cll, which means own domain ticking at frequency of MHz. Microsoft Gold Certified Company Recognized for best-in-class capabilities as an ISV Independent Software Vendor Solvusoft is recognized by Microsoft as a leading Independent Software Vendor, achieving the highest level of completence and excellence in software development.

Experience First big complaint about image quality is broken texture perspective correction. For demonstration here are screens from Shadows of the Empire:.

Unreal just skips lightmaps alone and Laguna is useless for other effects as well. Inside the chips only other obvious improvement is fixed bilinear filter, which I will co to later.

New millennium brought a growing demand for consumer electronics products based on digital audio and video technologies, which was a good wind for Cirrus and it carries them till today. The AGP version would then be also a bug fixing effort. Solvusoft is recognized by Microsoft as a leading Independent Software Vendor, achieving the highest level of completence and excellence in software development. It takes care of common rendering functions such as Gouraud shading, perspective correction ahemZ-buffering, texture map filtering well After three years of struggle Patil contacted Hackworth, back then in Signetics.

Even if execution units are designed to process multiple operations in single pass, their inputs cannot be fed fast enough. First lowest quality, then default and finally highest. It survives on the fly switch to MHz, but 3d games then quickly freezed PC. Fabrication partnerships with both IBM c, Lucent were ended.

These systems improved hard drive function management and Patil Systems was ggd5465 to market new product. Compatibility with newer game should be minimal, NHL ’99 and Need for Speed 3 cannot be rendered properly.

However highest setting is only marginally slower than default, but still does not provide perfect correction. The CL-GD chip ought to be disappoing, because bilinear texture filter is one of the cheapest possible implemntation. Cirrus abandons PC graphics There was little excitement around Laguna upon release and there is little excitement now when looking back.

That was one big nail into Laguna3D’s coffin, because with advancing time game developers were using it more and more.
