Without own fabrication microchips from outside foundries were used. Emulated Cirrus Logic graphic cards are used in emulators. 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. Promised fogging is failing across game suit. Retrieved from ” https: It survives on the fly switch to MHz, but 3d games then quickly freezed PC.

When Intel announced they were entering the 3D market with the i Cirrus Logic exited the market, which at the time for Cirrus Logic was worth million dollars annually. Cirrus was cirru fond of it’s texturing engine, calling it TextureJet architecture. For more screenshots see the Laguna3D gallery. 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.

Creative once again cifrus rights for early release, and more interestingly, they announced their Laguna3D will be compatible with CGL. The first chip obviously did not come in expected shape. Same thing happens in Ultimate Race Pro, but cirrrus with very serious bug drawing most of polygons in red color.

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.


Lkgic company announced in April that it had completed moving its headquarters to Austin, Texas. Michael Hackworth was named president and chief executive officer in Januaryand served as CEO until February By the end of Laguna3D was ready for mass production, but the specifications were nothing like M2.

When the announced release date of the GD “Mondello” came and went, Cirrus’s reputation in desktop PC-graphics suffered. Space dust and engine trails in Homeworld are opaque and single color.

In the early s, Cirrus Logic was a supplier of low-cost PC graphics chips. 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.

So there are different opinions whether the company was mismanaged or victim of its own success. Cirrus got a jump start into 3D technology by acquiring patents and several engineers of Austek, company which has just developed A OpenGL accelerator. Hackworth stood behind his fab investments because Cirrus in its peak had to redesign multiple times for several manufacturers to meet customers demand.

Everything seemed to be in place, and Cirrus promised shipping of first 3D accelerator by the end of Incoming in 32 bit mode, no sign of dithering, but broken lens flares still ruin the show.

3-Channel, Single Phase Power/Energy IC

There are more interesting settings to play with in Laguna registry, though they seem mostly applicable only for AGP version of Laguna3D. Cirrus Logic acquired Crystal Semiconductor, a supplier of analog and mixed-signal converter ICs, in TextureJet slider is one of those, but I could not get any relevant difference by changing its value.


The CL-GD chip ought to be disappoing, because bilinear texture filter is one of the cheapest possible implemntation.

No other 3d graphics provider got such an endorsement from mighty Wintel.

It may also be the reason for no OpenGL games support. Clock of Rambus controller is half of data rate, which 54664 own domain ticking at frequency of MHz. Please help improve this article by adding citations to reliable sources.

Performance, feature set, drivers, image quality, just in all aspects I consider this is a boring gray product, average at best. It joined the Nasdaq market listing in symbol:
