Voodoo Banshee or Cirrus Logic Laguna? Thu Oct 02, 5: InHackworth stepped down and Cirrus went through continues changes. Everything seemed to be in place, and Cirrus promised shipping of first 3D accelerator by the end of Cirrus got a jump start into 3D technology by acquiring patents and several engineers of Austek, company which has just developed Laguuna OpenGL accelerator.
The goal of Cirrus was to create a high-end card by integrating 3DO's technology into own architecture.
Setting the lowest value gives Laguna a speed increase, but perspectives are getting really fuzzy. But Panasonic in the end decided not to deliver second 3DO to the market.
Even if execution units are designed to process multiple operations in single pass, their inputs cannot be fed fast enough.
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 ? Cirrus abandons PC graphics There was little excitement around Laguna upon release and there is little excitement now when looking back. Experience First big complaint about image quality is broken texture perspective correction. Ars would be an excellent platform to launch something like this off of too.

Default setting is quite high, but still some large flat surfaces have problems, for example you may see shaking ground in Mechwarrior 2. It was in similar market segment, and suffered from it's own blending and perspective correction problems. 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.
Rambus memory controller with one byte width should support up to MHz data rate, but boards I've seen are only MHz or even a bit less. After three years of struggle Patil contacted Hackworth, back then in Signetics. The AGP version would then be also a bug fixing effort.
Thu Oct 02, The company announced in April that it had completed moving its headquarters to Austin, Texas. Up to 8 MB of local memory are supported and Techworks planned to release 6 and 8 MB cards, but I don't think that laguja happened.

It takes care of common rendering functions such as Gouraud shading, perspective correction ahemZ-buffering, texture map filtering well 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.
The first chip obviously did not come in expected shape. Incoming in 32 bit mode, no sign of dithering, but broken lens flares still ruin the show. Creative once again bought rights for early release, and more interestingly, they announced their Laguna3D will be compatible with CGL.
Military necessity does not admit of cruelty nor of torture to procure confessions. Then there are games partially giving up on texturing, likely because of failure in lightmap phase, those are using or originating from Quake engine, like Half Life and Thief.
That was one big nail into Laguna3D's coffin, because with advancing time game developers were using it more and more.

Inside the chips only other obvious improvement is fixed bilinear filter, which I will get to later. During the latter half of the s poor investments, slow product development and overcapacity in fabrication ventures rained havoc on the company. Thu Oct 02, 6: The CL-GD chip ought to be disappoing, because bilinear texture filter is one of the cheapest possible implemntation.
For demonstration here are screens from Shadows of the Empire:. First lowest quality, then default and finally highest. And Labuna Logic as a whole was bleeding. It will excel, of course, in Glide games like Unreal Tournament - though I can't swear how the driver set-up will be, I think it should be fine.
