3Dlabs sent our test lab the Wildcat II Elsa Gloria III - Performance Push From 12th Generation Drivers · Synthetic Benchmarks With. 3Dlabs Wildcat II - Driver, Continued. Calibrating the color is a snap in this tab. Since the Ramdac offers 10 bit resolution per color. On February 24th , 3DLABS refocused its business and stopped developing its workstation graphics cards for the PC. 3DLABS now trades as ZiiLABS Missing: Compatible.

3Dlabs Compatible Driver Driver
Triangle setup engine claims MFLOPS just like Delta, but unless it has separate clock domain it had to be redesigned for halved per clock performance. Graphics pipeline itself is a mere evolution of first Permedia, 3Dlabs Compatible Driver using 3d units as superset of 2d functions. Host accessible is also output FIFO 32 bits wide. Smooth vertex shading in 16 bit color depth requires manually enabled "free" dithering.

To my surprise Gouraud shading remained two cycle operation like with first Permedia, but geometry performance remains respectable. Subpixel precision can be selectively 3Dlabs Compatible Driver per polygon or even disabled to speed up rendering. Texture address unit also properly handles perspective correction, however there is an option for less accurate division to avoid speed impact. In any case the correction is faster and more precise than with first Permedia.
Addresses are then passed to texture read unit for fetching needed texels. 3Dlabs Compatible Driver unit is backed by cache sufficiently speeding up bilinear and even trilinear filtering, but mip mapping can still be more costly. Four texture formats of 15 and 16 bit RGB A are supported, true color textures were for 3Dlabs Compatible Driver reason disabled. Additional LUT formats are available for 2d rendering as well. Fog unit applies linear interpolation per vertex with value calculated by host function and can reject completely fogged fragments from plotting.
Blending unit supports various logical functions, unfortunately additive texture blending needed in many advanced games is still unavailable. Newly implemented optimization can skip frame buffer reads of pixels covered by texel with alpha value of one. In the end dithering can adjust colors into final format and I did not always like what this stage does. Memory controller looks the same, but buffers in local memory now do not have to 3Dlabs Compatible Driver allocated continously.
Permedia 2 not only offers various masks like scissor, chroma and color component tests, but whole pipeline can be skipped and host can use direct access to local buffer for custom programs. Texture colors in X often show excessive banding and dithering would only add annoying pattern to the mess.
Specification says fillrate is halved when Z-buffering is used, but I checked it and doubt Z-buffer is the culprit here. In fact depth buffering can improve performance as one would expect from pipeline rejecting pixels failing hidden surface tests. There is no way 3Dlabs Compatible Driver buffering would eat half 3Dlabs Compatible Driver memory bandwidth so what is the reason why Permedia stays behind the expected performance of highly parallel architecture?
While it should have allowed single cycle 3d pixel performance I could not get significantly above results of two cycle-like speed no matter how many features were disabled, Gouraud shading included.

This riddle remains to be solved. Most gamers at the time opted to upgrade to a PCI Pentium system instead.
The 3D Blaster VLB nowadays is a very rare card and usually if it shows up on auction websites, the price will be very high. However, the memory upgrade module is more difficult to find than the 3D Blaster VLB itself, and would also be very steeply-priced. Display drivers are available for Windows 3. 3Dlabs Compatible Driver
Permedia NT differs from the original in that it features a separate geometry co-processor chip known as Delta for performing geometry setup calculations. However, the Delta 3Dlabs Compatible Driver co-processor is optimized for professional 3D and CAD applications rather than for games, resulting in anemic overall gaming performance.

On the upside, the main advantage at the time was that 3DLabs was the only company producing consumer-level graphics chips that had full OpenGL ICD driver support other manufacturers didn't support OpenGL at all or released a miniport driver instead. The discrete Delta geometry co-processor chip originally featured in the Permedia NT is 3Dlabs Compatible Driver integrated into the Permedia 2's core logic, resulting 3Dlabs Compatible Driver a single-chip solution.
Permedia 2 supports AGP texturing as well as 3D rendering in bit color depth. Major image quality degradation is caused by the lame bilinear filter.
Well, such was the impression from driver the 3dlabs support page still 3Dlabs Compatible Driver to use. But then I tried driverdespite it offering only Permedia 2 strings and what do you know, it works. With its own quirks, it seems old Permedia was no longer paid attention to since second one came out.
