Palletized Textures on G400

[deKerf]

Hey all, just wondering if anyone knew if the G400 supports palletized textures in games. I'm assuming it does (hell it supports everything else under the sun). This is a feature that 3dfx has done well since the start but nVidia has just started supporting with the Geforce and they haven't even revealed it to dev'ers from within their driver yet.

-Thanks

It's supposed to support it, but it is not on offer in the latest PD 5.30 drivers.
Here's what DXCapsViewer has to say for my G400 MAX :-

Texture Formats
16 bit 565 RGB
16 bit 4444 RGB ALPHAPIXELS
16 bit 1555 RGB ALPHAPIXELS
16 bit 555 RGB
32 bit 8888 RGB ALPHAPIXELS
32 bit 888 RGB
16 bit 565 BUMPLUMINANCE BUMPDUDV
16 bit 88 BUMPDUDV
16 bit 88 LUMINANCE ALPHAPIXELS
YUY2 FOURCC
UYVY FOURCC

There is a lack of PAL4 and PAL8 there.
Also, the current drivers don't seem to support Anisotropy filtering, which the G400 is spec'd to support.
Reminds me of the release of the G200, and the months we had to wait for SubPixel support to be added to the drivers.

It's the usual story [and this is _not_ just Matrox]: release the hardware, then sort out the drivers. Maybe 6 months after the hardware is out will the drivers be feature-complete. First they have to concentrate on the "important" things: making sure their card is the fastest in all the reviews, by optimising the necessary bits of the drivers. Then they will fill in the missing bits. sigh.

Lewpy:
The G400 doesn´t properly support anisotropic filtering. It only supports minimizing filters, not maximizing (or something like that). But guess what? No video card out there supports anisotropic filtering (at least in the way it is supposed to be). It takes A LOT of processing power to perform anisotropic. Maybe when fillrates are around 1 Gigapixel+ we will see anisotropic filtering.

So you should take all the video card marketing stuff with a grain of salt. G400 doesn´t support anisotropic? Well, partially it does. Even worse are the TNT´s. You know what 4-tap anisotropic filtering is? Sounds imporessive in TNT´s spec sheet doesn´t it? Well, it´s only the old bilinear filtering. But let´s see, how could tnt support anisotropic if it doesn´t even do trilinear?
