If it matters, it is not supported in Nvidia GT 520 (Forceware versions 280.26 & 331.82)

tnt supported them with early 3.xx series drivers in direct 3d
pretty sure some geforces supported them because i rememeber in the game enemy engaged comanche vs hokum doing something to force palleted textures not to be used

This thread is strictly about native support of this OpenGL extension. Native support = less VRAM usage, etc. Can't just simply lay 'it supports palettes' blanket responses to this.

The Trident Video Accelerator Blade 3D/ProMedia (8 MB) integrated into the VIA PLE133 chipset supports it, atleast as per AIDA's report. However the driver loaded is that of default bundled with Win XP (OpenGL DLL version 5.1.2600.5512)

Sorry if this isn't what you want, as i don't know how to actually verify the 'native support' though it might be reported as supported.

Download opengl extensions viewer and check database of their results integrated in sw. They have plenty of cards in there...But xp only - http://www.realtech-vr.com/glview/index.html

From cards i tested and archived results these support it:
3Dlabs PERMEDIA, Oxygen GMX, PERMEDIA2, Oxygen GVX1, (Oxygen VX1 has no support)
