Even though I know this message will never reach the list, I figure I should respond anyway. Just because a chipset claims to offer 3D support, doesn't mean it actually does. If there is even a complete OpenGL ICD for this chipset under Windows (which I seriously doubt), I would bet that most functions were simply being done in software emulation. This is why most video cards can't do things like run even the original Quake game in OpenGL mode. Or run a CAD application. The only portable chipsets capable of such things are the very recent GeForce2Go, GeForce4Go, Mobile Radeon, and Mobile Radeon 7500. The old Mobile Savage chipsets were halfway decent, as I recall, but they never achieved any significant market penetration. Drawing a "hardware accelerated" 3D line (which is likely all you're going to get) isn't going to be much faster than just rendering it with Mesa. A good example is the Trident CyberBlade I7 chipset that was used in the old I-Opener internet appliances. "The World's First 3D Graphics Chip Integrating Core Logic For The Sub-$1000 Notebook Market," the press releases said. How impressive! Except it's not really a 3D chipset. It has a terribly incomplete OpenGL ICD, no hardware acceleration, and really can't run diddly squat in the way of OpenGL anything. It's a 2D chipset, but you can't call it that, because everyone wants 3D chipsets. So they call it a 3D chipset. What it comes down to is if it's not a modern Nvidia or ATI chipset, it's not going to do 3D. That means GeForce or Radeon in the name (although the ATI Mobile Rage 128 might be tolerable). Mesa is your friend, otherwise. --Vito -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org Please, *PLEASE* don't subscribe through a forward/expander/false domain
