FiringSquad heeft nu ook een review van deze professionele videokaart gebouwd. Er zit dus een Permedia3 chippie op, en is bedoeld voor grafische workstations. Voor gamers dus niet zo interessant, ook omdat ze $999 moet kosten.
Hier heb je een stukkie over de 'Virtual Texturing' feature van de kaart.
Virtual Textures is a technology that the Oxygen GVX1 utilizes to essentially provide more texture memory. Although the Oxygen GVX1 already has 32MB of texture memory, which seems like a good deal for a gaming card, remember that we are dealing with a high-end piece of work here, and 32MB is not enough. Virtual textures allows the card to use its onboard texture memory as a cache for textures that are actually stored in the system memory. Since a high-end graphics workstation (or any machine, for that matter) could easily have 1GB of RAM or more, we have many more textures stored.
Thus, the textures are stored in their entirety in the system memory. When a certain texture is needed, then, it is retrieved from the system memory. However, the whole texture is not retrieved. Instead, the GLINT R3 chipset determines how much of the texture is needed based on what the scene that is being rendered looks like. If the entire texture is not visible in the scene, then the GLINT R3 will break up the whole texture and use only the parts that are needed.
