forse non avete capito bene l'importanza di questa nuova versione del driver RadeonHD:
VRAM buffer paging;
Partial Radeon HD 7000 series (Southern Islands chipsets) graphics acceleration; and
[url]The RadeonHD_RM.resource is enabled for outside use (i.e., enabled for 3D driver use).[/url]
il driver è pronto per un uso 3D !!!
[url]In short, this version is ready for 3D drivers.[/url] This almost brings the driver up to what was planned for version 1. I say almost, because compositing support for Radeon HD 7000 series cards is still missing.
inoltre ha una sorta di memoria virtuale (VRAM Buffer Paging) ossia quando la ram della scheda grafica si esaurisce 'swappa' sulla ram fisica del computer !!!
VRAM buffer paging is a feature that allows more VRAM to be allocated than physically exists. When this happens, the driver will store the least used buffers in RAM, and intelligently page buffers into VRAM when the graphics card needs them. Buffers can be textures, shaders, vertex buffers, or other data that the graphics card uses. You can think of it as a form of virtual memory for graphics cards. It allows the system to continue to work even when there isn't enough physical VRAM available for demands, albeit with reduced performance (copying to/from VRAM takes time away from other tasks).
qui c'e' un video che fa utilizzo di questa feature:

http://www.youtube.com/watch?v=0i07gnux ... e=youtu.beThe 3D scene in this test/demo contains round 100,000 triangles, of which up to 50,000 or so can be visible on-screen at any one time. However, it renders the entire scene 4 times; once for ambient lighting, and once for each light (not the most efficient method, but it works). So, it's actually rendering up to 200,000 triangles per frame. That is far beyond anything that any Warp3D program has ever achieved.
