AROS: Nouveau-Grafiktreiber 5.30
Für AROS liegt nun eine neue Version des 2D/3D-Treibers Nouveau vor. Das Hauptaugenmerk des Updates liegt dabei auf einer Leistungssteigerung bei den 2D-Operationen.
Die Version 5.30 wird Bestandteil der nächsten Nightly-Builds des Betriebssystems sein und kann alternativ auch unter dem Titellink heruntergeladen werden.
Changes:
- 2D driver alpha blended operations (WritePixelArrayAlpha) using 3D hardware acceleration on all families of nVidia cards. GeForce 1-4 family cards use fixed function registers, newer family cards use programmable shaders. This is first AROS driver that uses 3D rendering for 2D blending operations. Reported tests show increase from 20 MB/s -> 800 MB/s for PCI-E cards
- Performance improvements to font rendering - using 3D hardware acceleration for anti-aliased font rendering
- Performance improvements to compositing - measurable at about 10% increase in FPS output
- Fixed problem with jittered output for high frame rate applications
- Updated sources to 2011-03-19 nouveau driver
- Allowing smaller (32x32) RAM->VRAM transfers to go via GART as well - 2 x performance improvement for such transfers
