AMD Catalyst™ 14.2 LINUX Beta driver
Sembra che AMD, forse spinta dalle piattaforme game come Steam, stia lavorando sodo per ottimizzare i propri prodotti per Linux; le performance e la stabilità dei driver rilasciati è sempre maggiore ed a conferma di queste ipotesi sono stati rilasciati i nuovi driver beta 14.2 per Linux da AMD( Driver packaging Version 13.35.1005-14’223a-168507E).
Oltre a risolvere diversi bugfix, questa versione introduce diverse nuove features:
- Video Compression Engine (VCE) enabled for compatible GPU and APU products (e.g. GCN-based SKUs). Hardware-accelerated encode of H.264 now possible for 1080p60 content.
- Video decode (UVD) performance and efficiency improvements for the AMD R9 290/290X, R9 260X, “Kaveri” and “Kabini”
- X-Video hardware video acceleration via the GLAMOR library now supported.
- 2D acceleration via the GLAMOR library now enabled by default.
- Substantial improvements to overall video transcode times for hardware-accelerated transcoding apps.
- Tiling support now enabled on all GCN-based products.
- Substantial OpenGL feature level upgrade to v4.3.
- Major contributions to the Linux kernel 3.14 to improve dynamic power management, DisplayPort robustness and power efficiency on all GCN-based hardware.
- New programming guides and register specifications released for HD 5000, 6000, 7000 and R9/R7 Series GPUs. This will enable volunteer and professional developers to contribute to the X.ORG OSS Radeon driver, and can facilitate porting to other non-Linux platforms.
Bugfix corretti in questa release:
- [394106] : Minecraft: missing textures have been resolved
- [393609] : Resolves corruption issues seen in X-plane
Rimangono aperti invece i seguenti problemi:
