AMD ha reso disponibile il primo set di driver Catalyst 14.1 beta, la prima ad implementare le ormai famose API Mantle che consentirebbero aumentare le performance rispetto le directX.
Il primo titolo ad esssere già compatibile è Battlefield 4 che grazie ad una patch rilasciata recentemente implementa tale supporto.
I driver sono disponibili per sistemi operativi Windows 7, Windows 8 e Windows 8.1 in versione a 32bit e a 64bit, compatibili con le schede video a partire dalla famiglia Radeon HD 5000, la compatibilità è garantita anche con le nuove APU AMD.
Ecco le note di rilascia di questa release di driver:

Known Issues
- Mantle performance for the AMD Radeon™ HD 7000/HD 8000 Series GPUs and AMD Radeon™ R9 280X and R9 270X GPUs will be optimized for BattleField 4™ in future AMD Catalyst™ releases. These products will see limited gains in BattleField 4™ and AMD is currently investigating optimizations for them.
- Multi-GPU support under DirectX® and Mantle will be added to StarSwarm in a future application patch
- Intermittent stuttering or stability issues may occur when utilizing Mantle with AMD CrossFire™ technology in BattleField 4™ – AMD recommends using the DirectX code path when playing Battlefield 4 with multiple GPUs. A future AMD Catalyst release will resolve these issues
- Notebooks based on AMD Enduro or PowerXpress™ technologies are currently not supported by the Mantle codepath in Battlefield 4™
- AMD Eyefinity configurations utilizing portrait display orientations are currently not supported by the Mantle codepath in Battlefield 4™
- AMD Eyefinity technology is not currently supported in the Star Swarm? application
- AMD testing for the AMD Catalyst™ 14.1 Beta Mantle driver has been concentrated on the following products: AMD Radeon™ R9 290X, R9 290, R9 280, R9 270, R7 260X, R7 260, HD 7000 Series, HD 8000 Series, A10-7850K and A10-7700K. Future AMD Catalyst™ releases will include full test coverage for all AMD products supported by Mantle.
- Graphics hardware in the AMD A10-7850K and A10-7700K may override the presence of a discrete GPU under the Mantle code path in Battlefield 4™
- Frame Pacing for Dual Graphics and non-XDMA configurations above 2560×1600 do not currently work with Battlefield 3 and Battlefield 4. An upcoming release will enable support
- DX9 Dual graphics is not supported in AMD Catalyst 14.1 Beta. An upcoming release will enable support
