Nuovi driver Catalyst 13.8 beta per le schede Radeon, ora con frame pacing

AMD ha reso disponibile la versione 13.8 beta dei propri driver Catalyst, compatibili con le schede video della famiglia Radeon dalla serie HD 5000 sino alla più recente HD 7000, disponibili in versioni a 32bit e a 64bit per sistemi operativi Windows 7 e Windows 8. La particolarità di questi driver risiede nell'abilitare per la prima volta il supporto alle tecniche di frame pacing, grazie alle quali viene ottimizzato il funzionamento delle configurazioni CrossFire evitando per quanto possibile l'insorgenza del fenomeno del microstutter.

A questo indirizzo abbiamo pubblicato una analisi prestazionale della scheda Radeon HD 7990, modello top di gamma dotato di due GPU montate sullo stesso PCB, mettendo a confronto le prestazioni ottenibili con questi nuovi driver abilitando e disabilitando la funzionalità di frame pacing direttamente dall'apposita voce presente nel pannello Catalyst Control Center.

I driver sono disponibili per il download in locale a questa pagina. Di seguito le principali note fornite a corredo.
