Already running the Windows 8.1 Preview? Thinking of installing it? Either way, you're in luck: both AMD and Nvidia have posted graphics drivers tuned for the new OS update.
AMD's Catalyst drivers for the Windows 8.1 Preview are available from this page. They feature WDDN 1.3 support for Trinity, Richland, Kabini, and Temash APUs; Radeon HD 7000-series and newer GPUs; and a bunch of newer FirePro cards. Supported Windows 8.1 features include, in the company's words:
- Wireless Display – Microsoft’s support for Wireless Display Technology
- 48 Hz Dynamic Refresh rates for Video Playback
- Aggressive V-sync interrupt optimization
- Skype/Lync video conferencing acceleration
- New DX11.1 feature – Tiled Resources
Nvidia, meanwhile, says you can grab its Windows 8.1 Preview drivers straight from Windows Update after you install the new OS. The company has put up a blog post here about the drivers, but it doesn't say much—just some boasting about its driver development efforts and its collaboration with Microsoft.
