There's a new GeForce driver release available, version 397.31, which delivers optimized graphics support for BattleTech and Frostpunk. Both of those games landed on PC yesterday, and we have reviews up for each one (BattleTech here and Frostpunk here).

Beyond the game optimizations, the release notes (PDF) also mention developer support for Nvidia's RTX ray tracing technology for DirectX 12. Unfortunately this doesn't mean you can enable ray tracing in games, but it does allow developers to start messing around with DirectX ray tracing applications accelerated by RTX, provided they're running a Volta GPU. It also requires Windows 10 Redstone 4, otherwise known (unofficially) as the Spring Creators Update or April Update, which is only available to Windows Insiders at the moment.
