NVIDIA GameWorks is a collection of technologies for "providing a more interactive and cinematic game experience and thus enabling next gen gaming for current games." GameWorks consists of NVIDIA's PhysX, VisualFX, FlameWorks, PhysX FleX, and other upcoming technologies to empower PC gaming on NVIDIA hardware.
It's been known for several months now that NVIDIA GameWorks would be coming to Linux, but with the recent talk about it, I've been able to confirm from some NVIDIA sources that the Linux version of it should be available "before the summer." In H2'2014 sounds like when we'll see native Linux games employing NVIDIA's tech. GameWorks is also expected for Android too, which makes sense given the immense power of the Tegra K1 SoC with Kepler graphics.
It will be nice to see PhysX on the GPU and NVIDIA's other gaming tech for Linux. While it's NVIDIA-only and will be limited to using their binary driver, NVIDIA's binary Linux graphics driver remains the preferred recommendation by NVIDIA Linux game developers. The AMD Catalyst driver is still buggy when it comes to many OpenGL games, the Radeon Gallium3D driver is becoming in a decent state but still not trouble-free, and the Nouveau driver is in a piss poor state due to its lack of reclocking. For more on the state of Linux graphics and gaming, see our hundreds of display driver articles and Linux graphics card reviews.
