With the Xbox One now being based on an x86 architecture, and the operating system sounding suspiciously similar to Windows 8, it should be very easy to port games to Windows 8.1.

NVIDIA Launches GeForce Experience 3.0

by Scott Michaud |
It's been in Beta for a while, but NVIDIA has just officially launched their new GeForce Experience application.

What's Asynchronous Compute? 3DMark Time Spy Controversy

by Scott Michaud |
A game developer will tend to avoid a performance-reducing feature on certain GPUs.
This is a trivial example, because I believe every Vulkan- or DirectX 12-supporting GPU can do it, even the mobile ones.
