With today's pre-order launch, I was curious to see whether they would comment on restoring Linux (and OS X) support, but they have not. Oculus suspended Linux and OS X support last year in order to focus on their Windows support with no timeline for when they planned to come back to providing Linux support. However, now that everything is ready to go, they apparently aren't yet ready to jump back into the VR scene for Linux gamers. There's also nothing new with regards to Linux via the Oculus developer area.
The recommended system requirements for the consumer version of Oculus Rift continue to be Windows 7 SP1 or newer, a NVIDIA GeForce GTX 970 or AMD Radeon R9 290, 8+ GB of RAM, and a Core i5 4590 or faster.
