Currently, for desktop (with steam support) we have:
* C2 R216 (and previous) with :
- NW10.5 with official experimental greenworks plugin v0.3 (small project old version of NW)
- NW11.x with official experimental greenworks plugin v0.4 (with jank and vsync issue)
- NW12.0 (better than 10.5 and 11.x but memory issue for big project after few hours of game) no official plugin for steam support (but I own an unofficial plugin functionnal)
* C2 R219beta with NW13-alpha but the 1st beta was release since 2 or 3 days and a plugin will be release or create after the final release of nw13 (or as soon as the V8 engine will be stable)
