I don’t have the level of experience with BGFX that @glh3586 and others here have, but I’m concerned by the prospect - using it may well lock us out of accessing lower-level API features, which is a substantial downside. It’s not that terribly hard to design and implement usable abstractions over lower-level APIs - I’ve done them before. It’s certainly not a cakewalk, but it’s not prohibitively difficult either. As @oxplay2 mentioned in another thread, there’s the additional downside of relying on another dependency in addition to LWJGL, which adds about 4x more ways for jME to be negatively impacted by another project dropping or lagging support. I believe jME would be far better served moving forward by keeping our rendering in-house rather than outsourcing to another project.
