i did some investigation on leadwerks over the weekend and so far i have to say i like it. However in my opinion it is still an unfinished project but it looks promising.
One big issue is the low framerate in the current version (see samples below with GeForce GTS 8800 640 MB and CoreDuo 6600!!!).
The framerates on the beta version 2.1 are much higher so it can be expected this issue gets solved.
To build render scenes is pretty easy. The engine code is straight forward but it still lacks a lot of documentation to achieve the high standard of A7. But i was able to create a small scene with camera movement and lightning very easy.
As my summary this will be the engine (apart from A7 of course) i will do more investigation in the future.
