Have any one investigated into this one?

Its open Source, it seems a lot of games uses the engine. Its written in C++

And no, I can't do anything about myself, lack the skills and the HW.. :(

Downloaded, and in directory base/springcontent/ present directory "shaders" :) in which 2 dirs : ARB and GLSL , with tons of files inside.

What mean that even if it possible to compile engine, and somehow (easy or not easy) disable shaders, its still will a bit suck, because as i see on images from the games which use that engine, all the graphics pretty modern and for sure shaders are here as well.

In other words : gallium/mesa and then.

The engine looks pretty advanced and good. Would be cool to have something like that in the future.

That is a shame, but I kinda guessed that it would be difficult.

what about this one then??
