That project still has yet to release an actual consumer-oriented usable product, and their graphics engine is basically something that's barely capable of low-speed OpenGL 1.x. Calling that an "alternative" to any product offered in the last 10 years (literally, one decade) from the likes the AMD, NVIDIA, Intel, or so on is just silly. You might as well call "begging for a cure from God" to be an alternative to a routine appendectomy for someone dieing from appendicitis.
You might be able to accelerate RENDER on that hardware (if it exists as anything other than a ridiculously expensive FPGA board), but then RENDER is an 11 year old spec that predates the release of programmable GPUs, which are pretty much mandatory for any modern acceleration (even on basic 2D desktops). If all you have is a basic triangle rasterizer you might as well just dump the hardware acceleration entity and do everything in software on the CPU's SIMD engine; you'd get better performance.
