Are there software 3D engines with GPU acceleration?

Question

GPGPU

Purely software graphics, implemented entirely by the CPU / FPU, imposes significant performance restrictions. Full-fledged hardware 3D often (this is my experience from the time of the birth of this business to this day) sins hardware and drivers with specific visual glitches (from "artifacts" to the complete insanity of some combinations) and other problems (for example, the lack of support for windowed mode in many games) . Why not make an intermediate option - software rendering using GPU computing resources? To my surprise, I could not find any attempts to implement this idea.

Answer 1

Possibly Unity3D. It supports writing a game for any platform. Perhaps it has these functions on this topic, but if you write for Android, then install the Android SDK, JDK, since neither one nor the other comes with Unity.

Answer 2

Do you want to take a forward render from OpenGL 1.1 + read lightmaps on the GPU? Or how? Most likely this option was before OpenGL 2.0. And when geometric shaders 3.0 also came, they forgot about it altogether and removed it to depricate. We decided that it is better to pay more to the renderers for bugs, but the picture will be better.
