Do you know if Intel plan to release for free its compiler ?

I have made a game engine based on voxel, using only the CPU and here's the benchmark I made, for 1 million voxels:

• 20 FPS for a non optimized code, using Visual Studio compiler
• 144 FPS for an optimized code, using VS compiler
• 400 FPS for an optimized code, using Intel C++ Compiler.

And I am using an i3 6100.

So yes, ICC can help me a lot for this project.

Also this program is made in C#, does ICC support C# ? ^^
