Last year Ryan moved raddebugger mostly C code base off the C++ compilation - only C++ parts were interaction with d3d11 and directwrite api's. And we saw decent improvements. Here are build times in seconds.

On devmaster there was sin approx derivation with parabola yielding 2*x-x*|x| which is pretty much same formula for sin as here. On web archive: web.archive.org/web/20060619... Missing images, but here are graphs on desmos: www.desmos.com/calculator/u... with their extra formula for more precision

There's also __fastfail(FAST_FAIL_FATAL_APP_EXIT);

How about replacing sRGB/linear conversions with simple square & sqrt(x)? I'd guess that for these kind of images the difference will be very minimal, but the code will be smaller (no tables) and probably as fast. And easier to apply SIMD.
