Performance way too slow #28

Open danilw opened 2 years ago

danilw commented 2 years ago

I think this project spvm does not use "SIMD vector optimizations" this why performance is slow.

Maybe adding SIMD optimizations can be added to TODO of this project.

Result of this project spvm spvm_shadertoy XdlSDs.frag - 5 fps

Result of llvmpipe (CPU) - on 1280x720 resolution 160-190 fps

Yes, optimizations such as SIMD/JIT/AOT should be implemented to make it more faster, it is in the TODO list now
