- Emulating f16 with f32 is not ideal and requires a lot of value clamping - Using native data type can significantly improve performance and accuracy - With openGL, check for the compatible extensions NV_gpu_shader5 and AMD_gpu_shader_half_float - With Vulkan, enable this functionality in the deviceFeatures if applicable. (VK_KHR_shader_float16_int8 extension) - Temporarily disable hw fp16 for vulkan
