> Intel Gen doesn't support denormalized floats and gradual underflow (and I think other GPUs are similar here) It differs from vendor to vendor. I know at least one major GPU vendor that has full denormal support, at least for normal arithmetic (not sure about transcendentals etc). In Vulkan, it's possible to ask the GPU to either always flush denormals to zero, or (if the HW supports it) to never do so, but I think nobody uses this, and there may be a (huge) performance penalty from requesting either of these!
