AMD reports 79% reduction in driver overhead on the CPU using #Vulkan versus OpenGL|ES on Mali architecture
-
@warrenm Perhaps Metal will still be worthwhile as it's designed for TBDR (I did wonder about that - it makes a mac version tough)
@_psonice Perhaps even more importantly, it will continue to provide a higher-level interface language-wise (Obj-C vs C)

@mnstrmnch@warrenm Btw, either of you know a way to query actual memory usage for GL ES textures on iOS? -
@_psonice Is it not possible to infer from the dimensions and pixel format? -
@warrenm yeah, that's what I'm doing, but I suspect in some cases I ask for an R image and it uses RGBA internally (4x more memory) -
@warrenm it's hard to tell for sure, but I have a serious memory issue on the 4S so I'd like to know.
