Ew, all this for that ? Just the default bilinear filter with prescale 2 will look better than this, if the 'pixellated only slightly softened' kind of looks was the goal. That option has been available for decades FYI, don't even need BGFX. I'll never understand the love for those 'HQx' 'xBRz' and likes family of filters, they all look hideous, heavily hurting the original art and failing to competently 'HD-ify' at the same time IMO. Welp.
