xBR vs HQx Interpolation Filter Comparison. UPDATE: the comparisons in this post aren't a true representation of hq2x (more info in this post). It's also mentioned in the FSF Free Software Directory and in Wikipedia. Other interesting effects are HQx and xBR. These effects are a bit slower than Scale2x, . The HQX filters, namely hq2x, hq3x and hq4x, are well-known pixel art scalers. They are mainly used by old console (such as NES) emulators.
i found out about this filter from some emulators i have. is there anyway to add it to this game? its just that the sprites are kinda low resolution. You can reduce the instruction count by using vector operations: e.g. instead of edr = bool4((w1.x < w2.x) && ir_lv1.x, (w1.y < w2.y) && ir_lv1.y. Hi i was wondering if it was possible to add these kind of filters i think it would be useful and interesting for image tr.
