Basically tiled renderes don't like using alpha test/discard, I tried disabling this function in the FragmentShaderGenerator and found that perf more than doubled in gpu limited games! (almost all are with unbuffered rendering)

Now the key (if possible) is using Alpha Blend Mode instead, setting the value to '0' where discard should be used.
Hope it can, or this can be used as an option (hack for slow gpu).

Ps: I attached an example of typical perf boost in sgx540, also in adreno 205 I found perf increased but not that much, for example from 40 to 55 fps (with unbuffered rend as well).
