The higher I go the better it looks. I discovered this makes vanilla scanlines look better too. But unfortunately even if I leave shadow_mask blank or set alpha to 0, it still has the performance hit. Maybe the performance hit is all from the prescale not the blending? It would be nice to save rendering cycles blending an invisble shadow mask.
