Hi, BillyGoat. Thanks for the feedback. The pixelart filter is not a filter in a sense that a filter comes at the cost of CPU and memory. It is a resolution trick. The issue your seeing is that the rain is a particle system and there are a lot of polygons loaded all at once from all the buildings. Unfortunate I cannot adjust the amount of rain particles because that is essentially one of the enemies of the game. I also have the camera draw distance already quite low. I'm afraid it may be too intense for your current hardware.
