optimised darts textures and max sizes. we were shipping the radiation dart at 4k on all textures.
RadiationDart_AO 4096 -> 512
RadiationDart_bc 4096 -> 1024
RadiationDart_mg 4096 -> 1024
RadiationDart_nrm 4096 -> 1024
42.7 MB → 2.17 MB VRAM
looking at other textures that are unnecessarily big too to optimise where applicable.
