Black textures

First let me say thank you Keen Software house for making an incredible game, but unfortunately after playing for 300+ hours with out this problem...well this is a huge problem that keeps me from wanting to play any more because i spent countless hours trying to alter the cfg code to see if i could resolve this problem but nothing works. I'm aware that my current laptop is way below recommend specifications BUT i was running this game smoothly on low -med settings before this texture rendering issue occurred. When in-game during the day i can see everything, even the black torus around the planet, but when inside a cockpit or a ship if there is no lights everything turns pitch black. light used to make its way into these spaces before but now im forced to only play during the day. the blocks used to just get dark but not completely blackened out

also sometimes when i load back into my world everything some times turns black, textures, blocks, everything but the sky. please help me I really really love this game and it surprising helps keep my severe Depession at bay when i get lost in Space engineers.
