Fallout 3 Commands help. ONLY ANSWER IF U CAN REALLY HELP PLEASE.?

The console command tlb (toggle litebrite) for Fallout 3 turns off shadows and stuff so the game can run on lower end computers. but the problem i have when i use this is that the game seems to "hide" my gun... I want to be able to see my gun and play in litebrite mode. can someone help... maybe a mod that fixes this or something in the .ini file i can change...
