My Fallout New vegas is getting glitchy with no sound coming from my gun, exclamation marks everywhere, cannot pause to my main menu, random textures appearing on my gun and my armor. Im using Fallout_fullscreen from Nexus mod manager, ArchiveInvalidation Invalidated on, 214 mods loaded and have all dlcs.
if theres anyone out there can you help me fix my game

How about removing all mods and adding them back one per time to find the one causing glitches?
