I was having this problem with Dragonball Xenoverse, I turned off FXAA and it started working fine. I was a repeatable error at a particular part of my game. What is happening is the game is calling on something that doesn't exsist, so the mods them selves may not be complete or glitchy/buggy or it could be they are not made to work with certain settings. The mods may also be corrupt or the base game could have had some corrupted files, tends to be with the .dll files, if it is steam you and try to verify the game cache integrity.
