Re: Characters and non-static environment objects turn black and pixelated.

This is caused by an incompatibility issue with all AMD FX processors. There is no fix.

The workaround you mentioned is a console command. The dev console has to be enabled in the config file. There's a desciption under this video: https://www.youtube.com/watch?v=4cHF_2VmGhw

Being a Mass Effect junkie myself, I specifically bought an Intel board and processor for my newest PC. There seem to be no compatibility issues there.
