Turn off Bloom as well in the flashpoints
My computer should be still top of the line even if it's a year old. performance wise it's a 7.7 out of 7.9 and that's pretty good rating. I also have enough memory to sustain Bloom and Conversation Depth of Field turned on without any issues. I've always had this set up ever since SWTOR came out. I've not had any issues until this latest patch. So I know for a fact that it's not those 2 things.
