I'm also having this issue as of the last few days. Was able to pvp normally in the morning, then tried in the pm only to get 2-7 fps in all matches. It was unplayable. Maybe they just need to take the servers down for maintenance...

I too am having this issue since the patch. I had no issues with this prior. I've tweaked and updated the graphics card drivers and the results have not changed. As a ranged class I can manage to get a few medals, but melee is unplayable. This has to be an issue on Bioware's end... Playing on Prophecy of Five
