Hi OwenBrooks - thanks for your reply. I note you state you get 80-100+ fps I assume you are playing with VSYNC=OFF. I don't have any stuttering with VSYNC=OFF, only when it is ON (as I like to have it on) and I'm around other players do I get the stuttering.
Interesting, what is the reasoning for you having vsync on with your system specs when you encounter stuttering with it on ? some games are better with vsync on but i find vsynch off for Swtor is best.
Are you getting screen tearing or playing on a tv ?
If you really want to have vsync enabled you will need to enforce triple buffering or you will get performance issues.
You will need to install something like riva tuner to ensure triple buffering is enforced though.
