You've got a very similar spec to me. I can run at medium with a bit of slowdown but runs fine at low with medium draw distance and very low AA.
Just did my best solo attempt. Second with 5 kills, unusual for me to get more than 1 kill in a round! Hid in a bush near the end and people just ran past me.
