It supprises me you have to play with so low settings, everything except you're graphic card is fully capable of handling the game - And the graphic card ain't that bad either. Anyway, I don't think you should care so much about 'AA' and 'Bloom' since I run the game without both of them and I think I'm using something called 'HDR' insted of 'AA' and the graphics is sweet no matter if I'm fighting 15 people while spraying around with spells... Bloom effects made my graphic pretty nasty since it get's so bright, the stone walls reflect light like a bronze plate and it's really no use from what I've experianced...
But what happens if you try to set up the detail but have the same resolution, since you should be able to run higher...
