Then wait til it's released. It's a couple of parsecs away from "everything at high standards" just yet.
Or just consider 20 bucks for 3 months an investment in making DU the "most important MMO" of the decade and if your rig lets you play, bonus!
I'd suggest that DU is not currently scaled for millions of players. They've a bit of work before it will scale that far. Currently it's handling the load via dirty hacks.
