Anyone else not being allowed to run GPU only?

[JerWA]

When I go to my preferences on PrimeGrid it's auto selecting 3 CPU sub projects, despite me unchecking them. I've tried from 2 browsers to make sure it wasn't a Firefox/IE bug, same behavior from both.

I wanted to see the new GPU apps, but not if they're going to force me to run unrelated crap too.

Just me?

Edit: Nevermind, found a way around it in their forums. Just unchecked CPU work in the top selection.
