Why does a project like Docking ask for ATI work?
It doesn't have an option in it's preferences?
The same with Edges.
Edges has: Use Graphics Processing Unit (GPU) if available no in prefs.

It's not the project asking for work, it's BOINC that does so. The standard scheduler will ask for available work for GPU (Nvidia, ATI or intel_gpu) and CPU.

In the case the project does not have a GPU application, BOINC will still ask for work, because for all it knows the project could decide to release a GPU application tomorrow and then the user won't have to do anything about getting work for it. It'll be done automatically.

If well and truly left alone (aka you not doing manual Updates), the GPU work request will eventually back off until it's only done once every 24 hours.
When you see ATI work requests, then this usually means that the project already has an Nvidia application.
