This has nothing to do with AE's GPU settings. E3D uses its own routines. The rest you just have to figure out. there's no general recipe here and you have not provided any useful info about your system, version of AE, driver versions etc, anyway, so nobody can even guess which knobs to turn and which levers to push.
Raytrace uses CUDA GPU, in fact it has always worked. Now it stopped working and I tried it on several computers.
I don't see any answers yet for you. Did you find a solution yet? If so, what helped you?
Kevin I feel bad for you. You have the worst job here, going around on every forum post asking if people find their solution yet. I hope you get a promotion soon buddy. =)
