I do not see the compute mode option anywhere in AMD Settings and I am pretty sure it's supposed to be under Gaming > Global settings.
I had the same issue with the previous 17.10.2, 17.10.3, and also both of the beta blockchain drivers from August.
The only compute drivers I've found that work in Windows 7 were from some guy in a bitcoin forum. Is installing drivers from a random 3rd party the only way to have compute mode enabled in this OS?
