Not sure whether I should come here or to the linux amdgpu developers for this one?
With both the current simcity and simcity 4 games there is an issue where the lighting is not correct after having switched from the AMD drivers to the AMDGPU open source drivers on my linux host where the Win7 Pro VM resides. The screenshots attached probably provide a better explanation than I can write for this one. I had not issues with the previous versions of the ati-drivers versions 15.12, 15.9, etc.
My host is running kernel 4.9.33 and Workstation 12.5.7.
I'm going to give a newer kernel a try first from the 4.11 or 4.12 branch and see what happens soon as I get some free time in the next few days before posting to the amdgpu maintainers about this. I'll post an update after trying the other kernels to keep you in the loop.
Just updating where I am.. I have tried 4.9.36 without any luck as well as the updated mesa gentoo package. I can't get 4.11.9 to work as vmware-modconfig crashes for someone unknown reason.
I've posted into the gentoo forums if you want to follow along.
