there are not that many people having issues with AMD drivers. on every forum, it is only a few.. out of how many people running AMD GPUs in the world? After taking in to account all the different hardware configurations out there, which is impossible for ANY manufacture to test, there aren't any real issues at all outside the normal for any manufacture.. be it AMD,Nvida, Intel, etc. Heck Nvidia had to release a hotfix driver just this week to fix some issues..
Add in the issues that are caused by the user, or something they have running on their PC (antivirus, add on software like display fusion, etc, which can cause issues) etc.. the issues are nearly non existent. The only change I have noticed is GPU temps, but they are still within the GPU spec, so it really isn't an issue over all, and it isn't the first time temps have been effected by drivers, it happens to Nvidia as well as AMD. Heck even I have ran into issues in the past, and in the end, guess where the problem ends up being 99% of the time... it was the interface between the chair and the keyboard the caused it aka me, or something I did, or some utility I decided to use, but very seldom does it turn out to be the actual driver, or piece of hardware that is the cause.
As for the administration that is leaving AMD, it has already been stated that those that left have ZERO to do with the driver department.
So, yea.. about that negativity.
