I have a AMD Fusion A6-6310, and yesterday i made a driver update to 16.15.2211-160321a-301026C, and the loading of tabs are now very fast and was slow before. Thats unbelieveable.
The driver for this machine was always a little bit faulty, my first version caused sometomes system crashes. But never i have seen that a graphic dricer update make a desktop-program faster or slower. I guess there was some other bugs.
