InsideHW: "When do you stop developing drivers for the older cards? Are newer driver versions that still support older models, but are actually the same as previous ones, meaning that you stopped improving them"?
Terry Makedon: "We stop developing when we see that sales have slowed down a lot AND we feel that the code is very stable, and that there are no more bugs being reported on those products. Right now, our older products (pre R600) get quarterly Catalyst updates while the newer products get monthly updates. There are simply not that many bugs to fix anymore and all the optimizations have been squeezed out of the cards."
