Hey all. I have an ATI Radeon HD 4870 512 MB on an Early 2008 Mac Pro running 10.7.5. I ran into issues playing Walking Dead Season two and it looks like I need to update the drivers for the Radeon. However it doesn't seem like I can do that without either upgrading to Mountain Lion or Mavericks. I don't really want to do that because I don't want to either slow down my mac or affect the performance of my Adobe CS6 suite. Is there a way to upgrade the drivers without changing system?

I did try an experiment. I created a partition and put Mavericks on that. When I did that the game runs fine. So it's definitely the drivers.

Is there a way to install either Mountain Lion or Mavericks drivers for my card into Lion?

Thanks
