What is difference between wine and wine-nine?

I didn’t know wine-nine existed before reading your thread but apparently it’s a wine fork optimized for gaming

This overlay allows you to use the latest version of wine with gallium-nine patches:
NOTE: Run winecfg and select Graphics tab: in 3D Acceleration group select Prefer native Direct3D 9.

and from

 **Why** exist **Gallium Nine** project? Because we want see happy **Linux users which can enjoy games** designed for Windows DX9 at **full resolution and details getting maximum performance, which can  hardware provide!** 

I haven’t run wine-nine and atm I don’t have any games handy to test it out

Thanks, I was just wondering, YaST didn’t really clarify in its description. I should’ve done a better search on the web.
