TBH i had never heard of this Unity stuff before you posted this. I did some light digging and as Sarge said, it's very outdated. BSG requires this? Do what you have to do to play your game i guess

After spending 9.5 years playing FFXI, i began playing FFXIV a couple weeks ago. My overclocked ATI HD 5870 can only maintain ~45 fps in many places while standing still on high settings. Complete failure at maximum lol
