kiriBrinkChances are you accidentally downgraded if you didn't compare the specs of your old computer vs your new one - the old one probably is probably significantly better when comparing the GPU, CPU, etc. I find that would probably be the most significant factor, because it doesn't seem to me like the difference between Windows and OSX would be THAT big.in my experience the difference between windows and osx on the same computer (early 2012 17" macbook pro, 2.4ghz, 4gb ram, AMD Radeon HD 6770M 1024mb) is an additional 20~ avg fps and much faster loading times on windows. it's enough to make me only play it on windows (also i don't feel like downloading steampipe twice) but not sure it would be worth spending the £70 or so on a copy of windows just for that.
maybe the fps increase is more pronounced if you use a config or something, idk. i've never tried that.
Whoa hey now, I never said anything about paying for windows. But i'm not saying anything about pirating. I'll just say that getting a copy of windows isn't that hard.
For myself, and almost a dozen other people I've converted into bootcamp users, the fps increase is usually double or more. This includes tweaking the windows system for performance, and yes using configs and various settings.
