Now, now, they're only trying to help us uneducated Mac types
Maybe we need to educate them on optimization... given that compiled code can benefit from up to 30% performance increase on a mac compared to a the same hardware running Windows or Linux
(This is a test iv done btw, results will vary, but for raw calculation the default compiler produces much faster optimizations. One point in history had a PC (same PC i play elite on now) with Windows Linux and OSX running on it. Compiled and did a bench test of an application and saw the general performance to go OSX > Linux > Windows. Which surprised me since i expected linux to be the faster one. Anyway, its application specific and compiler optimization dependant. )
Graphics drivers often don't give more than a couple % -ish performance increase in general, they tend to just stop weird artifacts or glitches
