Wine Is Not an Emulator
But, yes, CrossOver is effectively a commercially branded fork of Wine with additional patches for compatibility and configuration.
As for Wine, it's a suite of binaries and libraries designed to run Windows executables as near-native as possible outside of Windows proper. Think of it as a pile of reverse-engineered Windows DLLs coded to run on top of your native operating system. The graphics drivers generally suck, and that's why 3D performance sometimes tanks or just breaks. If an app is just CPU-bound or not graphics-heavy, though, it should perform quite well under Wine. Traditional productivity/office apps work very well under Wine (MS Office and Corel Office were early drivers for Wine compatibility in the 90s), but some modern 3D games manage to work fine under Wine too.
