> If you could spec up mac, windows and linux to the same level, which platform is the most responsive?
Asking that question suggests some dedication! I don't know the answer but perhaps the following observation will be of some help, though I suppose it's pretty obvious. Notoriously, graphics drivers on Linux tend to be bad. Similarly, Linux tends to be lighter on system resources than Windows. (Mac I don't know about.) So: if your graphics hardware works well with Linux, then go Linux for Oolite; and, if your graphics hardware works poorly on Linux, choose another OS for Oolite. The Phoronix site
is run by someone who works hard to provide graphics benchmarks for Linux versus Windows.
