Hi Riccardo,
The framerate of the game was reported by the main Windows dev to be
significantly higher with a clang build than with a gcc build. I'm not
sure about Linux.
I thought I'd try that out on Debian. Using current (from the
respective git repositories this morning) gnustep and oolite code, I
built with gcc and with clang.
On my system in the tutorial the gcc version was reporting a frame rate
in the 70s. Unfortunately, the clang version crashed after displaying
the startup screen, with an assertion checking that an object was a ship:
