When I worked for a game company we used the Intel compiler for a couple of versions but it caused so many issues for people with AMD we switched back to the MS compiler. In the end the performance difference wasn't enough to matter.
That's interesting: could you elaborate on those problems? I was pretty much supporing Intel on the ground that their competitors products were just running a safe path, but your input might change my view entirely.
It wouldn't be useful anymore, that was 3-4 years ago. At the time besides having AMD issues we had floating point optimization issues which messed up our physics. I doubt it's an issue today.
