In the benchmark on their site, they compare VectorC to Metroworks & Intel’s
reference compiler, but Visual C++ is missing in that list. Maybe because
Visual C++ allready performs quite well as far as optimization is concerned?
This ‘at least 100%’ (or 1000% ???), can you back that with specific
benchmarks (that include Visual C++).

I heard it was at least 1000%

I’m currenlty re-doing the company website that has Visual C++ benchmarks,
but, on this Athlon 1GHz I’m using, vectorC gets on average 50% better
performance compared to Visual C++ (the new benchmarks has a whole myriad of
tests). I’m yet to test it properly on other processors, but on Intel
systems, it gets a helluva lot better than that…

The new site (with more comprehensive benchmarks) should be online by the
end of the day.

I mean twice as fast, or 100%…–

No, 100% faster means that it takes 100% less time to run, thus finishes
instantly. Since VectorC is guaranteed to be > 1000% faster, it means
it completes at least a fortnight before it starts!
(To answer the original poster: I know of nobody who has built SDL with
vectorC, so go ahead; maybe you uncover some SDL bugs in the process.
But if you post such outrageous statements like “at least 100% faster”,
be certain that we will attempt to do worse!

Actually, no. If I said it cuts execution times by 100%, then es, that would
mean that it executes with 0 time, but 100% faster means it runs at twice
the speed (or 50% execution time).

It also helps finds bugs in the compiler itself (as well as a few in SDL…
damned non-ANSI code)
