"If an exchange between two parties is voluntary, it will not take place
unless both believe they will benefit from it. Most economic fallacies
derive from the neglect of this simple insight, from the tendency to assume
that there is a fixed pie, that one party can gain only at the expense of

MetaBalls demo updated
Wednesday, October 19, 2005 | Permalink

I just recently got myself a new dual-core Athlon64 3800+, so naturally I had to try taking advantage of this extra processing power. Most of my demos are more GPU limited than CPU though, but MetaBalls is an exception to that rule. So I implemented threading into it to improve performance. Everything couldn't be parallelized though, so the gain is fairly moderate, about 15-20%. Another reason for the moderate increase is that the bottleneck apparently shifted from computations to cache/memory. The gain is larger when running the slower FPU path than the 3DNow path, about 25%.
This CPU also supports SSE3, so naturally I threw in an SSE3 path as well. 3DNow is still a tiny bit faster though.
