Kevin Schmitt benchmarks Adobe’s After Effects CS4 on Leopard and Vista. The results are ugly:
Cripes, the Mac OS X version of After Effects is absolutely smoked again, and the results are slightly worse than last time in places. Either Adobe isn’t tuning After Effects on the Mac at all, or tuning the buhjeezus out of the Windows versions. Hell, even single process rendering on Vista generally spanks multiple processes on Leopard, for the love of Pete.
