Hi, sorry for the offlist reply, I didn't notice you provided onlist a opreport log, which I'm more used to deal with.

Top callers are: 95053 20.8283 libgcc_s.so.1 /lib/libgcc_s.so.1 75516 16.5473 libSDL-1.2.so.0.11.1 BlitNtoNPixelAlpha 41306 9.0511 libc-2.5.so /lib/libc-2.5.so I'm a bit surprised by first one, as I'm not sure what is called; maybe threads logic, but it would be surprising. For the libc call, it's probably memcopies. Optimizing BlitNtoNPixelAlpha would be worthwhile, but I think it's very general purpose (32 to 24, 24 to 16 etc). And halving its execution time would only bring like 8% speedup, almost negligible. Last profile is also surprising: it shows that character animation (not really surprising in fact: for the same screen, you now have twice more characters to display) and AI become more expensive. Well... Food for thought... Thanks for the report!
