So this morning I got a new work computer to replace my aging laptop. It's nothing special at all -- HP desktop, 3 Ghz Core2Duo, 4 gigs RAM, Windows 7. My Mac is a Macbook Pro, 2.4 Ghz Core2Duo, 4 gigs RAM, running Mountain Lion. So the specs of the two are pretty similar with the only real differences being the nominal difference in CPU speed and of course operating system. I installed OV3 on the PC to see what the difference in speed would be. I was blown away. On the PC, it's MUCH more responsive when making edits, browsing through pictures, etc. And the RAW to TIFF conversion time is right around 1/2 what it is on my Mac -- around 15 seconds per pic on the PC vs. 25-30 on the Macbook. I was honestly shocked. But the conversion time isn't the real tangible difference. The whole interface on the PC version is just so much quicker. This tells me that Olympus has put very little effort into optimizing the code for the Mac version and that's pretty disappointing to me. I guess my point in posting this is to get some sympathy for those of us who are using OV3 on a Mac. We are in much more pain than the PC folks. Well, I say "we" -- I'll be using it on my work computer from this point forward. Just gotta try to profile this crappy monitor now.
