With Wine (on Mac OS X), starting with version 1.5.1, the games rFactor and GTR 2 run slowly / run with laggy jerky video (which they didn't do so with Wine versions 1.5.0 and earlier).
(And, also, I think that, with Wine (on Mac OS X), starting with Wine version 1.5.1, the program VSTHost maybe runs using more CPU power? / runs less efficiently? (than it did with Wine versions 1.5.0 and earlier.))
I think that, if, in fact, VSTHost is now running more slowly, I think that that may have begun with Wine version 1.5.0 or with Wine version 1.4.0.
