I done some more testing of Mac visa vi XP on Parallels
First I updated to PTGui 7.2 on XP
This seems to show that PTGui 7.2 is slightly slower which I also heard from the Group
while beta testing
the speedtest file gives me this.
Old tests 6.03 = 2.20 - 2.30
New test with 7.2 = 2.40
As running it in parallels means that you use 100% CPU (1 core) I also tested it running it
simultaneously on Mac and XP.
Result was this
Mac 2.50 (increasing from 1.08 when run alone)
XP 3.40
One thing which can affect the slow Windows performance could be the pano12 version.
As this test is run with panotools warping this could probably make a big difference.
I have tested the PTgui warping on both Mac and windows and without fast transform it
gives me this after reboot
XP 3.20
Mac 2.40
Using fast transform with PTGui warping speeds it up 100% both on Win and Mac but using
fast transform with Panotools warping makes almost no difference.
This is using the panotools (version 2.7.0.9/nh1) for Windows
and the pano12.dll from Jim Watters. As you can see he has 2 versions. The one I have is
the MinGW slower one which Joost recommends.
pano12.dll [Version: 2.8.0 MSVS Size: 367KB] (Faster but may cause crash when used with
PTStitcher)
pano12.dll [Version: 2.8.0 MinGW Size: 253KB] (slower by 25% to 50%, but stable with
PTStitcher).
On Mac we have no real Panotools but it is all in one special file called panotools.bundle
