Hi,

Can you specify which graphic card you use and the driver version.
All this problem are generally related to that.

I do the first test with Vista at the end of last year to check that
all is working, principally the installer. For the convenience I do
that within a virtual machine but with the drawback it not let me
test a real graphic driver.

So yesterday I put an old 20GB drive on my computer to install Vista
for a test with my two available graphic card: the mainboard Intel
82915 and a Nvidia 6600.

I first install the VMA Expert version and then the VMA Pro.
In all the case the program run fine and I don't encounter any
problem, I run it with about all the options for a hundred of time.

The only problem was the performance with the default Vista drivers,
I summarize that below:

Intel 82915
Vista driver version 6.14.10.4656
resolution 1680x1050, 32bit color
Windows experience index for 3D graphic : 1.0
VMA Pro frame rate : 3
apparently no OpenGL acceleration
Unfortunately no new driver available for Vista on Intel web site.

Nvidia 6600
Vista driver version 7.15.10.9746
resolution 1680x1050, 32bit color
Windows experience index for 3D graphic : 3.8
VMA Pro frame rate : 3
apparently no OpenGL acceleration

Nvidia 6600
Last beta driver from Nvidia version 7.15.11.5818
resolution 1680x1050, 32bit color
Windows experience index for 3D graphic : 3.8
VMA Pro frame rate : 70 to 200 depending on the setting
full OpenGL acceleration

It look like you need a vendor driver for OpenGL acceleration, the
Vista drivers don't include that!

Any people here with Vista experience ?
it may be interesting to hear ATI user's.
