It is not about money! I was considering a lot of time, that I would need a new machine.
But it is very tough to put a new system together with the huge number of programs collected over several years.
I increased pagefile size (min 5GB, max 10GB), but no change.
What may be
"considered" although:
The game was working
ON THIS HW (with this size of memory and this video card) with the universal MS video driver.
But it crashes with the ATI driver.
Pelele's comment #10891 also strengthens driver problem:
You must be registered to see the links
But the problem is now that I can not rollback the driver, because there was an "universal" and an "Unknown" Display adapter in the Device Manager.
I tried to get the windows to find again a video driver,
but it says, that the driver is up-to-date and it does not offer the MS universal video driver.
