I know that from v8 to v9 there was a difference.
I read that v10 is going to be faster (from web site)
* New “Fast Views” means complex models are projected to a drawing 4-10 times faster.
* 25% decrease in memory consumption for Fast Views. General memory consumption improvements. On average in v10, equivalent drawing workflows can be completed in half the time with only about 65% of the memory consumed in v9.2.
* More responsive detailing.
* Drawing views update after a model edit without having to close and reopen drawings.
What are the system requirements for Alibre v10?
Are these percentages above based on the same computer being used?
Best we can tell it is.....
The kicker though may be that if there are new acis modules and new features then some things may not be able to work on older systems. It may be one of those try it and see things.
