Re: How Designer Pro uses multi-threading
Phil, it would be interesting to see comparative stats or graphs showing the difference.
I was curious enough back in 2013 to do a quick, non-scientific test comparing the then current versions of PGD and the multi-core DPX.
For my test I created a group of 16,000 ellipses (a large enough number to take time to measure!), then timed how long it took to clone the group in each programme. By reviewing the CPU usage history in Windows task manager, it seemed that DPX appeared to balance the load between the two cores more evenly and less time to complete the task. This was estimated by the fact activity spiked and finished earlier in the usage history graph (below).
The difference was not perhaps as much as I was hoping for in normal day-to-day usage, but I was testing with a basic duel core processor with a limited amount of RAM. Where it did make a noticeable difference (smoother rendering) was when dragging a complex 3D shape about the page.
