Maybe my machine is faster than yours, but I don’t have any performance issues when the GridCellSize is 4x4 and the GridMajorLineFrequency is 4x4 and the GridStyle is Dot or Cross.
The performance is horrible, also with the Properties window closed.With the application zoomed full (1920 x 1200), the Overview window lags behind about a second when I drag it across the diagram.
That’s odd, because I don’t experience any such delays no matter what I do, including everything that you have described. My machine is actually a dual processor, but at 2 Ghz. My monitor is also 1920x1200. Win XP SP2, all the latest updates except for IE7. GoDiagram 184.108.40.206 (.NET 2.0). I’m running the Demo1.exe from the installation kit.
The performance especially seems to degrade when zoomed out, e.g. down to 50% or lower.
Yes, that makes sense, because there would be a lot more lines to draw when zoomed out. With a GridStyle Dot or Cross that can mean millions of little lines.
