TChart Slow Performance compared to D6/D7

The .NET for VCL TChart is very slow when rotating a surface series, or TPoint3DSeries compared to the D6 version. In D6 it's lightning fast, same code - dead slow in D2005.

There seems to be times where the Chart stops responding while it 'does something' in the background.

We've all had to upgrade to P4 3.4GHz PCs with 2GB RAM because Delphi 2005 is so sluggish. Its not made much difference but the slow performance of TChart on this spec of machine means it's going to be totally un-usable for our existing clients.

Are you aware of the problems and what are the plans or reason for the poor performance?

Many Thanks in advance

Hi

Welcome to .NET <g>. Yes, I'm getting the same slow downs, mainly because of .NET arhitecture and it's assemblies. The same application, compiled and run in D2005 W32 works a lot faster.
