XP and Win2K graphic rendering

Hi experts,
Could you explain what is the difference between XP and Win2K graphic rendering?
I asked this question because my program paint a form with a huge tableLayoutPanel Control in split seconds in XP but more than 2 minutes in Windows 2000!

Superficially, it sounds like the XP box has a video card doing it in the hardware while the 2K box is doing it in the software.

Different video cards?
XP with DirectX and 2K not?

Hi cookre,

Thanks for responding, all the PC has same configuration. It's not the hardware issue.

More details:
A module of software was developed in XP. What it does is read some data from the database do some processing and paint a form with a huge tableLayoutPanel Control. In this PC, the whole process is done in less than a second.
Now, this piece of code paints slightly slower after integrated into mine.
And it is extremely slow after published and running on a client PC (W2K).

I need some advice on how I can troubleshoot this kind of a problem.

Same versions of DirectX?

I will verify.

Sorry for the delay. The DirectX are the same version.
This problem was ignored as there are other priority to take care of.
My apology.
