Hi All

I have Draft Sight installed on an AMD Phenom 9850 Quad core 2.5GHz PC with 4GB of RAm and a Geforce 8100 / nforce710a graphics card.

When zooming in and out with the scroll wheel, the screen does not move smoothly and responds in a jerky fashion, making it unpleasant to use.

I was wondering if Draft Sight is more reliant on RAM or graphics card performance before I consider upgrading either part.

I have seen in other questions about disabling the graphics card and re-checking, I have tried this.  Initially the resolution drops to 800x600, at this setting zooming is fine.  However as soon as I raise the resolution back up the system become jerky again.

I have checked and the graphics card drivers are up to date.

any thoughts

Thank you

Chris.
