Choppy drawing

[ptc-2326978]

I have installed Direct Modelling Express 4.0 on a Dell Vostro laptop and I am having some chopping/lagging problems, but only while drawing. If I am just rotating/zooming a model everything is fast and smooth, but the second I start to draw anything the cursor jumps and skips around quite a bit. The laptop uses Intel HD 3000 graphics.

Anyone have any ideas on how to fix this?

Hi Tom, thanks for the quick reply. I typed the command and the response was "NIL", so I assume openGL is working. I would like to clarify that my problem does not occure when making drawings, but when attempting to draw a feature on a part. For example, drawing a circle on a workplane before pulling it. I have tired turing off all CoPilot setting thinking that might be a problem, but that made no difference. The slowdown occures even when draing a shape on an empty workplane in a new file.

The computer is a i5-2410M w/4gig ram, Win7 64bit.

Hi Tomas,

I faced the same problem too when running PTC Creo direct modeling/CoCreate in my HP Zbook laptop.

I managed to resolve the problem by switching to dedicated graphic card. Some laptop have both integrated graphic card and dedicated graphic card. By default the "smart" system will choose which one to use. By switching your preferred graphic card to 'dedicated graphic card' instead of 'auto-select' may solve your issue.

Regarding how to set your default graphic card, i think is vary for different graphic card maker. For my NVIDIA:
Right click on desktop>NVIDIA Control Panel>Manage 3D settings>Preferred graphics processor>(Select your dedicated grahic card).

If your laptop doesn't have dedicated graphic card, then may be is your graphic card underspec, probably not enough memory. Some BIOS allow you to allocate more memory to your graphic card. That may help with the issue.

Hope this help
