How can I optimise AutoCAD to make it run faster?

My AutoCAD version is running very slowly. Does anyone have any tips for how to improve the performance and make the application run faster?

Thanks

Ok Great, your processor has 2 cores(2 Threads per core / 4 Threads total) all you have to do it set WHIPTHREAD system variable to one of the following:

0

No multithreaded processing; restricts regeneration and redraw processing to a single processor. This setting restores the behavior of AutoCAD 2000 and previous releases.

1

Regeneration multithreaded processing only; regeneration processing is distributed across two processors on a multiprocessor machine.

2

Redraw multithreaded processing only; redraw processing is distributed across two processors on a multiprocessor machine.

3

Regeneration and redraw multithreaded processing; regeneration and redraw processing is distributed across two processors on a multiprocessor machine.

Type WHIPTHREAD=3 in the command line and tell me how it goes ?

To be brutally honest with you

AutoCAD only supports multi-core technology in specific areas of the product, including:

  • 2D regeneration
  • MentalRay rendering

Hi there Tamer,

 

What are your current system specs,

 

if your processor supports multiple cores we’ll enable the multi threading option and I promise you’ll be racing through tasks.

 

Cheers 🙂
