Enable your software to take advantage of more hardware power.

Tipster Leigh Lundy sends in a tip to help AutoCAD Map 3D users increase the visual performance of their hardware while drawing.

"I found that when I was drawing in AutoCAD Map 3D 2011, my crosshair was acting like it was being dragged across a rough surface. Instead of being a fluid motion from one point to another, it was rather jerky.

"After tweaking my settings, I found a way to stop the problem. Here are the steps I followed:
Options > System tab > 3D Performance Settings > Manual Tune > check the Enable Hardware Acceleration box."

Notes from Cadalyst Tip Patrol: This tip was sent to us by an AutoCAD Map 3D user, but the good news is that it works in AutoCAD and all AutoCAD verticals, not just Map 3D. This setting controls hardware acceleration, meaning the settings allow hardware to increase the performance of software by using more than the general-purpose CPU. If you have a GPU, AutoCAD will take advantage of it, thereby increasing your performance. When the Enable Hardware Acceleration box mentioned above is not checked, hardware acceleration is not used.

funny thing is, you would think hardware accelleration would help with 3d solids, but it seems to do the reverse. When on, it makes solids look like they have been crumpled up. It may be that I am working on coordinates far from 0,0, but its consistent. So each person has to decide if it hurts or helps them. Also, its generally on by default I think, for current systems. You only start to care when you have to turn it off, from what I have seen.
