Bugs / AntialiasingNotAvailableWithCertainVideoCards


Antialiasing is not Available on Computers with Certain Video Cards

by TamasEros, updated 2013-06-04 • ArchiCAD16ArchiCAD17 • Mac OS X only • RefID: 141046; 142609 • Limitation

Issue

The 3D view does not seem to use antialiasing. Warning message appears in the Work Environment settings window at Advanced Redraw Options: "Warning: Antialiased drawing has been automatically disabled due to insufficient video card resources."

The problem occurs on MACs with mainly AMD video cards but some configuration with NVIDIA or Intel card are affected as well.

Cause

Antialiasing is turned off by ArchiCAD for the following video cards because some functions in the video card drivers contain bugs. These bugs cause that some of ArchiCAD's new features do not work properly when antialiasing is active or can result in crashes. The affected video card range depends on the version of the Operating System and ArchiCAD.

ArchiCAD 16 Hotfix 3 (build 3487)

OS X 10.6

  • All AMD (formerly: ATI) video cards
  • NVIDIA GeForce GT 330M

  • NVIDIA GeForce 9400

  • NVIDIA GeForce 320M

OS X 10.7

  • All AMD (formerly: ATI) video cards
  • Intel HD Graphics 3000

OS X 10.8

  • ATI Radeon HD 2600 PRO
  • ATI Radeon HD 4670

ArchiCAD 17

OS X 10.6

  • All AMD (formerly: ATI) video cards
  • All Intel video cards
  • NVIDIA GeForce 9400M - Since Hotfix 2 (build 4005)

OS X 10.7

  • ATI Radeon HD 2600 PRO
  • ATI Radeon HD 4670
  • ATI Radeon HD 4850
  • ATI Radeon HD 4870
  • ATI Radeon X1600
  • ATI Radeon X1900
  • Intel GMA X3100

OS X 10.8

  • ATI Radeon HD 2600 PRO
  • ATI Radeon HD 4670
  • ATI Radeon HD 4850
  • ATI Radeon HD 4870

Solution

If your video card is in the list above, but you need to have antialiased 3D display, you can turn it back on with a plist tweak (detailed below) at the cost of loosing many of the 3D window's feedback guides:

  • The automatically resizing Editing Plane ("the blue grid")
  • Real-time feedback during repositioning the Editing Plane
  • Plane selector around the cursor ("the gray rectangle")
  • Cutting plane display ("the red plane")

  • shaded feedback will be exchanged with wireframe while editing a Morph

  • texture positioning feedback on a Morph face
  • protractor feedback for 3D rotate

How to turn on Antialiasing

  • You will need a Pref Setter application to edit the plist. (available here)

  • Launch Pref Setter
  • Open 'com.graphisoft.AC-64 16.0.0 INT v1.plist' from User Preferences
  • In OpenGL dictionary set the value of '3D Shaded Feedback Fallback' to 1
  • Save the plist and restart ArchICAD 16.

Later when this problem will have been solved it will not be necessary to set this plist key back, ArchiCAD will do it automatically.
