In ArchiCAD (v11 and 12) I get a LOT of flicker when navigating the 3D window with OpenGL enabled. The flicker seems related to the z-buffer, since I see through walls when the flicker occurs. Anyone else have this problem or know how to fix? Thanks.</T></DIV> Sat, 13 Jun 2009 00:52:39 GMT genarch 2009-06-13T00:52:39Z https://community.graphisoft.com/t5/Installation-update/ATi-x1900-Mac-Pro-ACv11-3D-Window-Flickering/m-p/145693#M16510 <DIV class="actalk-migrated-content"><T>I have a Mac Pro running OS 10.5.7 with an ATI Radeon x1900 graphics card.
