Just updated Basecamp to 4.1.2. It says "can't display in 3d update video driver". Not sure it showed 3D before the update.
My ATI video driver is up to date. Video is 256mb ATI Radeon X1300PRO, using driver version 7.01.01.646. The ATI control utility says both GL and 3D are enabled, the DirectX 11 Diagnostic shows DirectDraw, Direct3D, and APG texture are enabled. The driver here shows 7.14.0010.0503 in use, and the Notes box says "No problem found".
Also the 'System Information' Summary shows no Problem Devices.
Google Earth 3D shows up fine.
So what is the problem that Basecamp does not like my video card.
