So the issues you are seeing is because you are using the scfb driver which is a software only driver. So it would be expected to see really poor performance of 3d applications, as well as others which require hardware acceleration failing to start. i am not sure about the status of DRM on apple hardware but there might be someone on this or the freebsd-x11@ list who can let you know if hardware acceleration is supported. cheers, -pete -- Pete Wright pete@nomadlogic.org @nomadlogicLA
