Re: NVidia 173.x driver and FreeBSD 8
The 173.xx FreeBSD graphics driver series hasn't been updated to take advantage of features available in the FreeBSD 8 kernel, and still employs a variety of workarounds originally designed to address limitations in older kernels. Due mainly to this, the driver isn't guaranteed to work (it may simply hang, for example), and it may suffer from performance problems in some situations.
That said, we do still plan on updating the legacy drivers to work with current versions of FreeBSD. However, this work is gated by backports of key infrastructure and unfortunately prioritized behind other work. As a result, it has been progressing very slowly.
