I would wait a few weeks for Melody from NVIDIA.
It was planned for GDC release, however now it will be released during WinHEC.
Unsure why it wasn't released before, we've had a copy of it since December...
(yeah that is roughly how long it is between the Release Candidates and public release for nvidia)
I woul really suggest waiting for it though, it is 13MB; v.fast and extremely easy to use.
Results in Real-Time, plus texture editing and so many options for optimisation you don't know what to do with them all.
I will see if I can't grab some High Poly model, remake it low and show you the results. (as we don't get any media with ours cept Dawn)
