DVDrip and transcode work fine for me under 64-bit. While there are |
| 10 |
issuse with 32-bit only codecs, they can be worked around in multiple |
| 11 |
ways, including a 32-bit chroot environment. |

Try adding the following for video output - "-vo sdl" |
| 14 |
|
| 15 |
It solves some of the issues. |

I suggest that something is set up incorrectly or your comparision is off for some |
| 22 |
reason. Though, the Opterons do transfer a full 64-bit word containing a 32-bit |
| 23 |
value for each audio packet. In general, I've not seen my dual Opteron to be |
| 24 |
slower than the dual AthlonMP I ran. Converting to ogg with grip, is faster |
| 25 |
on my dual Opteron system. |

Desktop apps are fine at 16-bit. Why go to 32-bit? |

Perhaps you don't run the 64-bit version of ut2004 or doom3? |

Simple, at 64-bit, one can run both 64-bit apps and 32-bit apps. At 32-bit, |
| 46 |
one can only run 32-bit apps. And 64-bit apps will take advantage of the |
| 47 |
extra register set. A 64-bit kernel provides a faster os due to being more |
| 48 |
efficient, and having access to the extra registers. |

In gentoo the make.conf CFLAGS becomes - "-mach=k8", while for 32-bit, both |
| 51 |
"-mach=k7" and the USE flags - mmx, sse, sse2, (perhaps) sse3, 3dnow, and |
| 52 |
3dnowext, all need to be set. Otherwise, your performance suffers when doing |
| 53 |
video. |
