What steps will reproduce the problem?'s more noticiable on Megaman Network Transmition or Metroid Prime so
load Either of this.
2.On Megaman you will notice the slowdown as soon as you start the game
(the introduction video will play slow) and then going into the net you
will notice the background moves slow making the movementes looks like been
dragged... on Metroid go to an open section (like chozo ruins) or enter the
map screen and move the map (also it will look like been dragged)
3.if you compare r3661 with r3286 (for example) you will notice that this
version goes slower (do not compare with r3404 cuz this one is slow as well)

What is the expected output? What do you see instead?
It's not expected to have such slowdown on games (tested it on 7 so far,
included metal gear solid) or for example the map screen on metroid prime
(wich is basically pure lines with vectors) not to move like if it's
cutting frames (or been forcefully drag).
I just mentioned this games cuz you can see this very abruptly but there
are plenty of games to mention if you like me to (inluded Wii games).

What version of the product are you using? On what operating system?
r3661 x64 x32
Intel(R) Core2Duo 2.53 2gb
GeForce 8400 gt 512
windows vista ultimate

  • Status changed from New to Fixed

Supposed to be faster now in latest revision, but we do as much as we can for
compatibility, not speed.

well compatibility seems to be the same, since the same games that didn't worked b4
still does not work. The big improvement on this version is Zelda with sound and some
graphic problems fixed.
but for some reason i think that the slowdown is caused by the sound
i will check further
