Just to state the obvious: SFP is not a pro mixing desk, IMO it's much more, so it has a lot more work to do than a mixing desk. I'm sure they could make the VU meters faster if SFP was only coded for mixing, but it isn't.I believe a package of this calibre should be able to at least come close to matching the VU response of a pro mixing desk, for example. So far, SFP pales in comparison.
And to be honest, the VU meters seem to be pretty accurate anyway, and definitely faster than on older pulsar versions.
So is it just the VU meters or are there any other noticable slowdowns for you?
btw. I have a pretty old ATI Rage 128 (or something like that) videocard.
