Response time issue in GT3

[Bulls Hit]

Recently I've been looping stuff a lot more inside GT3 - splitting segments of audio into clips and repeating them.

So I've recorded say 20 tracks, I've applied a couple of dozen plugins and it's playing back fine, and editing (copy, drag etc.) is snappy.

However the more I split & copy/paste and drag things around, the more and more sluggish the thing gets. Playback is still fine, no pops or dropouts but I might have to wait maybe 10 seconds to drag some clips around.

Project size will be around 1 - 2GB.

The Cakewalk CPU meters don't show anything going on, but Task Manager has GT3 running at around 50% (never over 50% for some reason). There's no disk activity. All of the time seems to be spent in calculations.

If I close the project down, and reopen it, it's gets slightly better for a while, then just slows right down again.

Anyone else experience this?

I'm running a 2.8 P4 clocked to 3.4 & 1GB ram with a dedicated audio disk drive. I have hyperthreading enabled. For some reason it seems to get cpu bound the more edits that are done. I'm wondering if there's some way to optimise things here

Obvious question I suppose, but are you running any virus checkers at all? Do you have spyware you don't know about? Have you done projects of this size before with your overclocked Pentium?

[Bulls Hit]

No. I'm not running any extra s/w.

The unusual aspect to this behaviour is the way things get progressively slower, the more edits and loops that are made.

It's like the program has to maintain and update a large, ever expanding stack of pointers or something

Might just be the P4 mate

[Bulls Hit]

Heh, AMD user right?

The thing with this is that I've done plenty of bigger projects, more tracks, more plugs etc. The P4 starts to hit the wall when I get to around 30 tracks at 24/88 with plugs on every track, stutters, dropouts etc. I know what that sounds like. If I mix down and archive a bunch of tracks it gets better.

However this is different. The more I split and repeat clips, copy& paste them, it's like cycling up a hill that gets steeper & steeper

[Monkey Allen]

Yeah, I used to be P4, AMD now. Is this happening with all your projects lately? Maybe this one where you are copying and splitting has corrupt sound files in it or something? Sorry, I'm just not coming up with anything here at the moment...
