I'm working on a patch that I can't get to run the way that it should. I can't find a solution to stabilize my Fps. I'm wondering if perhaps a stronger CPU might be a solution.

I run Max 5 on a PC (laptop) Dual Core 2.16Ghz and 3Gig Ram.

- Does anyone know if Max/Jitter would benefit from running on a quad-core or eight-core ? Does Max recognizes and uses multi processing ?

- Does max QTgrab work better then max DXgrab ? 

I might buy me a mac and I was wondering if it would have any advantages, other then being a mac.

The patch I'm having trouble with has to grab live video (360/288), record it (360/288), play it with a delay of 3 minutes. + it has to read a second movie (360/288) and apply an alpha key on it. all in real time.

I can post the patch if someone wants to have a look at it...

I don't think Macs are better at doing Jitter, I even heard rumors of people

saying jitter runs a bit better on windows, but I can't confirm this. You

don't get any advantage from having multiple processors if you don't design

your patch the right way. You need to either make use of poly or run

multiple instances of your patch simultaneously with Max Runtime. The latter

will result in the use of different threads/cpu's for each instance.

- make sure your harddrive is fast enough and use a RAID or, even better,

- record and playback in a compression format which has good cpu/bandwidth

ratio for realtime use. PhotoJPG @70% is very common for example.

- if the actual processing of the video is killing the cpu, consider using

slabs and shaders (possibly in combination with asyncread) to tax your GPU

Posting a patch is always a good idea if you want people to help you.

Just some obvious things I can think of:
- make sure your harddrive is fast enough and use a RAID or, even better,
SSD if that proves to be the bottleneck.
- record and playback in a compression format which has good cpu/bandwidth
ratio for realtime use. PhotoJPG @70% is very common for example.
- if the actual processing of the video is killing the cpu, consider using
slabs and shaders (possibly in combination with asyncread) to tax your GPU
instead.

the patch I'm having trouble with is made in max 5.

this is part of the patch, mainly the recording and playback mode.

thank you for your response.
