Trying to ascertain which motherboards/CPU's work well in T3 with more than 2 cores enabled. Most of the time we hear from people who's performance/stability goes haywire unless the number of usable cores is reduced to 2 in t3. However, for some it's okay with more than 2. This seems to be machine and architecture-dependent.

It would be useful to the community (and to me!) to know which >2 core architectures t3 seems to like and which it doesn't.

If you are running t3 on a machine with more than 2 cores, please answer the following questions one by one:

1. What is your motherboard chipset and CPU? (no motherboard model numbers or brands, _please_). If a Mac, please just state model of mac.
2. Can you enable more than 2 cores in T3 without loss of performance or stability? If so, does the performance increase? (please note that t3 assigns each track to one of the available cores - so a 4-track project with effects on each track would be the minimum to test a quad-core setup)
3. Do you mostly do wav audio projects or softsynth projects?
4. What OS and service pack are you running?

Thanks to all-

LOL an old topic but i downloaded tracktion demo on my mac last night


mac book pro 8 threads (4 cores) 2.2ghz

8gb ram

and tracktion actually runs well! there is just one major bug where time stretching crashes the program when changing algorithms, so the key is not to use the TS, otherwise tracktion is usable! SOme modern plugins guis are a tad flaky too but i haven't had an actual plugin CRASH yet..

I have all 8 threads enabled and performance goes alot worse if choose only one. I tried 4 instances of sylenth playing the full, 32 voices each and i confirmed the load was evenly spread amongst 4 cores. Tracktion puts everything on one core when you start using multi outs and bussing, so the key is to route carefully.

Quite amusing cause i thought tracktion was not supposed to work at all on newer macs, i'm on snow leopard 10.6.8

everything i remember and love about this program is still valid.. sigh....

Just a small bug fix update and it would be a really good solid host still.

What a shame.

Did you try it with 4 vs 2 cores enabled?

yes.. it's all in my tracktion topic in the host section..

the difference is about 4 x more plugins with 4 cores enabled than with one or 2.

so it's working.

but at projects with little effects, higher cores causes erratic cpu behaviour..

so it's the same as the windows version.

it balances out as you add effects.

if i was going to do a project without vsti and just a few effects, i'd probably set it to 2 cores just to keep the cpu low.

No worries - you just mentioned comparing against 1 core not 2, so thought I would check.

Also, are you mainly using vsti's or are you using recorded audio tracks?
