View Full Version : Question. Does reaper support an I9 10 core processor

Hi all

I've just gone to an I9 10 core machine.

Reaper seems to automatically limit it to "16" (in the auto detect) but should I change this to 20 (to take into account hyperthreaded cores too or 10 or is 16 the limit?

Also, Live fx recommends limiting to 4 in the tips bit at the bottom.. still the case?

I recall Justin saying it should in theory support as many cores as you have and I've seen tests for the 10 and 12 cores so anyone have some grounded advice on what to set both these settings to? :)

Thanks!

In case anyone searches for this question. Justin did reply with the below which might be helpful. more info in that thread too. :)

Also: to be clear.

1) Enable MMCSS by setting it in Preferences/Audio Device. If you're using ASIO, there's an option to defer to the driver's choice.

2) If MMCSS is enabled for the audio device and prefs/buffering/Thread Priority is set to Highest or Time Critical, then MMCSS will be used for any "live FX multiprocessing" threads.

3) If MMCSS is enabled for the audio device and prefs/buffering/Thread Priority is set to Time Critical, then MMCSS will also be used for anticipative FX/media worker threads. This is not recommended in general!

There is a limit on the number of MMCSS threads (14, was it?), but as long as you don't set the buffering priority to Time Critical, and don't set the Live FX multiprocessing amount above 14, you will be fine. The worker thread count (reading/processing threads) can go higher, though by default it won't go above 16 without manual override.
