How can I get this to use a set number of cores to be the default?
As it is now I must reset this for every conversion performed, I'd just like to set it once and have it use as default setting.
Thanks

Yes include the DSP effect 'CPU Force'

Aaaah, thank you, don't know how I missed it.
OK, just tried this . . . I set DSP to Force Multi-Core, selected 6 of 8 cores and converted a folder.
It indicate that it is converting using 1 core until I manually tell it to use 6 cores.
I'd really like to to be a sticky setting.

What do you encode to? 'Multi Encoder'?

I tried converting a folder of FLAC files to mp3
I first selected the files in the folderand right-clicked "Convert To"
Next I tried selecting a folder and clicking 'Batch Convert"
In both cases only a single core was being used to convert 1 file at a time, even though the DSP "Multi-CPU Force" was selected.
Run dBpoweramp Control Centre please and check you have dBpoweramp Reference Registered.

I have:
Release 16.6 [64-bit] registered
I don't know what I had done wrong but I re-tested today and looking at Windows Performance Monitor I can see all the cores working.
sorry for the confusion

after further testing, something just doesn't seem right . . .
While the DSP to force Multi-Core appears to work (all cores appear loaded when watching Windows Performance Monitor, batch conversion still seems slow.
When I also manually click on: Options ->Encoding ->Use 6 Cores, the conversion speed increases as shown by the "Time Remaining" suddenly drops and conversion speed increases.
Why would there be a difference when I'd expect both commands should cause the same effect? Am I misinterpreting something?
How many real cores does your system have?

It has 6 actual cores, no virtual cores.
I normally use 4 for batch work but it will pull 6 conversions and still let me play music and such.
I used 6 both with the DSP and then again manually.
If all the CPUs are 100% for both tests then I cannot see why one method would be faster than the other.

I didn't say they were all at 100%, I said they all showed a load.
But when I also manually click the option to use 6 cores while it is converting using the DSP, the Time Remaining suddenly drops and starts timing down much more quickly. You can see a noticeable increase in speed.
I will test a group of files both ways and note the difference in time to complete.
be back soon
OK I ran a better test: converted 102 FLAC files to mp3 (V0) as a Batch Conversion
1) Ran batch using DSP set to Multi-Core Force set to use all cores:
Time to complete: 4 min 31 Sec
encoding speed: 75 - 80x
CPU Load: 30-40% @ 3.89 GHz
2) Ran batch with force multi-core DSP removed, started conversion and clicked "Options: Encoding- Using 6 cores"
Time to Complete: 1 min 25 sec
encoding speed: 200 - 250 x
CPU Load: 90-100% @ 3.89 GHz
Re-Boot machine, run verification tests:
3) Repeat test 2:
Time to Complete: 1 min 3 sec
encoding speed: 337 x encoding speed
CPU Load: 90-100% @ 3.89 GHz
4) Repeat test 1:
Time to complete: 4 min 21 Sec
encoding speed: 81x
CPU Load: 25-30% @ 3.79 GHz
So, as I stated, when using the Force Multi-Core DSP conversion IS considerably slower than when manually setting "Options: Encoding- Using 6 cores".
I'd like not to have to manually set this every time I do a batch and still get the same fast conversion.
I ran a test and converted 102 FLAC to mp3 (-V 0)
Test 1: DSP set to use 6 cores = 4 min 31 Sec / 75 - 80x encoding speed / 30- 40% CPU load
Test 2: Same files, same settings but with DSP removed, manually set to 6 cores using:
"Options: Encoding - 6 cores"
= 1 min 25 sec / 200 - 250 x encoding speed / 90-100% CPU load
it is faster when set manually.
Thanks for your report, we will run this exact test soon.
