Topic: Podium / CPU Performance

Hi,

I’m not aware of any plugin CPU consumption problems with Podium. I’ve also spent quite some time optimizing the engine, so as far as I know, there are no areas left that needs to be optimized.

Is your problem that the Podium CPU indicator reaches 100 sooner than it would in Cubase? Or does the audio start to crackle before reaching 100?

Some things to check:
Try increasing the ASIO buffer size a notch and see what this does to the CPU performance.
Check that the engine is running in 32-bit and not 64-bit mode.
Check that multiprocessing is enabled (if your AMD chip supports that).

Podiums CPU measurement may be different from Cubase, so you need to push the CPU much higher than 11/12 percent before you can make a reliable estimate on the general plugin CPU performance.

When the project started,the cpu indicator overloaded& stopping the project play. In 32 bit mode also. the latency 7ms. When using Ctrl+space tabs: project go and the end of wawe files also stopping and not work.(24/48khz)

Try increasing the ASIO buffer size (latency). Try muting all of your VST tracks, and then unmute one at the time until you find the plugins that makes the CPU indicator jump up. You could then bounce the heavy-CPU tracks.

Try dropping your latency back down and see if it helps. It’s funny but it seems that with Podium I have much fewer problesm with lower latencies. I am using the Presonus Inspire.

Hi,

Yes am using latest presonus asio drivers

Tried dropping latency in drivers down to 4ms.
Seemed to make no difference on spikes or on avg of CPU monitor (40-50% avg in proj I am testing with now with lots of reverb etc.)

Still get dropouts even with minimal tracks unmuted and avg cpu of 20-30%

Also forgot to mention am using 44.1 khz sample rate.

Just now I had sysinternals process explorer running now and it made tons of spikes appear, but I don’t usually run this only running it now to see what’s going on.
(BTW Podium is running at 30% of my machines CPU)

Podium seems to be using both by CPU graphs.

BTW: Are onaccess virus scanners known to cause issues?

Spikes do not seem ro be regular intervals usually.
When using processexplorer I get regular spikes but obviously this isn’t a problem I don’t run process explorer or task mgr usually when running podium.

Oh yeah have tries multiporcessing flag before because of seing it on a previous post but again seemed to make no difference.

Do the spikes occur less frequently, if you increase the latency/buffer size?

Not easy to tell maybe a bit but stll seems random

Do the spikes occur more often if you move the mouse or press any keys?

No not that I can tell

I’ve had McAfee On access statistics window open and guess what…
Everytime a spike occured On Access scanner changed it’s last file scanned and upped it’s total number of files scanned.
I have a very string feeling that this is the cause. (I will confirm when i’ve has a word with work and see if I can turn on access scanner off, I use my work laptop becuase it’s more powerful that my other machine)

After you have had a few spikes, go to the report page in the interfaces dialog, and save a report. Paste the report here or email it to me.

OK…
Loads of reports here just so you can get a good feel for it
Minor note once seemed to get a load of audio glitches but nothing reporting in even though the report start/end included the time when it would have happened!!

Just for record it seems that is was the antivirus, i’ve been using it for ages now with no spikes whatever.
Though I did also stop a load of extra services that were running too. (Sql server, IIS, etc.)
I have a batch (.bat) file I run with a load of net stop commands, just thought I’d attach it in case others thought this might help them get more perf not really sure how useful it is though!
