CPU consumption general question

ELIBEEMER · Messages: 2,452 Registration: 02.27.2001

Ok so I launched my latest session in Reaper, shut all the background software to have more headroom with my resources, and this is what I get : Can anyone help me figure out WHY my CPU usage is at over 50% while Reaper and it`s FX are taking only 13-14%? I literally have only AVG running!

Press CTRL+ALT+DELETE on your keyboard to open windows task manager, Click on the "Processes" Tab, then double-click the CPU column header to sort processes by CPU usage.

Time stretching or resampling happening on the media items? Those can quickly chew up additional CPU that isn't shown on the FX CPU load section.

well for starters, its a stationary, not a laptop. This screen was taken when reaper wasn`t playing anything (just loaded a project, didn`t play it). I removed anything I knew I could from the Task Manager (all 'updates manager' stuff and crap like that). I had two instances of Firefox running apart from Reaper. Does reaper consume a lot of CPU, apart from the FX?

Thanks. I tried this : launched Reapers performance Meter AND the Task Managers Performance Meter. It appears all that % IS coming from Reaper, as without Reaper running I get 0-1%. I run a Core 2 Duo 1,8Mhz with 2GB Ram, I thought this wasn`t THAT low...

44.1/32 this session was recorded with reaper (all the items) so they match.

Make a copy of your project, then delete tracks one by one, watching task manager and reaper performance meter drop after each deletion. Is the CPU load evenly distributed over tracks?

Process Explorer

I don't have an answer to the problem but I have seen many references in different threads concerning the Reaper performance window, Windows Task Manager etc. One tool that far outweighs Task Manager in this department is Process Explorer by SysInternals (MS). You load it up and double click on reaper.exe in the process list and you'll get much more information about the running instance of reaper including all the dlls, files, handles etc it has loaded/open including performance graphs just for the that single process... At minimum, you can confirm exactly how much CPU is due to Reaper as a whole: No install needed, just click and run... As far as narrowning down the issue, I suppose you could launch reaper and globally take all FX Offline, see if the usage drops, and if so, then enable them 1 by 1 till you find the culprit(s). Oops, I think I just made my first post... :-) Just an FYI- Karbo
