Hosts & Applications (Sequencers, DAWs, Audio Editors, etc.) • Re: Reaper: Massive rise in CPU usage, why?

You mention setting power plan to Performance meaning it's allowed 100% cpu. This might be needed for trouble free audio, not sure.
- but if worried, set that down to something else like 80% and let things take longer if audio still ok.

You mentioned having spikes of 100% cpu.
- for how long?
- more than 30s constant 100%?

Are you using Task Manager readings?
- you can also see specific cores
- are all using 100%?

This is computer cpu use, not only Reaper then.
- daws own reports on cpu I do not trust that much

What cpu are you having on that laptop?
-Intel and which generation?
- AMD? (No clue if HP do AMD also.)

From 12th generation Intel there are E-cores as well, running half speed just about compared to P-cores.
- not much software still is taking this into account but let windows place threads on all cores as they were alike

What could happend is that Cockos made Reaper target P-cores which are stronger and not E-cores anymore and Task Manager show spikes.
- Cockos team is in the forefront of most things and quite possible
- so they optimized for render to take less time

Are you running Reaper v7.34 March 2nd?
- update if not

Read the manual which most often is updated as new features are around. See what those new options for render mean, that you did not see before.

I think Cockos forum or Cockos team is better. You got plenty good suggestions from everybody here and it did not help.
- everybody seem to fail reading what you mean
- everybody "misread" you

I assume you are a paying Reaper user.

If running normal at 5% at playback as I read in your post, no need to worry what offline fast rendering is at!!!!!
- just let it do it's thing
- or lower allowed cpu at Power Scheme settings in windows if worried
