- In this video I'll show you four things you can do to dramatically lower the CPU load in a REAPER project. In my example project of several virtual guitar amps and virtual drums I brought the CPU use from around 42% to just 5%.
* Increase audio device buffer size
* Applying fx to items
* Track Freeze
* Move tracks to Subproject

Reaper is awesome, its community is awesome. Thank you.
Facts
Couldn't agree more...
Oh my god, the sub project bus is a game changer! THANK YOU JON
Reaper is so dope that I'm sure it would run in a pager back in the days.
Im back into music creation because of reaper and linux!!!
Ya know, I was literally just searching around for this exact information a few weeks ago. Most of my projects end up containing 10+ songs, and around 300 channels. I’m always looking for ways to optimize my workflow.
Always informative, always easy to understand. Thanks for consistently being the best resource for reaper info online.
Nice to see you here josh, love your work man!
Thank you for these tips! What an amazing piece of software Reaper is.
Did not know the subproject feature, great! I used to do that "manually" for all drums or vocals, so much better this way..
Thanks!
Excellent advice Jon. . . and the fact you're doing this with heavy guitars makes things all the betterer! :D
The other option for long reverb tails (apart from extending the item length) is the "Include Tail When Freezing Entire Tracks" option on the Audio | Rendering page of the Preferences.
Thanks for the reminder!
Freeze/Unfreeze buttons added to toolbar. Totally awesome.
Golden tips I wasn't aware of! I didn't even know about the subprojects and unfreeze functions. Thanks a million!
On first viewing, this is mostly Greek to me but I have a zillion drum tracks for no reason and I've noticed that VSTs use a lot of CPU. In fact, Reaper busted my drive and I opened a new one just for Reaper and a video editor to free things up. The music is called "Marmite night"....I guess.
Thanks.......millions!
Hell yeah thanks for this tutorial, I was having issues on the playback for mixing with it being choppy and adjusted the settings like you said, CPU power is at half! Thank you
Thank you for sub project tips...... I was very puzzled 🙏🤘
No way! I never knew you could click the top of the window as a shortcut to device preferences! Thanks!
Thank you Jon for all the useful stuff you publish about Reaper.
Since you released this video, I began using freezing (offline FX) and subprojects on a daily basis. They now play a central part in my workflow, allowing me to manage huge projects without overloading my computer's CPU (at the cost of a bit of time to process the subprojects renders and freezing, but the benefits are superior to the drawbacks) !
Reaper is such a Beast!
My OCD asked me to ask you to go back and fix 'pick scrapes L' and 'Pick Scrapes R'. :D
Great tips. I did not know about the move tracks to sub project. That is a great tip and very useful.
Thanks, Jon.
Thanks for sharing! Love Reaper!
will watch later but man the track is brutal!
Haven't used subprojects yet. Thanks!
Man, This is impressive. I've started to like Reaper. THanks for this useful tip
nice! i was unaware of the subproject feature, that looks really useful!
Amazing! never new about this performance monitor thing!!! Wow!
Super tips! When dealing with my big orchestral template I have a custom action to bypass FX on empty tracks then a shortcut to activate them again.
Great stuff. Yup, freeze and subprojects are super helpful tools.
This is pretty cool, where is the performance master located
The mixing sub mixes technique is almost like precomposing in After Effects... You can condense a collection of elements together and affect them together, but when you want to go back into them and make edits you can
Great stuff! Thank you for your time and great videos.
thank you!
Did not expect such 5:50 sauce :^)
Greetings good sir!
Great video as usual. I was a bit confused by the Apply FX to Items bit. Is there some advantage to doing that vs freezing the whole track (as you subsequently did) beyond just being more targeted? You then pulled the items out into their own track. How come? I usually just freeze in that situation, but maybe I'm missing something?
just showing another way to do it. lots of people have tracks with fx for just a few seconds of audio.
Thx so much. Very interesting, as always!
Great tips!!! Thanks!!
Sub Projects *** mind blown ***
Incredible.
OMG this is going to change tons how I use Reaper, when having 100+ tracks my cpu and memory limits quickly my workflow. With a lot of frustrations. Subprojects are not bad; but I love to keep everything together. Thanks, Jon for this eye-opener here.
Awesome! Sub project I gotta try.
42% CPU? Reaper is literally showing 97% & sometimes higher every time I push play!!! 😱I can't even work on my song right now.
Update: The FIRST thing reduced the CPU usage to 92%! Mine looks different. It says 8 x 512. I changed the 512 to 1024. So far, so good! The song is now able to play without stuttering badly. I'm going to keep watching for the next 3 things.
Like n' a Sub from me brother! Very grateful for this tutorial my D'jazz Project sporadic remixes weren't bangers to say the least, thanks for the help!
Reaper performance meter is not showing ram usage when upgraded to windows 11. Neither in project window nor in performance meter. Please help.
wow, this subproject trick is freaking fat! Wow men!
Heading to your patreon for the tip, thank you
I remember in renoise I could double click the stop button to seize all processing activity, any such thing in reaper?
Hi and thanks. With my laptop I'm experiencing extremely long freeze times. Can you please tell me if there's a way to speed up the rendering of the tracks I want to freeze?
What theme are you using? Looks beautiful!
Lovin' that thicc play cursor.
❤❤❤❤ amazing
Do you unfreeze tracks before you render the final mix?
When i put vst Fx's on the master track itself, my CPU load goes so high, but if i create a sub-master track with all trakcs feeding it, and put the same FX on this sub-master track the CPU remains at minimum load. dont know why but it works on my old core i5(2012). hope it helps someone
Freezing a track saves the processed track to RAM?
The question remains, because many people will have great or top of the line hardware these days, how will Reaper handle high core count cpu's like for instance the 5900X which I own. Coming from Sonar Platinum, I really have this DAW on my radar, because of the honest price it asks for the DAW, yet still the colors are putting me off a bit, I know many people made themes and all, but after having worked in Sonar for years your eye must immidiately catch problems or certain clips you work on, and transients etc.. It is kind of hard to see.. Still I might try it out to see If i can make this work. I am curious about the multitreaded abilitie of this DAW, since many plugins are using just one core or tread, it is a life saver to have many core/treads in the system so each of em can have one. I'll give you an example, Between handbreak and a converter I own, when I use the converter to convert a 20 or something flac file into mp3, each core gets one song, and it will lightning fast convert them, on the other side, in video encoding, the cores are all bundles together and the video is encoded, that's why graphics card like the 7900XT which i also own are incredibly fast with AV1 for example, the GPU is one big matrix of cores and it will go through the video like butter.
Definitely try it.
reaper doesn't use gpu for rendering, even with video.
Hi! On my last podcast editting, i had one big problem that i havent seen before. My vsts automations (in my case, bypass automation) were not synched when rendering or freezing tracks. For example, i put an eq filtering the vocal for just one phrase of the host's speech. While monitoring the project, the timing of the automation was exactly where i wanted it to be. When rendering, the automation happened later, making the filter starting somewhere in the middle of the phrase and ending after the next phrase had already started. I realized that the PDC (plugin delay compensation) was being the problem, so when rendering, the compensation was being applied before the automation. I could save my workday by requesting a 32 samples blocksize for rendering, but the rendertime was huge. Is there some kind of setting which I'm missing?
I love the channel and learn a lot with you, thank you very much for sharing your knowledge with us!
wow I don't think I've ever run into that problem before. was it always with the same plugins? Feel free to send me a small project to test
@@TheREAPERBlog for now i won't be able to send you a project because im moving out to my new apartment, but soon i will try to replicate the problem and send it to you. On that day I've done some research on google and found some topics of people talking about similar problems, like this one (from 2017): forum.cockos.com/showthread.php?t=200750
Is there a general rule about how much CPU you can use before getting problems
Do you have a similar tip about video effects? I have literally JUST color correction plus brightness correction, and the playback is laggy like hell... Does Reaper not use GPU at all?
how can I swap the order of midi regions in different tempos, without messing up orchestration?
I had this problem for ages, I'm forced to write in very short fragments, and I can't find the solution
Reaper is great! But there is a BUT... How can I reduce recording latency when using plugins like Neural dsp fortin or Postive grid Bias. I’ve tried to do everything by the book to fix it. But nothing is helping. Any ideas?
Great tips, quick question: when you save the subproject for the 2nd time, does it overwrite the original file or does it create a new one? Asking because I usually hit save a bunch of times and wouldn't like to have too many files. Thank you
it replaces the the subproject .prox file.
🤯🤯🤯
Quick question: before you do any rendering or freezing, should you disable any effects on your Master Bus? Or does Reaper only consider what is on the track that you're rendering?
I usually have some EQ, Comp, Decapitator, and a Master Limiter on my master bus at all times and don't want them affecting the tracks themselves, but remembering to turn it off and on would be annoying haha.
For individual tracks and freeze it happens before the master chain.
In the render window there is an option to render tracks with master fx (selected items/tracks via master)
@@TheREAPERBlog thanks!
great content man! may i ask what mic youre using?
Lately I've been using a MOVO VSM-7, I have a review coming up.
@@TheREAPERBlog eyyy thanks for reply ma man! Ohhh first time i heard of it! Looks like the boya m 1000 a chinese mic. Checked the movo very similar might be the same but different brand. Thanks for reply and will eagerly waiting for future videos.
Thanks!
I got a problem.
I rendered a song, drums, 2 guitars, bass, keyboard, reverb FX.
The rendered song has some volumen drop-downs here and there. They are small, but it happens.
Is that a CPU / RAM problem?
Thanks!
How / what i that window you have to see the CPU usage? Does it also show RAM usage?
I had a quick scan through the comments but cant see any info on it.
View menu: performance meter
what theme is that?
how to create the red, thicker timeline?
So freezing the track does not write in the automated volume tweaks but it would print in changes in volume that you may have lowered in a split section of the original track, is that correct?
everything up to the end of the FX chain on the track. (pre-fader and pre-pan)
@@TheREAPERBlog Thanks 👍
Those highlighted borders around selected track in TCP is looking great. I would love to know how to make them.
Can I solve a doubt? Whenever I freeze tracks (to either mono or stereo), they loses a bit of quality of sound.
Greetings from Macaé, Brasil.
try and null test that. im pretty sure it does not.
What song is that??!!??!?!?
unfreezing is a great option, though the created audio files don't gete deleted afterwards, which might clutter your hard drive. in bigger projects it's always good to sometimes safe the project in a new folder and hit "copy" or "move audio files into project directory" and then delete the old cluttered project path. do you know of any better way of doing this?
Hmmm... There's a button in the file menu that says "clean current project directory". When clicked, it gives you a list of all the files it thinks aren't being used. You can choose to delete any number of them. I usually just trash them all. Haha
Must say this is unreal but someone please help me.
When I save a sub project it will be for the purposing of saving CPU in order to record with with less latency.
Once all my takes are done is there a way to make the subproject just be part of the main project as it was originally?
Any help is much appreciated 🙏
I have it 2048, and my CPU is 12% , and i have crackling sounds with 16GB ram I don't know what else to do any more I tried latencymon also everything seems fine
Clockspeed and IPC or singlethread perfomance bottleneck. Which CPU you have?
Device name Panas
Processor AMD Ryzen 7 5700U with Radeon Graphics 1.80 GHz
Installed RAM 16.0 GB (15.4 GB usable)
System type 64-bit operating system, x64-based processor
One problem, if i will use variant "sub progect" and will go to drums (in sub progect) - i cant hear other instruments from basic projects. Its very not comfortable. I hope in future Reaper will make update and "sub projects" will work correct)
right-click the project tab and you can see many options like running background projects and syncing projects
@@TheREAPERBlog Wow! First time hear! Very interested! Thanks! I dont see any info about this problem. I will try
Hey ! Thx for these advices ! I just think that your markers doesn't really impact the start and end of the renderering. Is there a way to do so, my project is pretty big and reaper also render long blank part of the track... :/
you can use markers named "=START" and "=END" to define the 'entire project' bounds.
or make a time selection and render with Time Selection bounds
or use regions
@@TheREAPERBlogThx for your quick answer! I should have precised that i'm trying to do it with the option "Move tracks to new subproject".I tried with both time selection and markers "=START" ans "=END" but it always renders all the track until there is no more items in the groupe / track. At the end of the render, in the subproject I can then move the markers "=START" "=END" that has been created automatically and save to reduce the size of the render. But it's weird that it doesn't works the first time, in the main project. And it's the same behavior in your example, when the file is rendered and automatically imported, it doesn't match to the position / lenght of markers. But maybe I just don't get how it's supposed to work?
not sure, I think tracks turned to subprojects always do full project.
Thanks for the video! if I froze the drum folder track and then mute the drum tracks would that work as well? I'm trying to leave Pro Tools for good and the ''make inactive tracks" doesn't seem to exist in Reaper, or am I missing something?
no idea about pro tools because they were the last to add freeze after every other daw.
I could take the kontakt track by itself and freeze multichannel. that would make a multichannel wav file, remove the fx and keep the routing to other tracks.
@@TheREAPERBlog Yes, PT is always running behind for certain things but when they implement something it works really well. Still, Reaper is lightyears ahead for some stuff. Thank you for your reply, I'll try the sub project and maybe it will work even better than PT. been learning a lot from your videos!
Nice drums. What's that?
Room sound Beau Burchell signature
Funny that made this video. Imma the only experiencing Reaper getting lil bit cpu heavy for the latest updates?
Record in 64 bit, mix in 2048 bitrate
Helix and T-Racks plugins eat way too much CPU... best way to ensure low CPU load is to always monitor it. try to use plugins with low CPU and low latency, and you'll be very happy always.
Hey dude great information. I noticed u rendered at 32 FP but your track is in 24 bit. Can you elaborate on this? TY
