CPU and GPU question

Nothing that follows affects the operability of MG3 whatsoever, so this is hardly a complaint — just perhaps a question for @JamO.

I’m wondering why there is such an increase in CPU and GPU usage when MG3 operates in the background (plugin hidden) compared to when it is in view? So I took the habit of hiding/closing the MG3 window whenever I don’t need to access its settings to preserve the CPU/GPU for other tasks.

I made this simple benchmark using the task manager to give you a comparison. This was tested on Windows 10 (minimal bloatware), i7-9700 @ 3GHz, 32GB RAM, and an NVIDIA GeForce GTX 1660 Ti (Studio drivers). I also compared it with Fender Studio Pro that I use and another DAW to determine whether this might be DAW-related.

What I noticed is that resizing the MG3 window makes quite a significant difference in how much the GPU is being taxed.

Perhaps I miss something critical in my setup ? Please let me know if it’s the case.

Here is mine, Windows 11, Reaper, a complex patch (with 3 synths and various effects), MG3 HEX and a very capable computer:

       16      Hidden    8      2
       16      Visible   10     13 

In my case the jump in GPU is kinda on the high side but still in line with other plugins that vary between 4%-10% so maybe there is some room for improvement.

Wow, it’s quite a difference from my setup. Looks like your computer looks like way faster than mine !

if you don’t use the system for gaming then it might be worth giving this a try:

i’m not recommending it based on experience, i haven’t tried it. but even with the studio drivers nvidia installs a bunch of stuff which isn’t necessary for music making.

Oh ? That’s interesting! I will look at it. Thanks !!

@kimyo WOW!!!, that has fixed my issue by a large margin. I am now down to 10-15% on the GPU after running the clean install option of the driver with NVCleanstall. CPU% looks like it remains unchanged.

Today, I learned something & I fixed something. What a relief ?!

Million thanks to suggesting this solution, really !! :slight_smile:

For DAW NVidia GPUs are problematic especially if you are looking to achieve low latency setups. I use an AMD RX6600 with everything disabled in the low noise mode (the GPU fan is basically always off)

Thanks @ElectroFuzz. I was not aware of this. This is new to me. Thanks for the tip that I will definitely look into when I am going to upgrade my computer.
