Is there any way to have more than one batch render running?

I'd like to render out a few scenes made by a script I wrote, but the amount of objects causes each frame to take around 90% preparing and 10% processing, so my cpu is barely used up. I've looked around and seen you can queue up multiple renders, but I'd actually like to have multiple ones going at the same time to make it more efficient.

Is this possible at all?

Thanks

Of course you can do it. Just open a command line(windows) or a terminal then run the "render.exe " command. Do it for all scenes you would like to process.

You might want to double check that the Batch Render Options 'Render Threads' option is set to the number of threads your machine has. I have no idea WHY the default is still '2'. Sometimes I have to toss my preferences folder temporarily and it takes me a while to realize that a previously fast render is taking ages because it's only using two threads.

I thought the command line let you queue renders, but not pull of multiple ones at once? I've also attempted a command line render before, but couldn't get it working and gave up on it haha

And I have set it to use all cores lol, but the pre-processing of the scene is only single threaded, and with 200,000 objects, takes like forever to load each frame

Below is what the code does anyway, that's about halfway through an animation, and it branches out more later on, so that's probably only about 1/4 of the entire scene. The amount of cubes mean the renderer is running at 13% cpu most of the time, which is why I'd like to be able to set multiple ones going
