The render time started at about 14 hrs and after reaching that number the time remaining has now jumped to 53 hours. This carries over to Media Encoder of course. When there is insufficient RAM, data from RAM is temporarily stored in the cache and then re-read back into RAM - this slows down renders considerably.

Hence, as more frames are being rendered, there is less RAM available for processing. I've also tried setting particular to render with GPU streaming but to no avail. Its very likely that AE/Particular is not clearing/cleaning up RAM efficiently. I tried resetting particular entirely and using just one default emitter, and even then it renders well enough early on in the video but if I skip about 30 mins in my render time is severely reduced. But my issue is that the RAM Preview and Rendering is very slow when I add an audio spectrum with 2000 frequency bands and Trapcode Particular. I am still new to After Effects and i’m trying to figure things out. I am currently making an audio visualizer. I have 4 layer emitters generating particles at a rate of between 70 and 300/sec. Hello I have been fooling around in After Effects and I have been having a great time. Turns out particular is what's causing it but I can't quite grasp why. Here are the specifications of my laptop.

This computer is where the slow rendering happens. I had a lot of precomps that I prerendered out then imported back in as vids with alpha, and trimmed layers I didn't need which helped, but the render time was still incredibly high. Rendering in Adobe After Effects CC 2017 on my gaming laptop is too slow I have performed a test with two laptops and a desktop PC. I've been trying to render out a video that's 51 mins long and optimizing it where I can.
