Question

AE only using 25 percent of my CPU

I would like to get faster renders.  I have noticed that after effects is only using 25 percent of my cpu.  Is there any way to crank that all the way up to 100 percent like Premier does automatically?

    Has anyone found a fix to this or are you just going to keep glorifying adobes garbage product that they dont help you with whatsoever no reason it should take 10 hours to render something that is 10 seconds long several other software have a high render with 100x more things in the scenes you get this effect WITHOUT even using 3D stuff... What kind of ripoff is this where yall cant fix your product and charge this much for a product that wont even finish the rendering process without failing on small projects. FIX IT

    this is realy frustrating am usung after effects v22.0.1.2 and my processeor doesnt go more that 50% and 20 most of the time my ram is 77% pls what can i do to fix this its not fair am tired an i have just 12 hours to finish this project

    Did you ever figure out what was the issue ? Cause I have a RTX 3080 , 32 GB of RAM and a I9 9900k and im still struggling in after effects.

    THe only way ive managed to make use my quadcore with AE is to use gridiron's nucleo pro 2.

    FYI render multiple frames doesnt do squat, adobe doesnt have any clue what its doing when it comes to performance, all they can do is add bells and whistles and try to keep it all in one piece.

    Nope. In addition to what was said before, you have to consider that many effects simply aren't that computationally intense. Even applying particle systems with several thousand particles is a walk in the park on modern computers. Furthermore, there is a difference whether an effect requires a lot of temporal information and thus needs to calculate several frames at once or if it's a "dumb" effect that just modifies color values or gnerates elements. It's really more a matter of how they are combined. Also note, that several functions and effects only use conventional multithreading, meaning that by themselves they will use 2 cores at most.

    HI

    I have just upgraded to an i7 intel from a q6600 quad core pc.

    Im seeing only 16% cpu usage and my renders are taking the same amount of time on the new pc as the old.

    So am I right in thinking that there was no point in upgrading my pc if AE cant use any more of the processor?

    I find this hard to believe, especially considering my RAM and hard drives are faster. My ram is now DDR3 compared to DDR1 and my hard drives are being accessed at less than 1mb/sec. So I dont see any bottlenecks there!

    You've told us very little about your setup, such as how much RAM you have, whether you're using Render Multiple Frames Simultaneously multiprocessing, what operating system you're using, etc.

    Please read this page ("Memory & Multiprocessing preferences") and this page ("Performance tip: Don't starve your software of RAM") to learn about how memory settings can affect performance.

    There are a lot of ways to get faster rendering. See the "Improve performance" section of After Effects Help.

    Note that you won't always see your CPU being maxed out. Maybe the bottleneck in processing is your hard disk, your RAM, et cetera. The rendering of some compositions is memory-intensive, such as when you are working with very large background plates that are several thousands of pixels tall and wide. The rendering of some compositions is bandwidth-intensive (I/O-intensive), such as when you are working with many source files, especially if they are not served by a fast, local, dedicated disk drive. The rendering of some compositions is processor-intensive .

    Thanks I'll look into that.
