Hey,

My CPU isn't maxing out at 100%. It takes a while to render the comp when playing back on the timeline but the CPU or the RAM aren't maxing out. Do you know why this might be?

RTX 3090

AMD Ryzen 9 2950X 16-Core

63GB Ram

Kingston FURY Renegade PCIe 4.0 NVMe M.2 SSD 7,300/7,000MB/s read/write

Did Multi-Frame Rendering get disabled? Check Preferences > Memory & Performance to confirm.

Also, the default CPU utilization is 90% so you can still use your machine a bit while rendering.

Without any specifics about your composition and its contents we can't tell you much. That said, it sounds perfectly normal. AE in general is rarely ever on fuull burn, which has to do with how the internal processing works. Functions and effects that require linear processing will slow down things as will a ton of other factors. So for what it's worth, you just have to get used to it. Despite hardware acceleration and multiframe rendering the old addage applies: You can't kill AE with hardware. Understanding its inner workings and how to structure workflows is still just as important as a reasonably decent system.
