TROUBLE SHOOTING PERFORMANCE

[teejco]

Built my first PC this year so please be patient with my beginner knowledge! (Let me know if more specs are needed) 

 

Basically got the PC working, got adobe installed, and im not sure why im still getting sub par playback performance / rendering. Cinebench is 9006, yet it still seems to struggle with relatively simple projects. 

 

Opened up task manager to see if I could find an issue and turns out im only using 30% - 50% CPU while running AE / rendering in AME. 

 

Really not sure what my next steps should be. Pretty sure my drivers are up to date, my AE RAM usage is maxed, and I have 400gb on my NVME drive for storage that I purge frequently. 

 

 

Any idea why im only getting 30% - 50% cpu usage? GPU also varies around 10% as well using Mercury Playback Engine GPU Acceleration (CUDA), is that normal as I know AE is not necessarily made for GPU rendering. 

 

 

CPU - Ryzen 9 3950x 3.5 GHz 16 core

MEMORY - GSKILL Ripjaws V 32 (2x16GB) ddr4-3600 

GPU - MSI GeForce RTX 2080 Ti GB Gaming x Trio 

Storage - Sabrent Rocket 1tb NVME + Segate BarraCuda 2tb SSD

 

Also for reference -

Whether there is a problem or not, or where, is a matter of what "sub par" means. It could just be a case of expectations vs. reality.

Because After Effects doesn't use that many cores. It probably is using a few cores to their maximum capacity, but since you have 16 of them, that amounts to 30-50% of your CPU.

See for example: https://www.pugetsystems.com/labs/articles/After-Effects-CC-2019-CPU-Roundup-Intel-vs-AMD-vs-Mac-1297/

8-core chips are at the top because AE doesn't scale past that, and the higher core-count CPUs are clocked lower to accommodate those extra cores in a limited power budget.

You can run their benchmark; I assume you should get something North of 800 or thereabouts, maybe more if I underestimate the impact of IPC gains and cache.

If you get something significantly lower, then you may have something to toubleshoot.
