why is my cpu usage so high?

[lord of mush]

so I'm rendering a video with Vegas Pro 13 and using my cuda with my 970 ftw. my cpu is using 100%of all 4 cores, and I don't know why... any help, and tips for rendering are also appreciated.

thanks, Mush.

It renders the video with the gpu, and encodes with the cpu.

rendering uses your cpu to render the frames, so it goes faster if it uses 100% of your cpu and generally speaking people want their rendering to be done as fast as possible

so its not necessarily bad? I know it goes faster I just don't wanna f up my baby lol I just built this thing....

It's not a bad thing, temperatures above 85-90c are a bad thing, 100% cpu usage isn't bad

if you just build it your fine. if its like 5 years old then worry about it running at 100%

The cpu is not going to overheat. if it does get to a certain temperature it will thermal throttle and slow down

nope, that good. My 970/xeon is running sometimes days at 100% while rendering with blender. as long as they cool, this isn't a problem

with my asus fan control widget set to full speed so they are running temps in the 70s

thanks guys

well i tried running at 100% with all my fans turned off, it thermal throttled at 99c, not a very nice temperature for your cpu

From what I know, Vegas Pro 13 can only use CUDA acceleration on Fermi type card (4xx - 5xx).
Kepler's and Maxwell's are not actually accelerating anything.

why would you turn your fans off.

for silence ofc
and i've turned off all my casefans because they make noise and my cpu does fine without them  (not going above 75c when putting it under a continuous 100% load)

A bit late, but here's a tip:

 

If you want to use your PC whilst you are rendering (I can play BF4 on ultra whilst rendering and still be fine, but it depends), then you can:

- Open Task Manager

- Go to the "Details" tab

- Find Sony Vegas

- Right click it --> set priority --> Below Normal OR Low

 

This makes sure that processing of other applications is done first and then resources are given to the rendering program for every clock cycle. This will not slow you down significantly during browsing, but may do so during gaming.

thanks I wasn't planning on playing games and render, but ill keep that in mind
