20% CPU usage during rendering normal?

Hello,

During rendering my fx 8350 only runs at 20% usage. 5 out of the 8 cores are working while 3 stay at idle. I would think rendering would consume a lot more cpu usage than just 20%. Rendering times also seem to be somewhat longer than I would expect. I usually use H.264 and enable hardware excelleration.

I just want to know if this is normal or if powerdirector isn't utilizing the full potential of my cpu.



Thanks!

Hmm that does concern me that something may not be set correctly. I have multicore threading enabled on pd13 and I've updated all my drivers to the latest. During rendering my computer behaves like it isn't working at all and is exceptionally fast. This shouldn't be the case, I would think it would crawl as rendering should drag it down.

From what I can tell it must be something to do with hardware acceleration enabled. Maybe instead of using 100% of cpu and adding some of the work to the gpu, it shares the workout evenly?

Edit - I just ran a rendering test with fast video rendering technology disabled and it didn't change anything, still low cpu usage. I tried rendering in mpeg2 and avi and still same low cpu usage. Also tried disabling hardware decoding and hardware cl and still no change.

Any ideas?
