Hi everyone,

I used to use OBS to record localy (no online streaming service) with my i5 2500k and I've never had problem.
Today I changed my cpu for a i7 4770k, and now when I record, OBS use all available CPU and my framerate drops until the game is unplayable.

Here is the log of my last test

EDIT:

Okay, wait, your CPU is a haswell, latest intel. Yet why in gods name is it reporting only 2 cores available? Sorry I edited this message, I'm totally baffled here.

Yes, sorry about that, xeiz in chat just said to me, "WTF Jim are you crazy? That's a haswell", I totally glanced over your model of CPU. Are you using any utilities to cut cores or something? Because it's only reporting 2 cores and 4 threads. Which -would- be the problem, but that shouldn't be happening.

Did you change anything in your bios ? Maybe they are deactivated, though this wouldnt just happen by default.

Ok it was because of msconfig, it was set to 4 processors, maybe it took 4 threads and not 4 cores. I deactivated it and my 4cores/8threads are back !

No more problems with recording ;) Thank you guys to pointed it out to me.

Glad we could help. Continuing on with only half of your CPU available to you would have been rather bad
