Question / Help OBS Taking a lot of resources

So I use OBS as opposed to xsplit because OBS is lighter running and I have a crappy processor. Typically it takes 35-40% of my CPU as opposed to Xsplit taking 60-70%. I tried streaming today however and OBS was taking 65-70% of my CPU. This is the first time I've streamed since installing the new version so I am assuming that is the cause, but I am unsure. Did OBS make a change that would cause this type of issue? It makes it very difficult to stream at times.

Depending on how old a revision you are coming up from, some of the much older versions were accidentally skipping a lot of the work they were supposed to be doing, which has been rectified in the last few revisions. We'd really need to see a full live log though to get more information about any bottlenecks or hardware issues.

Ah, you have a dual core CPU...alas. Dual core CPUs perform very badly when streaming.

Lower your FPS to 25, downscale your resolution by 1.25 or 1.5, and change your x264 preset to superfast or ultrafast, and see if that helps at all.

I think it was the FPS that caused the issue. I normally had it set to 25, didn't realize it was 30. Not sure if that was the update or if it had been that way since I formatted my hard drive and just streamed so infrequently that I didn't notice. Thanks for the help either way.
