Question / Help Extreme Frame Skipping

I've been using OBS for a little while now on Twitch, while I don't really have a big following I would occasionally have friends watch and interact in chat. They all talked about lag issues with video freezing and audio not. I looked it up but dismissed the issue since all I found was different reasons why the viewers couldn't watch, not because the streamer was making a mistake. After looking more and another stream, I learned about the OBS log feeds that generate after each session. I checked mine to find that I was getting ~220% frame encoding skips. I don't understand this entirely, and I know it's not an internet issue (I run 90mbps up, 35mbps down). What could be wrong with my hardware?

I'm running an HP laptop, with AMD A8 (1.9GHz / Radeon HD Graphics)
I have 6Gb dedicated RAM as well (I've already been considering upgrading this)

(Lagged frames aren't an issue, I've only seen a max of 2% frames lagged after encoding)

Can you please provide the full log?

But just given the PC specs, that CPU is extremely weak. You're probably going to have to downscale the output to something like 480/560p to get anything watchable.

Here is the log for the whole stream/session; the section where I switch from scene "AFK" to "prestream" a lot is because I was setting up an overlay. The rest is stream stuff. I've been informed of OBS's stream optimization already so anything else helps.

Code:
22:51:40.235: Output 'simple_stream': Number of skipped frames due to encoding lag: 71148 (219.6%)
22:51:40.235: Output 'simple_stream': Number of lagged frames due to rendering lag/stalls: 637 (0.9%)

You will need to significantly downscale the output resolution. Try the smallest resolution in the list in Settings -> Video (for Output resolution) and see if that works. Your PC is very, very weak.

I've decided to save up and build a desktop, thank you for your assistance, I appreciate it.
