Question / Help FPS Drops, Avg time to render spikes, skipped due to encoding increases

I dropped the video output to 1280x720 -- this improved the situation a lot.
I then changed the downscale filter to Lanczos (it was Bilinear) -- this made little difference.
My rate control is CRF 15, and I moved the CPU to veryfast.

Would adding memory help?
I'm just using the on-board video -- would a high-end graphics card help.

Note that I'm not streaming anything CPU intensive, so I'm surprised this is a problem at all.
The problem only happens then there is a lot of activity on the screen.

At times the CPU usage hits 65% or higher, and I've had a few temperature related (my guess) computer lockups.

I also set the OBS processor priority to high but this didn't seem to help much.
Would setting the processor affinity make a positive difference?

You're going to need more than an Intel 4600 to render frames, take a look at your GPU usage when OBS is running. Rendering lag is caused by lack of GPU resources to render the frames for the encoder.

Thanks
It looks like I'm in the market for a graphics card.

Can you suggest a sight that provides a comparison of the various graphics processors when used with OBS?

The OBS minimum hardware recommendation did not mention graphics cards.

Will adding RAM to the computer help OBS?

Will a video card with more RAM help with rendering?

I used Open Hardware Monitor to watch my CPU, Fan speed and temperature, and Task manager to watch the GPU.

Very instructive.

What I am streaming is very low intensity, but apparently not low enough...
