Performance Worsening?
I used to be able to run Half-Life 2, the episodes and Portal at maximum graphics settings and still maintain a smooth 60 fps. However, for the last two weeks, the framerate has steadily been getting worse. I now have to lower the settings just to keep a playable framerate. Any idea why this would be?

Specs are:
OS: Ubuntu 12.04 64 bit, running Fluxbox with XFCE4-panel
Processor: AMD a8 3.2ghz processor
GPU: Radeon HD 7560d (part of the apu) and 6400m, with driver 3.12.
Memory: 12gb

is your computer getting hot?

I didn't notice any performance worsening. I assume this is

a) Something you did
b) Something Canonical did

There are a variety of sensors for Ubuntu. You might wanna check them out.

If you're getting hot: Remove any dust that accumulated on the heat-sinks, and if that doesn't help: go to computer shops and buy thermal paste. Google for how to remove and how to properly apply them.

I haven't made any changes aside from changing the background picture.

I doubt it's anything Canonical did recently, since the computer hasn't had internet connection since the beginning of January.

The problem is only with HL, or with other games too?
Yeap, it looks pretty much like overheating in CPU or GPU, or some weird hardware issue.
Do you have enough space on partitions? Also check steam's output and dmesg, they may show something interesting.

Enabled vsync maybe?

Disabling vsync only gives an average of 2 more fps.

I can't find any of the standard ones from ubuntu. Are they installed by default? Pardon my ignorance. I do have KDE-Plasma installed though. Maybe I should check some of the temp widgets.

Google "Ubuntu sensor" and you'll be presented with hundreds of ways to configure and monitor your temps :)

Then you have a CPU limit, which means you should look around CPU clock speed, voltage, performance profiles, CPU governor, overheating etc.

Probably it is indeed overheating and the CPU downclocking, as others guessed above.

The CPU temp is ranging between 80 and 120 degrees in KDE

Is it Celsius or Fahrenheit?

it will be Fahrenheit. @ 100°C the APU stop.
you can habe 2 problems.
1. your have RAM on conflict. how you get 12GB? a good system used 4, 8, 16 GB
2. the second grafik. 6400m??? a notebook hardware??? and the driver 3.12? do you mean 13.12???
for the apu ich would used ubuntu 13.10.
is your APU the AMD A8-5600K?
