Justnick,

I just realised what you meant.
"Slower" as in rendering in the graffiti wall.
I totally forgot, I adjusted the skipping algorithm the other night to add greater detail at higher resolution, but have altered it for lower resolution.

When you said you don't change cpu mode it struck me that you must be using a lower screen resolution.

I have just been using it myself at lower resolution (testing cpu stuff) and realised it was slower.

I'll fix it next time I dive in, sorry about that.
