Help with NYC Graphics

First of, I love new roads and NYC is beautiful. I like that the course’s terrain is nicely varied.

However, the combination of a normally popular Saturday, with a condensed map, and translucent roads so the poor old graphics card has to render riders ahead, behind, above and below made for a very laggy experience. The screen shot shows NYC with another, more typical day.

I know my mac isn’t a hot shot computer, but it is above the minimum specs. If I can’t world swap away from crowded maps for the sake of performance, could I get the options to turn off shadows like an Apple TV? Something to get the performance at least to the level of not distractingly slow.
