As a game developer, I work hard to try and make my games run at as high a framerate as possible, which invariably means optimizing my code in every way possible, trying to squeeze out that extra frame or two per second that will make all the difference in the user experience.
That’s why I find it quite frustrating when a game (so lovingly optimized) is running on the same page as some poorly-coded, graphically intense banner ad which uses tons of video and graphics processing and essentially just sits there, completely useless. This happened to me today while trying to play Fancy Pants world 2. This ad (the one with a wizard shooting fire or something like that), completely sucked up all the bandwidth— FP was forced by the browser to share processing with this pile of crap ad, which was probably coded by some intern somewhere, and it could barely even run.
As a developer I find this sickening and say to these so-called Flash designers who create monstrosities like that one: Nobody is impressed by your ostentatious use of Flash video and fancy gradients, so just give it a rest and make an ad that doesn’t crash the content that it’s supposed to be sponsoring.
