Bitching about shot animations with this game is futile and really there isn't anything WGT can do about it, it's the game itself.
Flash does not handle any type of even remotely high-res or even standard-res image rendering/serving. Never has, it was never designed to do so. It's a vector animation tool. I've been working with it since in was a plugin for Director way way back.
Track any website which is using Flash as it's primary build and you'll usually find either one of two things. Large/poorly optimized images being served up or bad audio. This 'game' has both. This isn't an executable game, it's a Flash based game in a browser. The fact that it plays at all is actually quite a feat, that it plays as poorly as it does is no surprise at all. Wrong platform for the job. Not even taking into consideration what vem is doing to it.
The only thing that would 'fix' it is if they spent massive amounts of money and built a totally 'private Internet' dedicated to it, even then it would still have issues.
You want to see what's going on with the game, run Scout against it. TM just shows your machine.
