The animations are similar to gif files. There is no pulsing whatsoever. I'd try downloading the game, then playing it. If it does pulse, then I'd have to say, there is no way to turn it off, since the animations are moving files. It almost sounds as if your video card is causing the issue with your refresh rate. You could toy with your refresh rate settings and maybe that will fix it for you. It almost sounds like you have a synch issue.
