Internet explorer problem with magnifize theme

hi,

well i uploaded my site a few months ago, lately i noticed a lot of bounce rate from users that have internet explorer so i tried it, when i saw the page the font of the titles of the post, pages and main links looked pixelated, like if you used wet paint to write it, looks awful, even the images in the galleries looked out of frame, and the site is soooo slow when scrolling down, in overall the site performance is insanely poor in internet explorer, i never saw that in any other web browser.
my site is http://www.tripandtraveldr.com

So i just wanted to know if you guys have any idea of my issue and we can work together to fix it

Thnx in advance.
