Just tried the Mac version of ToMI for the first time on my mid 2009 MBP (GF 9400M) and OS X 10.6.5.
I fist noticed that the image is very blurry even though I was using the native resolution 1280x800 and the highest detail setting. After fiddling around with the detail setting, I found out that the blurriness was gone on detail level 6 or below. The funny thing is that when I restart the game, the blurry image is back regardless of the detail level. Then I have to toggle the detail level for example 6->5->6 to get rid of the effect again.
Anyone else ever experienced this before? The game runs fine on Bootcamp Win7 with the same computer.
