I've been playing The Sims 3 for a few weeks on my Vista partition of my laptop (a unibody Macbook Pro, the first 15 inch one in the range). When i bought it today, i thought i'd install it on OS X to make it easier to go on than having to sit through the 5 minute restart-into-windows operation. So here are a few screenshots: The Sims 3 running on Vista. The Sims 3 running on OS X (same laptop remember). And the graphics options on OS X (you'll just have to take my word for it that they're all on maximum settings on windows too). High Detail Lots is 'Adjust the number of nearby lots that render in high detail.' so nothing to do with these graphics here. I'm sure you'll agree the graphics on OS X are appalling when compared to the graphics on Vista. I'm tempted to sit through the 5 minute restart-to-vista process because those graphics are terrible.
