Until this year, I've never really gotten into Apple products, especially being a Zune fanboy. I recently got an iPad 3, as well as a new rMBP with 2.7/16/512 ssd. This thing is AMAZING! Although it will be a while before software devs make their programs high-dpi/"retina" compatible, I am finally glad to have a Macbook Pro. It's thinner and more powerful than any laptop I've owned. I previously had a first-gen HP ENVY 17, which I still love, but this thing blows it out of the water! Also, FWIW, it's not a fair comparison between laptops and desktops. Anyways, I just installed DayZ on my Win7 bootcamp partition, and it's running pretty great! I'm on my way out the door from work, so I'll have to get back to you on how high I can get settings before it's too laggy. I just tested 1600x900 with low shadows, no post processing, medium details, and it felt like 40-60fps in Cherno. I also need to install fraps. Edit- I installed fraps. This game runs quite well IMHO. 2880x1800 gave me a near-unplayable 20-25 fps, while 1920x1200 gave me 30-45; all tested while looking through a window in Cherno. Changing my interface down to 1920x1200 forced my game to change the 3D to 1280x800, and it was 45-65 FPS, without looking too bad. I think I'm going to play at 1920x1200 or 1600x1000 (or something in-between) rez, though. It looks great, runs smooth, and I'm sure you guys will enjoy it! Just tinker with setting 'til you find something you like! :D
