    I just got my first mac. Its the new base 21.5" iMac. I installed steam, then bought Portal.

    When it first loaded it defaulted to a number of things. I changed them all to the upper levels of performance, where it initially had lower levels. It also had a lower resolution than native.

    At first it seemed choppy until i turned on vsync. It then ran very smoothly.

    1. Why did it defualt to lower settings if it runs well on better settings?
    2. why did vsync on help?

    I just bought a 4GB 13" MBA, and I was trying to figure out which settings would be best for Portal 1 as well. It ran decently on the normal settings, but once I started moving the options around it improved a lot. I don't actually know what some of the options mean though, do any of you have a good primer for optimizing games?

    That totally helps explain why vsync helped.

    It would be really nice to understand what settings to adjust. Or when to disable vsync. I think that i get confused when i look at all of the settings options which ones to prioritize, and what settings i should push and what to back off of.

    Thank you for your explanation!

    Primer = starting guide, FAQ, how-to, etc. Primer like priming an engine to get it started.

    Thanks for the advice all, I'll try messing around with settings when I get home. And then once I finish the game, I'll do it again with Portal 2!

    First, thank you for all of your explanations and help. I really appreciate it and will fiddle with everything when i get home! I'll also try to look up how to measure FPS.

    The only other game i have right now on the mac is half life 2. When i installed steam it said i had already purchased it! That was pretty cool...i'd bought it way back in the day when it was first released for my old PC. I like that steam will let me play it again for free. Other than that I have nothing.

    For fps, hit esc: options:keyboard:advanced: then check enable dev console. After that go back to the game and hit the ~ button. Then type cl_showfps 2. This shows you an average fps.

    What's amnesia?? I've never heard of that! I'll have to check it out. I've played assassins creed on the ps3.

    I did the console FPS code posted. I was getting over 100 FPS. My settings are everything as high as it goes (at 1920x1080) except antialiasing which i have set at 4x and filtering mode which i have set at anistopic 4x.

    There was a lot of screen tearing. Before turning on v-sync i also tried upping the filtering and the problem was that there was a huge difference in FPS when i was looking through a portal or not, so i just left them at 4x and turned vsync on. It stays at 59 or 60 fps almost always now.

    Thanks for your help again! i gotta find that amnesia thing. is that on steam?

    Yup they really are quite good! I'm running at 2560x1440, everything set to max (even AA, which is pointless at such a high res!). Never dips below 60fps... even with portals everywhere and the multiplayer cam enabled.

    Valve make very well optimised games - Apple made a very powerful iMac!

    I got the game running very smoothly, but during the boss fight it got choppy and I had some audio issues, which was a pretty big disappointment (considering how important audio is to this game). Still, I was only replaying it as a refresher, so it's not a huge deal.

    Depends on the amount of RAM you have on your card.

    If he drops below 60 fps with vsync, it's going to drop to 30fps anyway.
