Mac: There's a lot you can do to improve gaming performance on the Mac, but a lot of it starts with benchmarking your current performance. Count It is a framerate counter that can help you figure out what's dragging your performance down, and what tweaks boost it. Count It works with just about any games you have installed on your Mac, whether you launch them from a tool like Steam, the Blizzard Launcher, GOG Galaxy or you have them installed directly (sadly, emulated games aren't supported). The video above is a brief tutorial to how the app works, and how you can use it to record your results. The app collects your framerate stats over time, displays them on a graph and helps you keep an eye on what background applications or other system tweaks improve or impact performance. It's also useful to help you figure out whether or not your Mac can even handle the game you're trying to play.
Count It is completely free, and you can grab it at the link below. You'll need to sign up via email to get the download, but aside from that, it's a quick install and easy to use.
