I'm looking for a solution to monitor the refresh rate of the OSX.
In several reviews like this one about the retina Macbook Pro by Anandtech they report actual fps to discuss the performance of scrolling in Safari in Lion vs Mountain Lion.
What tool are they using to monitor the fps? What similar tool like this can you recommend?
I love Borderlands.
It's an FPS with RPG roots, very stylish cell-shaded graphics. It's available in the Mac App Store, so no compatability issues if you run an OS recent enough to even hit the App Store...

Gearbox Software’s acclaimed sci-fi hit comes to the Mac, complete with all four Add-On packs. Borderlands Game of the Year Edition is a unique hybrid of first person shooter and role-playing game with a super sharp visual style and a compelling four player co-op mode.
Planet Pandora is a sparsely populated wasteland where the rule of law gets rewritten daily in the smoke of the last gun battle. Civilization consists of small outposts on the fringe of human influence, in an area called the Borderlands. Pandora’s one claim to fame is a mythical Vault supposedly packed with fantastic riches.
Fortune hunters, corrupt corporate mercenaries and lowlife hoodlums roam the landscape, searching under every grain of sand for the treasure. Since most intelligent life on Pandora has the occupation of Vault Hunter, society has gone to hell – making the outposts and outback areas more than just a little dangerous.
• Unique hybrid role playing shooter that combines frantic first-person shooting action with accessible role-playing character progression.
• Super sharp graphics style gives Borderlands a unique comic book come-to-life look.
• Co-op Frenzy – drop in and out with up to 4 player co-operative for a maniacal multiplayer experience.
• Millions of randomly generated guns! Choose your weapon from rocket-launching shotguns, enemy-torching revolvers, and tons more.
• Huge single-player game with four playable characters and serious replayability.
• Includes all four Add-On packs – The Zombie Island of Dr. Ned, Mad Moxxi’s Underdome Riot, The Secret Armory of General Knoxx, and Claptrap’s New Robot Revolution.
• Supports PS3 gamepads connected using Bluetooth®.
There is a command execsnoop that you can run in a terminal window. Like so:
sudo execsnoop -v
A more detailed log of all that is going on requires a bit of dtrace hacking, as you need to track the fork and _exit system calls as well.
Edited to add a bit of explanation: Processes don't “start” on a unix system. New processes are created by the fork system call, which results in the calling process being split into two (almost) identical processes. One (the parent) keeps its PID, while the other (the childe) given a new PID. The most common reason for a fork is for the child to exec a new program; it's this fork+exec combination that you most commonly think of as a new process starting up. This is why you need to track three system calls (fork, exec, _exit) for the complete view. But just tracking exec, as execsnoop will do, seems sufficient for your purposes.

The tool being used in the screen shot is "Quartz Debug"
It is part of Apple's free Graphics Tools for Xcode.
To get this app:
Running Quartz Debug should show the FPS meter. It has various options which allow tweaking of Quartz settings.
