macOS and 4K and fun ....

I'm breaking in a new Samsung 4K monitor, and wanted to check my Frames Per Second (FPS).

Thankfully, Apple have a tool for that ....

I went to developer.apple.com specifically here -> https://developer.apple.com/download/more/

and chose Additional Tools for Xcode 11.4

Amongst other tools, we have Quartz Debug

This includes a Frame Meter: -

Via the Window menu: -

So I'm getting around 30 FPS

The Mac is connected via an Anker USB-C hub 

I'm going to tinker with other options, including USB-C to HDMI and/or USB-C to DisplayPort cables .....

What fun!
