HOW DOES THE FPS TEST WORK?

 You must first click the Download button. Click the Download with Mac or Download with Windows buttons to start the download if you're using a Mac or Windows computer, respectively.

Install it on your device after that. After installation, you must register or log in. The GPU and CPU are being monitored here. Go to settings and select overlay. A few panels (FPS, RAM, CPU, GPU, etc.) or an online FPS meter will appear.

For network and system timings, there is only one choice, however it is not required. You can choose the size and transparency of the statistics below. I've chosen a huge size with a 50% opacity.
