I created modified version of the “CS:GO Benchmark Script” that runs on de_ancient and measures your ingame performance.
To download the script head over to the github page and download the zip.
- Click on the green button named “Code” and then click on “Download ZIP
- Move the “csgo” folder from the ZIP to the default CSGO location on your drive.
- Launch the game and type in console “map de_ancient”
- When the map loads type “exec benchmark” and then type “benchmark”
- Wait 1min for the results to come up
Here is a video installation of the script for some more help.
