Counter-Strike Source is over two decades old at this point, but the classic shooter still attracts tens of thousands of players daily on Steam. The game arrived at a key moment for the franchise, and while many still just wanted to play CS 1.6 instead, Counter-Strike Source became very popular in its own right in the years to come. Because of its age, the CS Source system requirements are very reasonable, and most will have no trouble running the game really smoothly.
Here, you’ll find all the CS Source system requirements with both minimum and recommended specs.
| CS Source Minimum System Requirements | CS Source Recommended System Requirements | |
|---|---|---|

Most modern systems will be able to handle the Counter-Strike Source system requirements without much of an issue. This means those who want to play CS Source online with friends should be good to do so, although do make sure you meet those requirements if you know you’re playing on a particularly low-spec machine.

Even if you meet the CS Source system requirements and are still having performance issues, do make sure to tweak the graphics settings. The Source engine scales very well on weaker hardware, so you should be able to improve your FPS fairly easily.
