CS2 System Requirements

Windows minimum requirements

Note the CPU line carefully: the requirement is four hardware threads, and the i5 750 is given as an example of a part that clears the bar, not as a floor in itself. A modern dual-core with hyperthreading technically satisfies the thread count.

SteamOS & Linux minimum requirements

Valve lists a separate block for Linux, and it differs from the Windows one in the graphics row:

The Vulkan extension callout is the practically important line. VK_EXT_graphics_pipeline_library is what lets the driver compile shaders incrementally rather than stalling; without it, Linux players tend to hit the shader-compilation stutter described in our CS2 stuttering fix.

There is no official recommended spec

Valve's store page has a minimum column and nothing else — for Windows and for Linux alike. If a site shows you a tidy "CS2 recommended requirements" table with a specific GPU and CPU in it, that table is editorial guesswork presented as a manufacturer figure.

That gap is genuinely awkward, because the minimum spec answers "will it launch?" and almost nobody is asking that. What people want to know is what it takes to hold a frame rate above their monitor's refresh in a smoke-heavy retake, and Valve has never published a number for it. The honest answer is that it depends on your resolution and settings far more than on any single component — which is what our FPS optimization guide and video settings guide are for.

Platforms Valve dropped

In October 2023, shortly after CS2 replaced CS:GO, Valve ended support for three things at once: macOS, DirectX 9, and 32-bit Windows. Valve's stated reason was that those users combined accounted for under one percent of active CS:GO players. Affected players were pointed at a legacy CS:GO build, and support for that build ended on 1 January 2024.

This is why the requirements above list no macOS column at all. CS2 targets 64-bit Windows and Linux only.

• Mac owners: there is no native client and no supported workaround inside Steam — see Can you play CS2 on Mac? for what actually works and what it costs you in performance.
• Console owners: CS2 has never shipped on Xbox or PlayStation. Our Is CS2 on console? page covers the one cloud-streaming route that functions.

Meeting the minimum vs actually playing well

Clearing the spec sheet gets you into a server. Three things tend to decide whether the game feels good after that, and none of them appear in Valve's table:

• Frame pacing, not average FPS. A stable 120 feels better than an average of 200 that collapses during executes. Check frame times rather than the headline number — how to show FPS in CS2 covers the readouts that expose this.
• Storage type. The 85 GB figure says nothing about speed, but shader cache and map loads are disk-bound, and CS2 rebuilds shader caches after driver updates.
• Settings, not silicon. Resolution and the handful of genuinely expensive video options move frame rate far more than the difference between two adjacent GPU tiers.

If you are already installed and the game runs badly, start with CS2 FPS boost rather than a hardware upgrade — most low-FPS reports resolve in settings.
