The official CS2 system requirements are a 64-bit Windows 10 install, four CPU threads, an Intel Core i5-750 or better, 8 GB of RAM, a DirectX 11 graphics card with at least 1 GB of VRAM and Shader Model 5.0 support, plus 85 GB of storage. That is the entire official list, because Valve never published recommended specs.
That gap matters more than it sounds. Those minimums date to a CPU from 2009. They tell you whether CS2 will launch, not whether it will hold a stable frame rate during a retake. Here are the real numbers, and what to actually buy on a budget.
Official CS2 system requirements
These come straight from the Steam store page.
- OS: Windows 10, 64-bit
- Processor: 4 hardware CPU threads, Intel Core i5-750 or higher
- Memory: 8 GB RAM
- Graphics: DirectX 11 compatible card with 1 GB of VRAM or more, Shader Model 5.0 support required
- DirectX: Version 11
- Storage: 85 GB available space
The storage figure is generous. The actual install sits closer to 60 GB, but Valve asks for headroom to handle updates and map additions.
One platform note. CS2 does not run on macOS. Valve dropped Mac support and offers Mac players a legacy CS:GO build instead. Windows and Linux are the supported platforms.
Why there are no official recommended specs
Valve lists only minimums on the Steam page. Every “recommended CS2 spec” you find elsewhere is a community target, not a Valve label.
This causes real confusion. People read recommended requirements for other games as meaning high settings at 60 fps. In Counter-Strike, competitive players run low settings on purpose, and 60 fps is nowhere near the goal.
That is why a checklist approach fails here. Meeting the minimum gets the game running. It does not stop your frames from collapsing during a full utility fight, which is the exact moment the round is decided.
Best budget specs for 144 fps
This is the realistic entry point for competitive play in 2026.
- CPU: AMD Ryzen 5 5600 or Intel Core i5-12400
- GPU: RTX 3050, RX 6600 or Intel Arc B580
- RAM: 16 GB DDR4 3200 MHz, dual channel
- Storage: NVMe SSD
- Monitor: 144 Hz
An RTX 3050 pushes close to 200 fps at 1080p on competitive settings. An RX 6600 clears 150 comfortably. The RTX 3060 remains the most common card on Steam and handles 144 Hz without complaint.
Notice the CPU is doing the heavy lifting in this build. A Ryzen 5 5600 paired with a modest GPU beats an old quad core paired with an expensive one, every time.
Stepping up to 240 Hz and beyond
If you are buying a higher refresh monitor, the money goes into the processor rather than the graphics card.
A Ryzen 5 9600X averages above 500 fps at 1080p competitive settings, with 1 percent lows near 260. That pins a 240 Hz panel cleanly.
The 3D V-Cache chips sit above that. A Ryzen 7 7800X3D holds 1 percent lows above 290. A 9800X3D holds above 350. Most top tier professionals run one of those two on AM5 with a tight DDR5-6000 kit.
An Intel Core i5-14600K lands around 240 for 1 percent lows, which is fine for 165 Hz and workable at 240 Hz.
On the GPU side, an RTX 5060 or RX 9060 XT is already enough to feed those frame rates at competitive settings.
Why CS2 is CPU-bound, not GPU-bound
Source 2 leans on the processor far more than the graphics card. Pros play at 1080p or 1280×960 on low settings, which removes almost all GPU load and leaves the CPU as the limiting factor.
The number that matters is your 1 percent lows, not your average frame rate. Peeker advantage lives there. An average of 400 fps means nothing if a smoke and molotov exchange drops you to 90 for half a second.
This is why players upgrade a graphics card, see barely any change, and conclude the game is badly optimised. The bottleneck was never the GPU.
RAM speed also matters more than usual. Enable XMP or DOCP in your BIOS, because running a DDR4-3200 kit at 2133 leaves real performance on the table.
Tips to get more FPS in CS2
Cap your frame rate slightly above your monitor refresh rate. Uncapped frames add heat and inconsistent frame pacing without helping.
Turn on NVIDIA Reflex Low Latency if your card supports it. It syncs CPU and GPU during rendering and shaves off input lag.
Drop Shader Detail, Particle Detail and Ambient Occlusion first. Particle Detail in particular saves frames during smoke and molotov chaos.
Set Windows to High Performance power mode and close background apps. CS2 is CPU-bound, so anything competing for processor time costs you frames.
Keep Model and Texture Detail at Medium rather than Low. Low can make player models harder to read against certain backgrounds.

Frequently asked questions about CS2 system requirements
Windows 10 64-bit, four CPU threads with an Intel Core i5-750 or better, 8 GB of RAM, a DirectX 11 card with 1 GB of VRAM and Shader Model 5.0, and 85 GB of storage.
No. Valve publishes only minimum specs on the Steam page, so every recommended build you see online is a community estimate.
Steam lists 85 GB. The actual install is closer to 60 GB, with the rest acting as headroom for updates.
No. Valve ended macOS support and offers a legacy CS:GO version instead. CS2 runs on Windows and Linux.
CPU, clearly. At competitive settings the graphics load is light, so your processor determines your frame rate and your 1 percent lows.
An RTX 3050, RX 6600 or Intel Arc B580 is enough at 1080p, provided you pair it with a reasonably modern CPU.
Final thoughts
The official CS2 system requirements are almost useless as a buying guide. They confirm the game will start on hardware from 2009 and say nothing about competitive play, which is what most people are actually asking about.
Build around the processor instead. A Ryzen 5 5600 with an RTX 3050 will feel better in a real match than an old CPU with a card costing three times as much. You can confirm the current official listing any time on the Counter-Strike 2 Steam page.
