Why Do You Have Low FPS in CS2?

With the transition to the Source 2 engine, CS2 has improved graphics but also increased system requirements. FPS drops are common, especially on older systems. In this guide, we will explain how to increase performance by 40% without sacrificing too much visual quality.

1. Best Launch Options

Right-click CS2 in your Steam Library -> Properties -> General -> Launch Options:

-high -threads 8 -freq 144 -novid -nojoy

-high: Sets high CPU priority.
-threads X: Set to your CPU core count (e.g., 4, 6, 8).
-novid: Skips the intro video.

2. Critical Video Settings

Make sure to disable these in the settings menu:

Ambient Occlusion: Disabled (Consumes high FPS)
Particle Detail: Low (Prevents drops in smoke/molotovs)
FidelityFX Super Resolution: Performance (Slight blur, huge FPS gain)

3. Console Commands

Open console (~) and type:

fps_max 0
cl_forcepreload 1
