CS2 says your graphics card is not supported: what to do
Why CS2 reports an unsupported GPU or will not start on an old PC: DirectX 11 and Shader Model 5.0 requirements, integrated graphics and drivers.
If CS2 shows an unsupported GPU error or closes right away on an old PC, the cause is usually the graphics requirements.
📌 What the GPU needs
DirectX 11 and Shader Model 5.0 support.
At least 1 GB of VRAM.
An up-to-date driver from the manufacturer.
🔧 Check which GPU is used
Press Win + R, type
dxdiagand open the "Display" tab.If it lists integrated graphics (Intel UHD, etc.) while you have a dedicated card, assign CS2 to it in Settings → System → Display → Graphics.
Plug your monitor into the graphics card, not the motherboard.
🖥️ Update the driver
An outdated driver can report the wrong capabilities to the game. Install the latest version from NVIDIA, AMD or Intel.
🎯 If the card really is old
Try the
-vulkanlaunch option — it sometimes helps on older AMD cards.If the card does not support DirectX 11 at all, the only fix is replacing the GPU.
⚠️ Tip
Before buying a new GPU, check your power supply wattage and that it has the required power connectors.
