Sim racing guide • Updated August 2026
The right iRacing PC depends on the complete cockpit: one 1080p monitor, a high-refresh display, triple screens, or VR can place very different demands on the graphics card and processor.
Official iRacing system tiers
| Tier | CPU | Graphics | Memory |
|---|---|---|---|
| Minimum | 4-core CPU or better | Gaming GPU with at least 4GB dedicated memory | 16GB system RAM |
| Mid-range | 6-core CPU or better | Gaming GPU with at least 6GB dedicated memory | 16GB system RAM |
| High-end | 8-core CPU or better | Gaming GPU with at least 8GB dedicated memory | 32GB RAM or more |
iRacing also requires 64-bit Windows 10 or 11 and at least 25GB free storage, or 50GB for all cars and tracks.

Choose by display setup
Single 1080p monitor
The most approachable workload. Prioritize a stable CPU/GPU balance and enough performance for the desired refresh rate and field of view.
Triple monitors
Three displays multiply the rendered pixels and increase cabling and output requirements. Confirm the combined resolution and available graphics-card ports.
VR headset
Use both iRacing’s requirements and the headset maker’s GPU support list. Consistent frame delivery and connection compatibility are especially important.

Do the wheel and pedals change the PC requirement?
They do not add a large graphics workload, but the full rig can require multiple USB connections and stable device management. List the wheelbase, pedals, shifter, handbrake, button box, headset, and displays before finalizing port and cable needs. Do not assume a USB hub solves every high-power or latency-sensitive device issue.
Storage and network
Plan more than the bare 50GB all-content figure so Windows, updates, recordings, telemetry tools, and other games have room. A stable broadband connection matters for online racing; Wi-Fi 6 is included on current Gigatech systems, but a wired Ethernet connection is often preferable when the room supports it.
