Can my old PC run League of Legends?

Possibly. The minimum is an Intel Core i3-530 or AMD A6-3650, 2 GB RAM and a DirectX 11 graphics card, on Windows 10 (build 19041+) or Windows 11. Expect low settings at that level.

Does League of Legends run on Mac?

Yes. Riot lists an Apple M1 chip, 8 GB of unified memory and macOS 12. Intel Macs may still run it, but support focuses on Apple Silicon.

Does it work on Linux or Steam Deck?

No. Riot says Linux, SteamOS and Bazzite are not supported, and Riot cannot help with problems on them.

Do I need TPM 2.0 for League of Legends?

On Windows 11, yes. Riot lists TPM 2.0 as required there. Windows 10 does not need it, but it must be build 19041 or newer.

Why is the Play button greyed out?

Most often your graphics card or driver does not support DirectX 11 on Windows (or Metal on Mac). Update the driver first, then check dxdiag.

League of Legends System Requirements for PC and Mac (2026)

League of Legends runs on a wide range of PCs, but the rules changed in recent years: you now need DirectX 11 on Windows, a recent Windows 10 build, and TPM 2.0 on Windows 11. Riot lists minimum and recommended specs on its support site. We checked that page on October 10, 2026. Specs can change, so look at Riot's page if something fails.

Key takeaways

Windows needs 64-bit Windows 10 (build 19041 or later) or Windows 11.
Your graphics card must support DirectX 11. If not, the Play button is greyed out.
Windows 11 needs TPM 2.0 turned on.
Mac support is listed for Apple M1 chips and newer, with macOS 12.
Linux, SteamOS and Bazzite are not supported. Neither are ARM processors on Windows.

Windows specs

	Minimum	Recommended
CPU	Intel Core i3-530 or AMD A6-3650	Intel Core i5-8250 or AMD Ryzen 3 1200
GPU	GeForce 400 series, Radeon HD 6570 or Intel HD 4600 (DirectX 11)	GeForce 560, Radeon HD 6950 or Intel UHD 630
RAM	2 GB	4 GB
Video memory	1 GB	2 GB
Storage	16 GB (HDD)	16 GB (SSD)
Windows	Windows 10 build 19041+ or Windows 11	Windows 11
Settings	Low, 1024x768	High, 1920x1080

Riot lists only retail editions of Windows. Enterprise and Server editions are not supported. Windows 11 needs TPM 2.0 enabled. Riot also warns that meeting only the minimum can still give you performance problems, so aim above it if you can.

Mac specs

Riot lists the same hardware for minimum and recommended: an Apple M1 chip, a Metal-capable GPU, 8 GB of unified memory, 40 GB of storage and macOS 12. Only the graphics setting changes (Low or High, both at 1680x1050). Riot's page also says Intel Macs can still run the game, but support focuses on Apple Silicon, and problems that only affect Intel Macs may not be investigated. The page is not fully consistent here, so if you have an Intel Mac, expect that it may work but may not be fixed if it breaks.

What do the numbers mean in real play?

The minimum list targets low settings at a small screen size. That is enough to play, but team fights with many effects can drop your frame rate. The recommended list is closer to a smooth experience at 1080p with high settings. An SSD helps the game load faster and cuts the time spent staring at the loading screen, although the game itself does not need much space (16 GB on Windows, 40 GB on Mac).

Internet matters just as much as hardware. LoL sends small packets often, so stable ping is better than a high download speed. If you can, use a cable instead of Wi-Fi.

How to check your PC in two minutes

Press the Windows key, type "dxdiag" and press Enter. The first tab shows your CPU, RAM and Windows version. The Display tab shows your graphics card and DirectX feature levels.
Open Settings, then System, then About, to see the exact Windows build. You need build 19041 or later on Windows 10.
On Windows 11, press Windows+R, type "tpm.msc" and press Enter. It tells you if a TPM 2.0 chip is ready.
Compare what you see with the table above. If you pass the recommended column, you can play comfortably at 1080p.

Laptops, handhelds and cloud play

Many gaming laptops are far above the list, but thin office laptops with older Intel graphics sit near the minimum. They can run the game, but expect low settings and dips in big fights. Keep the laptop plugged in and set the power mode to high performance, because battery mode often cuts frame rate by a lot. Handheld PCs that run regular Windows can work, but handhelds that run SteamOS do not, because Riot does not support that system. Cloud gaming services are not covered on Riot's page either, so we cannot promise they will work.

How to install

Open the official download page and choose the Windows or Mac installer.
Run the installer and sign in with a Riot Account, or create one.
Let the game finish downloading and updating, then press Play.
Open settings and check that the resolution matches your monitor.

Fixing common problems

Play button greyed out: Since patch 25.21, Riot enforces DirectX 11 on Windows and Metal on Mac. Update your graphics driver, and check support with the DirectX Diagnostic Tool (dxdiag).
Error VAN 9004: You are on a Windows 10 build older than 19041. Update Windows.
Low frame rate: Close extra apps, lower shadows and effects, and update your graphics driver.
Very weak PC: Riot offers a MinConfig fix on its support page that loads the lowest settings. It overwrites your current in-game settings, so use it only if you need it.

Common mistakes

Buying hardware before checking if Windows 11 and TPM are already fine.
Installing on Linux or Steam Deck and expecting support. Riot does not support it.
Downloading the client from a third-party site.
