OSRS system requirements 2026: recommended specs for Windows, Mac, Android and iOS
OSRS is famously light, but the 2026 recommended specs give you comfortable headroom: on Windows, Windows 10 64-bit or later with an Intel i3-6100-class CPU (or AMD 2.4 GHz+), a GeForce GTX 600-series-class GPU (or Intel UHD 610), 8 GB RAM and at least 200 MB of free storage, with OpenGL 4.4 and Vulkan 1.1 support. On macOS you want macOS 11 (Big Sur) or later with an M1 chip and 4 GB RAM. On Android, Android Pie 9.0 or later with 4 GB RAM; on iOS, iOS 13 or later with 3 GB RAM. Both mobile platforms need about 2 GB of free storage. In practice OSRS runs on far weaker machines — a decade-old office laptop can often play it — but the official Desktop/Mobile clients, RuneLite and HDOS all benefit from meeting the recommended numbers, especially if you use GPU-heavy plugins.
Key takeaways
- Windows recommended: Win 10 64-bit+, i3-6100-class CPU, GTX 600-class GPU, 8 GB RAM, 200 MB storage, OpenGL 4.4 + Vulkan 1.1.
- macOS recommended: Big Sur (11)+ with an M1 chip and 4 GB RAM.
- Android recommended: Pie 9.0+ with 4 GB RAM; iOS recommended: iOS 13+ with 3 GB RAM; ~2 GB storage on mobile.
- In practice OSRS runs on much weaker hardware — the game is famously playable on old laptops.
- RuneLite and HDOS add overhead; the GPU plugin and HDOS need a real GPU, while vanilla clients run on almost anything.
- Performance tips: fixed mode, low detail, GPU plugin for resizable, limit plugins, and cap the frame rate.
The official recommended requirements
Jagex publishes recommended system requirements per platform, and in 2026 they look like this. On Windows: Windows 10 or later (64-bit), an Intel i3-6100 or AMD CPU at 2.4 GHz or faster, a GeForce GTX 600-series, AMD Radeon R7 260 or Intel UHD Graphics 610 GPU, 8 GB of RAM, at least 200 MB of free storage, and OpenGL 4.4 plus Vulkan 1.1 support.
On macOS the recommendation is macOS 11 (Big Sur) or later with an M1 chip, 4 GB of RAM and at least 2 GB of free storage. These numbers matter more now that the Jagex Launcher has native macOS and Linux builds.
For mobile, Android needs Pie 9.0 or above with 4 GB RAM, and iOS needs iOS 13 or later with 3 GB RAM; both want about 2 GB of free storage. The official mobile client is the supported way to play on phones, though RuneLite-style add-ons are desktop-only.
The low-end reality: OSRS on weak hardware
The recommended specs are for comfort, not survival. OSRS's engine is old enough that the vanilla client runs on hardware well below these numbers — plenty of players raid and skill on decade-old office laptops and budget Chromebook-class machines.
What actually matters on low-end machines: the client version and the renderer. The official client's fixed-mode and low-detail options dramatically cut GPU load, and the game's tick-based rendering is far more forgiving than modern MMOs.
The honest guideline: if your machine can open a modern browser and watch a 1080p video without stuttering, it can almost certainly run OSRS. The recommended specs only become important when you add GPU-accelerated plugins, HD packs, or play on a high-resolution resizable window.
Client overhead: RuneLite, HDOS and the launcher
The official desktop client and the mobile client are the lightest options. Third-party clients change the equation: RuneLite is still modest in vanilla mode, but the GPU plugin moves rendering to your graphics card and rewards a real GPU — on integrated graphics it can actually hurt performance.
HDOS is the heavy one: it re-renders the game in HD and genuinely needs a dedicated GPU and the recommended RAM. If your machine only just meets the minimum, HDOS will likely stutter.
The Jagex Launcher itself is light, but remember it now ships for Windows, macOS and Linux, and the Linux build (native since July 2026) has its own set of dependencies — check our Linux installation guide for the details.
Getting more FPS on any machine
Start with the display settings: fixed mode is the single biggest win on weak hardware, and low detail removes most visual effects. If you want a resizable window, enable the GPU plugin (RuneLite) rather than relying on the software renderer.
Reduce the load: disable plugins you don't use, lower the draw distance, and cap the frame rate — OSRS is tick-based, so 50 FPS is plenty and saving the GPU keeps your laptop cool and your battery alive.
On mobile, keep the client updated, avoid running heavy apps in the background, and use the in-client FPS settings to balance smoothness and battery. If the client feels laggy on an old phone, the mobile client's low-power mode helps.
Questions players ask
What are the minimum requirements to run OSRS?+
Officially Jagex publishes recommended specs, but in practice OSRS runs on very weak hardware — the vanilla client works on machines that can browse the web and stream video. The recommended numbers are for comfortable play with plugins.
Can my laptop run OSRS?+
Almost certainly yes if it can run a modern browser. Use fixed mode and low detail on weak hardware, and only consider the recommended specs for GPU-heavy plugins or HDOS.
What specs do I need for RuneLite's GPU plugin?+
A real dedicated GPU (GTX 600-series class or better) is recommended — on integrated graphics the GPU plugin can hurt more than it helps.
What are the OSRS mobile requirements?+
Android Pie 9.0 or later with 4 GB RAM, or iOS 13 or later with 3 GB RAM; both need about 2 GB of free storage.
Does HDOS need a good PC?+
Yes — HDOS re-renders the game in HD and needs a dedicated GPU plus the recommended RAM to run smoothly.
