Zwift is a massively multiplayer online game. And just like you wouldn't expect to win a road race with a beach cruiser, Zwift won't run well on an old computer.
Our minimum requirements, recommended, and extreme specs are all on our website so you can compare your computer against those.
Still not sure how you measure up?
The non-technical answer:
If you have a PC or Mac computer built in the last 3 years, you can probably run the game - but you'll do best if you have a computer built for gaming (with a good graphics card).
If you're looking for a computer that'll run Zwift well, we recommend picking up an Alienware. The Alienware Alpha packs an impressive punch for a modest price tag. The Alienware 15 laptops are also great if you'd rather be portable (and will run Zwift on the highest settings).
The technical answer:
Zwift runs primarily off your computer's graphics card. While it's important that your CPU is equivalent or better than a Core 2 Duo and has enough RAM, it's the GPU that's the most important.
You can compare your CPU against our recommended specs using a site like http://cpuboss.com/compare-cpus and your GPU using one of these resources:
- http://www.futuremark.com/hardware/gpu: Hierarchy chart of GPUs.
- http://gpuboss.com/compare-gpus: Tool for comparing your GPU against one of our example recommended models.
- http://www.notebookcheck.net/: You can search for your specific GPU model and see where it ranks in the hierarchy chart.
Bottom line: sometimes, it's just too old.
Even if your GPU hardware meets our minimum requirements, it can occasionally still be just too old to run the game. Zwift requires OpenGL 3.1 and some drivers for older cards just haven't been updated. So while your hardware may be up-to-spec, you may still need to either get a new card or a new computer.
