SlipstreamSecond Life,
without the slowdown.
Slipstream is a Second Life viewer rebuilt for the computers people actually have today. Clubs, events and crowded sims stay smooth, the world looks better, and built-in migration tools bring your settings and chat history over from Firestorm, Black Dragon or Alchemy in a few clicks.
Free and open source.
Built for busy places
Most viewers slow to a crawl when a sim gets crowded, no matter how good your graphics card is. Slipstream was rebuilt from the ground up so your graphics card does the heavy lifting, which is what it's good at.
Your results will depend on the scene and your computer.
What you get
A modern viewer, with the everyday things you'd expect.
Smooth when it's crowded
Events, clubs and shopping sims with lots of avatars stay playable.
Better lighting and shadows
Lights cast proper shadows, and newer graphics cards can use ray tracing for even cleaner results.
Set up for your computer
It picks sensible graphics settings for your PC on the first run, from laptops to gaming rigs.
Sharp on modern screens
Crisp text and a crisp world on high-resolution and 4K monitors.
Windows and Linux
First-class on both, including modern Linux desktops.
Handy extras
A frame rate limiter, a third-person shooter camera, flexible key bindings, instant jumping, and better building and scripting tools.
