Why Slipstream?

Second Life has grown up a lot over the years. The way viewers draw it mostly hasn't. Slipstream is our answer to that.

The problem

If you've ever walked into a packed club or a big event and watched your frame rate fall apart, you've seen it. It happens even on expensive gaming PCs. The graphics card is sitting mostly idle while the rest of the computer struggles to keep up with everything on screen.

What we did about it

We rebuilt the part of the viewer that draws the world, using a modern graphics engine that hands the work to your graphics card. Busy scenes stay smooth, and it frees up room for nicer lighting, better shadows and features that weren't practical before.

In our own side-by-side test in a busy scene with comparable settings, Alchemy (the viewer Slipstream grew out of) ran at about 24 frames per second, and Slipstream ran at about 90 on the same PC. Every scene and every computer is different, but that's the kind of difference we're aiming for.

What it's like to use

It's still Second Life, with the same world, friends and inventory. Your existing account works as-is. Slipstream chooses graphics settings to suit your computer the first time you run it, looks sharp on high-resolution screens, and runs on both Windows and Linux. We've also added the kind of conveniences people ask for, such as a frame rate limiter, a third-person shooter camera and more flexible controls, and we keep adding more.

Where it's at

Slipstream is in beta. It's usable day to day, but you'll find rough edges, and bug reports really do help. You can file them on our issue tracker, and the help pages cover installing and common problems.
