Cinder Roxley announced the release of a new viewer version a couple of days ago. I just noticed. If I am reading right, this is the only main version update in a year. There have been beta updates. But, this one is an official main release, no beta.
See: Alchemy Release 5.0.6.41161. It comes in 32 & 64-bit versions for Windows, Mac 64-bit, and Linux 64-bit. Download links are on the announcement page. The release notes are here.
I find the viewer slower than the Linden and Firestorm viewers. In a crowd, I run about 15 to 20 FPS. In places where FS and LL run in the 80-90 FPS range Alchemy runs in the 50’s. In isolated places where LL & FS run 100-110 FPS Alchemy runs 130 or so.
Alchemy doesn’t support RLV, yet. Bummer.
I describe Alchemy as a nicer LL Viewer. Nice clean U.I.
