The Rainbow Viewer : Designed for Older Hardware and Open Sim

By Avatar JayR Cela

    Now this viewer is pretty unique, especially when you consider that it is not based on SnowGlobe code, but the older 1.23.x LL - SL Viewer. There are quite a number of features you would expect from a more up to date code base. Better Alpha rendering, Restrained Love 2.7, a login manager for multiple grids, focusing mainly on Open Sim. A media filter, Animation Overrider,  ( AO ) Teleport History, and Quarl Lindens Alignment Tool, Display Names, Multiple Attachment's, Inventory Links, Radar and a slew of other small under the hood enhancements.

    Perhaps the best part could be that it is specifically designed to run on older or lesser hardware ( NetBooks come to mind here ) is available in SSE and SSE2 optimized version's as well. So I decided to give it a spin on a Athalon 64 1 Gig Ram ~w/Nvidia 7300GT graphics 512mb Ram.

    You will need some Non-Redistributable Libs from the official LL SL Viewer, so it may be a good idea to install that beforehand, or manually install them yourself.

Decent FPS of about 11, everything loaded quickly, including my inventory in the back ground.



    I was so impressed I decided to take it down a notch and try it out on a P4 1.6 with 512mb Ram on a 256mb Nvidia 6200GS and got similar result's.

    During my testing I was unable to locate a Grid Manager ( it does come with 40 pre-loaded Open Sim Grids already ) or the Animation Overrider however. I do not have a lot of time to devote to 1.x based viewers, so it could be I just missed something along the way.

    The Developer Boy Lane claims that Rainbow is actually capable of running on Pentium 2 class computers, he may well be right. Would defiantly be a good candidate for a Net Book.
