Linden Labs is desperate for the spread of new viewers in their Second life. However, the 2.0 viewers are disliked by many existing users. The viewer may be good for 2D, but it is the worst for a working screen of 3D. Because load depends on the PC very much, as for it, people giving up SL may increase.
Why did LL push this viewer to the users forcibly? Perhaps some users may be pleased with this. It is only the user who is interested in media connection to the last.
A large-scale connection handicap is generated today of the thing which made a new viewer. I seem to do LL elsewhere than the viewer. It is construction of the more stable metaverse.
