Dolphin Viewer 3 has had a number of quick releases recently. Most of these are for fixing bugs. Recently there was a problem with shadows. That has been fixed in this release.
The announcement for this release is: Bugfix Release – Dolphin Viewer 3 126.96.36.19907.
You can find the downloads here: Dolphin Viewer Download.
The download is about 28mb and takes a couple of minutes.
The install is typical, nothing special.
The install saves all your settings. With Lighting & Shadows and Ambient Occlusion turned on with HIGH settings I get 20 to 25 FPS. Turning on Sun/Moon Shadows pulls me down to 16 to 18 FPS.
The shadows look pretty good.
One of the things I’m finding I enjoy is the feature in Preferences -> Dolphin 3 -> User Interface -> Allow Separate Search Terms on each Inventory Tab. Try it. You’ll like it.
