3D Marine Screensaver shows underwater life with a couple of fishes, a crab, bubbles, a clock, and even frames per second (FPS).
Itâ€™s a few years old now at the time this is posted, and the original website it came from is gone, so there wonâ€™t be any support. Thereâ€™s not a real lot going on here. You get the same scene over and over lasting about 30 seconds, but then again, I personally rarely sit and stare at my screen for no reason. Then again, some screen savers are more entertaining or interactive. Tough call here, but it is entirely free.
There are a lot of options for a screensaver of this age. By default, it will try to use your desktop settings, but you can adjust the gamma, so it is brighter or darker. You can see a clock in 2 different formats, show FPS and opt to exit on mouse movement. By default hitting any key or mouse click will exit. Volume control is included, and the sound is just a piano.
3D Marine Screensaver seems to use a fair amount of CPU and memory by today's standards, but then again, youâ€™re not doing anything when it runs. Overall itâ€™s the best feature that itâ€™s free and not loaded with any additional software, and it's more of a retro screensaver than anything else.
