The screensaver is really nice. But why does he on my PC spend so much CPU time? I think that screensavercan cann take more than 80% of CPU time and only 20% left for computing. Is it possible ??? |

That is the trade off between running the BOINC project screen saver, or switching to the the 'blank' screen saver. Any sceen saver is going to take time away from the actual project calculations; and this time can be very significant. This is way a lot of serious BOINC crunchers will switch the screen saver to the 'blank' one. There are those people who run BOINC for the graphics, in which case they accept reduced work unit availability.  You like Myst? Uru Live returns! www.urulive.com |

The screensaver is really nice. You need a decently-good (no need for very high-end) graphics card. If your graphics card doesn't have the 3D acceleration needed, all the 3D stuff will be emulated by your CPU instead. Even with a good gfx card, the screensaver will *always* use *some* extra CPU, so computation will be slower than without the screensaver. |
