Are you sure that you are comparing workunits with the same name? | |

their are certain background effects in windows 7 that eat up just a little bit of the resources of the card... | |

the visual effects in windows has the option to be put on custom, performance, and quality, it's most likely set to quality. try performance to see if the time steps go up. | |

oh, Ive found it, well lets see what it changes.. | |

Actually nothing changed, completed another GIANNI-BIND WU and still 47ms/step :| | |

I just did that and i compared two GIANNI-BIND(?) WUs on Xp i had 35ms/step and on win7 46ms/step :| Because of your post I checked my results and see something similar happening. On my GTX 260 the GIANNI-BIND WUs went from 42ms/step to 46ms/step when I switched from XP-64 to W7-64, compute time went up from 27k to 30k per WU. My Win 7 has Aero turned off, 4GB ram, set to performance instead of appearance. All other projects that I've checked (except this one) show comparable performance in XP-64 and W7-64. Collatz, MilkyWay, NFS, Virtual Prairie, PrimeGrid 321 Sieve, Docking, and Leiden are the ones I've checked and they all show no slowdown. Wonder what's going on? | |

zpm, i tested my old Xp boinc 6.5.0 and this now 29.10.2009 04:17:30 Starting BOINC client version 6.6.38 for windows_x86_64 | |

zpm, i tested my old Xp boinc 6.5.0 and this now 29.10.2009 04:17:30 Starting BOINC client version 6.6.38 for windows_x86_64 Here's your XP-32 machine with a GTX 285: # Time per step: 44.423 ms # Approximate elapsed time for entire WU: 28874.760 s http://www.gpugrid.net/result.php?resultid=1393869 Here's your Win7-64 machine with a GTX 285: # Time per step: 46.260 ms # Approximate elapsed time for entire WU: 30068.907 s http://www.gpugrid.net/result.php?resultid=1441435 Looks like the XP-32 machine was probably using an older driver too (not specified for some reason). Not as big a difference as we're seeing though... Edit: Your Win7 machine also used 2.5 times the CPU time. | |

I just did that and i compared two GIANNI-BIND(?) WUs on Xp i had 35ms/step and on win7 46ms/step :| Edit: The CPU usage is also consistently double in Win 7 compared to what it was in XP for the same type WUs. | |

so all in all W7 seems to be bad for boinc? :< | |

so all in all W7 seems to be bad for boinc? :< As stated above, GPUGRID is the only project of the ones I've checked (Collatz, MilkyWay, NFS, Virtual Prairie, PrimeGrid 321 Sieve, Docking, and Leiden) that shows this slowdown in Win 7. What we'd like to find out is why and how it can be corrected. | |

So lets hope some GPUGRID Staff member see's this and forwards this problem of W7! | |

So lets hope some GPUGRID Staff member see's this and forwards this problem of W7! If this slowdown only happens in GPUGRID maybe it's not a Win 7 problem, but a project app programming or compiling problem? | |

Well I dont know, all I can say if there wont be any solution all I can do is switch to another project then =) | |

Now all of a sudden my GTX285 starts giving out Computing errors... if you're switching projects, collatz is a good option as seti is out of work and are trying to bring some more work up. | |

ah ok thank you for that info, after rebooting my system it seems to work normally again lol | |

Most likely the drivers aren't as mature. | |

Don't think it's a problem with the driver because performance in other applications (games, benchmarks etc.) isn't worse... | |

I think it may be a driver problem. I was also experiencing a string of errors with upgrade to win7-64bit on my GTX260, sometimes had to reboot, Wu taking too long and not using full ability of card, etc. With the 195.62 WHQL release this seems to have rectified itself, thankfully. :) | |
