heya,

my GTX285 is running slower on Windows 7 64bit!

on XP i had 30-40 ms per step and now i got 45-over50 ms per step!

what could be the reason of this?

just AERO ???

thanks in advance

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

I just did that and i compared two GIANNI-BIND(?) WUs on Xp i had 35ms/step and on win7 46ms/step :|

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

my computer, system properties, advance system settings, advance, performance, choose what you want to see and not see under visual effects.

this may help.

zpm, ty for ur reply, but I dont really get what u want me to change !? :D

could u explain it more detailed please?

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..

for now it looks like XP cuz i turned off everything :o

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

specify the differences between the 2 systems.

no difference its same system just before it was win XP SP3 32bit and now its W7 64 bit

in task manager, bump the priority up to high. idk, it could be a number of things,

client version, to many programs running, something could be slowing it,...

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

booth the same no difference.

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

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

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.

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? :<

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!

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 =)

had to do the same with my GTX260 was like the 1st here that started to error out all WUs when thoose 2.0(?) WUs came and it once had 18k RAC R.I.P :-D

well lets see what happends and if something will be done
