I've just migrated my old PC to Windows 7-Pro-SP1, and now: 3DMark2001SE score is 12000pts.
I had 17000pts when running WinXP-Pro-SP3.
Of course, I ran before migration, the "Microsoft Windows 7 migration advisor" and it just told me all will be fine.
All the windows update did run OK.
I've tried to replace the video-driver
with the last nVidia, score is lower: 11000pts.
Of course, no anti-virus during the test; and task-manager is calm.
So I think I encounter a problem, but where to search ??
P4 3.2GHz HT
2500MB DDR1 in dual-channel
video AGP 8x 7600GT
HDD 500GB SATA1
all hardware exactly the same as under WinXP
Thanks in advance,
