Windows 7 GM5 Ploytec Driver

[Breeze]

I ran MIDItest on W7-64 with my GM5 interface using the 1.0.10.0 Plyotec drivers on my Q6600 system and got these results:

Byte latency:       0.82 ms

Byte jitter:        0.32 ms

Byte max deviation: 1.82 ms

Then I found these better results on this post using the GM5 on Vista-32 and using the 1.0.6.0 Ploytec drivers on a similar Q6600 system:

Byte latency:       0.16 ms

Byte jitter:        0.16 ms

Byte max deviation: 1.02 ms

That's quite a discrepancy. Could the drivers be responsible for this?
