System clock res not stable

Hi, i have a weird situation.

When i spawn a Windows7-SP1 virtual machine, if i connect via RDP and i run Clockres (from Sysinternals), i obtain those value; ClockRes v2.0 - View the system clock resolution Copyright (C) 2009 Mark Russinovich SysInternals - www.sysinternals.com

Maximum timer interval: 15.600 ms

Minimum timer interval: 0.500 ms

Current timer interval: 1.000 ms

However, if i close the session, and i'm connecting via VNC from Horizon Dashboard, i obtain those value ClockRes v2.0 - View the system clock resolution Copyright (C) 2009 Mark Russinovich SysInternals - www.sysinternals.com

Maximum timer interval: 15.625 ms

Minimum timer interval: 0.500 ms

Current timer interval: 15.625 ms

Probleme: When a user execute some automatic script, the VNc current value (15.625) is used, so their script take really longer that they should be. When they connect via RDP, everything works correctly.

I think VNC is changing the Current timer interval, but i wonder why and how? Also, can we edit those value into VNC directly?

Do you think is possible to edit those value for VNC (I know we can't edit RDP, but it's okay) ?

Thank you for the support and your help :)
