qubes-windows-tools degrades performance of hvm

[Cranix]

Hello,
I'm using latest qubes os with latest's dom0 updates.
I'm using version before the latest qubes-windows-tools.
I have setted up HVM with windows 7 ultimate 64bit version,
everything was fine.(i had to do a hack with changing graphics name
to cirrus, and next enable unsigned drivers).

After installing qubes-windows-tools HVM managed to start
but i am experiencing huge lag when trying to do anything on this HVM.
I mean to open start menu i need to wait 4 seconds.

I made a few attempts, excluding various components of
qubes-windows-tools but with no effect.

Everything else is working fine on my setup.
I have checked logs but i did not seen anything intresting.

Have You any ideas what can cause problems?

Check CPU utilization in Task Manager. IIRC the mouse simulation code is very cpu-heavy.
