Tak jsem dostal odpověď od Matroxu viz.

Unfortunatly there are no release notes available on the site for the 5.88 drivers.
In General, new drivers contain fixes for issues that have been reported and fixed.
The only info available to tech support on the released drivers is what is in the release notes.
If you are not having problems with the drivers you are currently running then there is no point in upgrading.
Dobrý co ?
