Not really a bug, but...
With the end of win7 support, i'm thinking about upgrading my renderfarm from win7 to win10.
I've done so on one node for testing :
Upgrade, not fresh install : as those servers are oldies and scecifics, i don't dare a fresh install, i may not find drivezrs, so upgrading is safer.
As you can see, DR render seams faster on win7 than on win10... though win10 uses less ram...
Coincidence ?
did somebody made some tests ?
