In 2017.2.0a1 everything works fine, but after upgrading this project to 2017.2.0b1-b3 the distance of projectile flight become smaller.
(The same happens in Standalones)

Not sure if this is A$ Project's problem or Editor's ...

How we can reproduce it
--- please see attached video ---
1 Create new project
2 Go to AssetStore and find "Tanks!!! Reference Project" (https://www.assetstore.unity3d.com/en/#!/content/80165)
3 Import this package to your project
4 Open Assets->Scenes->Menu->LobbyScene scene and press Play in Editor
5 Then in game press Training->Start->Start and do Left Mouse Click to shoot

Actual result: the distance of projectile flight is smaller in 2017.2.0b1-b3 than it was in 2017.2.0a1

Expected result: the distance should be the same in all Unity versions
