For people playing the Serious Sam games in VR, I'd like to recommend this mod: https://steamcommunity.com/sharedfiles/filedetails/?id=955691720
By default, the VR games allow you to spam the trigger and rapid-fire any weapon, which is bullshit. This mod fixes that, by enforcing the normal rate-of-fire for each gun. 
You do have to manually launch SS Fusion with Mod Support, and sacrifice any chance of unlocking achievements, but I feel like this is an essential improvement to the game in VR.
