In many games I feel as I am a Giant. Overload, Sublevel Zero, Everspace, it's always the same. The Cockpit Looks very big with a big seat. In Project CARS 2 too but there is an Option to set the ipd Ingame. Is this normal or an issue, I think all games are optimize for VIVE.
FOV and IPD are two very different things. FOV is measured in degrees and determines how much you see in front of you in an arc. IPD is the distance between your pupils measured in centimetres. Having the wrong IPD for your headset (changed by the slider on the right under the HMD) means that you'll have problems focusing on things close to you in VR and will have your eyes straining to see things in the distance.
The scale of things in games is what you're talking about and is purely down to the developers in question and shouldn't be affected by changing any settings. The scale of any models in a VR game will appear the same size in both headsets.
