My experience is similar to ResetXPDR. Overall I’d like more brightness and contrast available form the G2.
When you describe the display as ‘overexposed’, is that the whole display (every direction), or are you talking about the effects added by the sim when looking from inside the cockpit to outside; or when looking towards the sunlight? This effect seems to have been added to simulate the effect of changing brightness on your eyes and can make the world appear very bright and washed out. Some people find this quite realistic, some hate it.
There are quite a few threads on this topic (most of them very rambling), but you can vote on a request to have more control available for the VR display here:
