Fix by haolink Megadimension Neptunia VIIR - VR Fix Explanation Megadimension Neptunia VIIR has some cool VR segments, The issue here is that the team who ported this game to the PC, Preapp Partners, have specifically hardcoded lens shapes only for CV1 Rift and HTC Vive What the game does is instead of obtaining the data from SteamVR is checking which vendor your headset is and thats all. You got a VIVE Pro or VIVE Cosmos? Means it will apply HTC lens distortion You got a Rift S or an Quest? Rift Distortion it is. You got another vendor then HTC or Oculus? Then the game simply closes SteamVR connection, which causes the game still to try and output the scene to a VR headset which causes it to crash since it has nowhere to output it to. What this patch does is trick the game into thinking your vendor is HTC, which allows you to play the VR segments on any VR headset (with some downsides, see Known Issues) Installation Download DeltaPatcher Extract the contents and open DeltaPatcher Set the Original file to the location where v2r.exe is located in (You can open the location by going into steam and right-clicking the game and then Manage > Browse Local Files) Put the .xdelta patch into XDelta patch. Optionally, you can also backup the original file by clicking on the cogwheel in the bottom right and selecting Backup Original File Press Apply patch Make sure to always launch SteamVR before opening the game, otherwise the game will crash on VR segments. Known Issues The game always runs at 920x1080 SteamVR scaling does not work The game stutters/twitches alot in VR, albeit in a playable state. Since the game applies the VIVE lens shape, the game may look distorted on other headsets, this is not an issue on Valve index due to how similar the lens shape is compared to VIVE. The game freezes if you click out the window or minimize it.
