Z buffer rendering seems to have broken for me with Kingdom Come Deliverance 1. Not sure if this broke with an update, as it was working. Z Normal and Z Adaptive both look flat – the same as 3d off. G3D still works though. I have reset vorpx to factory default. I was using Nvidia 572 drivers and upgraded to 581 but no change. I’m running vorpx 25.1.2
Can’t replicate. Do not diable vorpX’s automatic setting feature and reset the game’s graphics settings to default. Sometimes 3D modes working depend on one or the other game settings being set to a certain value.
Thanks Ralf. Tried resetting the game graphics to default – no change. Even deleted the profile and shader folders in users/<user>/Saved Games/kingdomcome to force them to be recreated – no change. Verified game files with steam but still have the issue. There’s a flicker when I switch between 3d off and z-adaptive but both z-buffer modes still look flat with no 3d (3d strength is set to 2.00). Z-Buffer modes are working fine with Fallout 3. Short of reinstalling both game and vorpx not sure what else to try
Update
Tried resetting game graphics and vorpx settings to defaults again and z-buffer modes started working. However, they only work at 1280×720 windowed, which is the resolution the game defaults to when settings are reset. Changing from this resolution seems to be breaking z-buffer modes for me. Vorpx will change to a different resolution and on restarting the game the z-buffer modes are no longer in 3d. Turning off vorpx resolution changing and changing the game resolution back to 1280×720 then restarting the game reenables the z-buffer 3d reconstruction.
I have exactly the same problem with Horizon Zero Dawn Forbbiden West with Death Stranding profile. Z-normal was working perfectly before the recent updates.
