so i had a enb installed for a long time but suddenly one day when i launched the game it was just pure black but the game ran i could hear the game menu click sounds.

so i narrowed* it down to the HDR setting in fallout new vegas if i got i set to bloom/off it works but the enb glitched out if i dont got hdr on
anyone ever experience it

PS tried several enbs and versions and i also tried enbs in fallout 3 but it works in that game

I can't say I understand what's going with your game, but there're only two things I can think of that would make your screen go black:

1. The ENB comes with a Colour-Palette and you have it accidentally deactivated. Check in the enbseries.ini for "UsePaletteTexture=true".

2. Something has messed with your Renderer-Settings. Make a backup of the Fallout-folder in the user/My Games folder. And then delete or rename both .ini-files and the RendererInfo.txt.

@"shadowshade" thanks il try it i played this game 4 years on pc and never experienced it before. thanks for response!

Sorry, I forgot to tell you that when you try what I wrote under point 2, you need to start the games launcher afterwards in order for the game to re-detect your hardware and re-generate some files. After that you can adjust the settings in the launcher for the enb and then start as usual via the nvse-loader.
