Oke so when I use oxide enb the game crashes at the start, I followed all the instructions. Though when I use something like blackout enb the game works fine. Yes i have the leatest d3d9.dll...

Firstly, make sure that you have cleared all ENB files out of your game folder (SteamApps\common\Fallout New Vegas)

Find the ENB D3D9.dll file within the enbseries_falloutnv_v0267.rar and put it in your game folder (link directly above)

Now grab all the files from the Oxide ENB archive (except for the Data folder) and place them in your game folder as well.

Then install the files from the data folder (of the archive of this ENB) to your game (manual or via a mod manager, I suggest M.O.)

Next make sure you TURN OFF anti-aliasing and anisotropic filtering in the games launcher.

If it is still crashing make sure that you have FNV4GB Installed and if that doesn't stop it then maybe your computer is not capable of running it. If you think that is the case you can send me the specs and I'll see if this is the case

A thought just came in my head. Have you cleaned your game with FNVedit? It may not be the reason but it is still a good tool to have. Also if you haven't download LOOT as the game could be crashing due to your load order perhaps?

*Sigh*

Try seeing if any of the tips at the ENB Troubleshooting thread solve your problem.
