You will notice a perfromance drop dureing some more intensive quest mods, when this happens try disableing it using the F12 hotkey. This is due to the age of Fallout New Vegas, your high end system will not make a diffrence. Of course, it could be my fault, but having it be in the past being able to install it just fine, and retrying from scratch many times using ENBand ReShade manager, I think its something in the video. Important Note: While ENB’s do vastly improve the apperance of the game they will also cause performance issues. Sadly I'm nowhere near smart enough to have any idea where a problem could occur between this video and the ENB not working. I've installed the same exact ENB multiple of times with no issues except this time. I'm pretty sure this has to be due to something in the video. I followed all of the steps except for the ENBoost one because I wasn't sure if I could do it and also have an ENB installed. Ok, so I'm trying to get Rudy ENB to work after watching this video on stability for Fallout NV.
