Hey ya'll, just finished assembling my own copy of the New Vegas STEP modlist, and ran into two curious problems:
1) I also get the bRestore2Hotkey CTD from the IStewieAI ini file. As with others, setting it to = 0 fixed it. (I know you're already aware of it; just adding another data point, so to speak)
2) My HUD got kinda messed up, where Subtitles were non-existent and my cross-hair was just a small, overlay-coloured square in the middle of the screen, with some other smaller squares off to the left side. I was, however, able to fix this problem myself by re-installing oHUD without the DarnUI TTW Patch and the xml file change. Then it works just fine.
I am fully willing to concede I did something wrong, but I'm (mostly) sure I didn't, especially where I went back and re-installed a copy of oHUD with the Patch and the xml file edits to capture these attached screenshots, and re-produce the glitch.
Other than that, absolutely no complaints whatsoever. This is the smoothest I think I've ever seen New Vegas run, in fact!
