I searched and found several suggested fixes for this condition, but none of them fixed the problem. The roulette wheel would spin continuously. After that, I started having problems when loading a Save game. The game worked well for about a month after installing the DLCs. I have Fallout New Vegas installed with all the updates, including the DLCs downloaded from Steam. I've installed all the latest drivers and Windows updates. I have a Radeon HD-7750 video card with 1GB memory. Hi, I'm running Windows 8 64 bitt with 8 GB RAM.
