FO3 was Betheda's and simply incompatible with anything Intel claims is video. FO: NV was Obsidian, and what you're getting in that game with your video isn't what I consider "running", really. Bethesda does not offer official tech support for Laptops / Notebooks because most of them have Intel's bad excuses for video. While there may very well be some smoke and mirrors tricks that make that sow's ear seem to you to have become a silk purse, I don't feel it's my duty to promote a lesser quality experience than what Bethesda designed their game to act like and look like.
The very same holds true for any and all games that REAL video cards are the intended hardware for, including Skyrim and Oblivion.
I will amend that about Oblivion, I think, because their official system requirements were such total lies, no one could have known what PC they could have used.
Oblivion is the very least well optimized of their last four games, but because of Morrowind, had a readymade Mod Community already familiar with the tools. After the Modding Community took hold, the result was a greatly improved game, far better than the slipshod mess Bethesda had turned loose, and then never fully patched up.
One Modder in particular, Ball-of-fire, collected and tested hundreds of mods, and had a web site with several pages of collected lists there. The one that is of primary concern turns Oblivion into a much lower impact product that Low End hardware the same class and speed as Intel's chips finally managed to reach is able to run the game in spite of low performance capabilities. For more, see the comments about CTD behavior in Oblivion, in your thread at that forum.
