The d3d9.dll tricked the game engine into thinking the DX 8 GPU was a DX 9 GPU and allowed the game to run. At the time a lot of people only had DirectX 8 GPUs. Oblivion was the first DirectX 9 game to be released. Http /The d3d9.dll file was originally created for the 'Oldblivion' project. It can be obtained from the following link. You need a d3d9.dll file that basically tricks the game into thinking the Intel HD graphics core is a dedicated GPU and will allow you to play the game.
However.įallout 3 and Oblivion (both use the same Gamebryo game engine) can be played using Intel HD graphics, but the game engine does not recognize integrated graphics (at least for Intel) to be valid graphic cores without a workaround. I never had a compatibility problem running Fallout 3 with those OSes. From a purely technical point of view, I'd assume most IGP from Intel COULD run it, but it's pretty much a dead game at this point.įallout 3 can be played on Win 7 and Win 8.1. Well, again, I don't think that Fallout 3 will run on anything else than XP or Vista.
