Run cpu_info.exe to determine which file to use. Place d3dx9_38.dll in your game's root directory. Additionally placing d3dx9_38.tmp there will bring up a console (black Windows terminal) which serves to verify that F3HR is loaded. INSTALL MANUALLY.

Simply place "d3dx9_38.dll" in your main game folder next to "Fallout3.exe". Delete "d3dx9_38.tmp" to disable the console from appearing. This was compiled with the AVX2 instruction set, it should be faster than the SSE2 version but requires CPU support.
