I recently wiped my harddrive and put a fresh install of Windows 8.1 on my computer. Pretty much the only 3-D game I ever play on a computer is GTA III, so I went ahead and installed it. I also installed an HD mod after playing the game once to improve the car models and textures, but I can't get the textures to be re-optimized (I believe "optimize" is what the game says the first time you run it) to display the new textures correctly (I know it's not an issue with the mod itself because I've run this mod on multiple installs of GTA III on other computers without a problem). I know that the standard procedure for getting the textures to re-optimize is to delete txd.img and txd.dir from the models folder, but these files aren't there with this install. I've tried multiple ways to get the textures to re-optimize including (but not limited to) uninstalling the game from my computer and deleting the GTA user files kept in my Documents folder and then reinstalling and running the game with no mods installed, and I still can't get the textures to re-optimize. There must be something somewhere on my computer that the uninstaller is missing that's remembering the current "optimization" for my textures and not allowing me to re-optimize them. Can anyone guide on me on how to remove this information from my computer, whereever it may be, or how to manually force a re-optimization of the textures?
I've placed this question here rather than the PC Modding subforum because the problem persists even with no mods installed, so it doesn't appear to be an issue with the mod at all.
