Well, if you could provide me the specific requirements to the game, I can analyze it more deeply. What overclocking is, is pushing the hardware beyond it's preset limit, so if you have a warranty, this would void it on that specific device. This could help performance a little, but on such a dated card, I don't know. Certain cards like that may not even overclock if they have been locked, or if there is a lack of utilities for it. As for mods, there are certain mods for certain games, (usually only the popular ones), that make it run on older hardware. For example, my friend saw oblivion on my Xbox 360, and wanted to play it on his PC, well, it wasn't that new of a PC. Oblivion uses cutting edge graphics technology, and requires a graphics card with Pixel Shader 3.0, so I found a mod called "Oldblivion", which enabled it to run on his PS 1.1 card. I don't know if there are similar mods for this game, you'll have to check.
