I've played GTAIV on PS3 for years. Just went and bought a copy on PC, my computer is fast enough to run it no-problem. Frame rate is almost better than the PS3. I would like help from some sort of modding guru who knows a sure fire way to get it running with the launcher mod installer etc. Have already tried but found nothing but conflicting information on how to do it, as a result the install and getting it to work was a huge failure. Have since removed everything and want to start again. Any help would be cool.
