Yeah those are things that I thought about. The load on my HDDs is not the issue because after the game has loaded it rarely reads from the HDD anymore. For example, when hosting a LAN game my PC naturally has to load first and then the client PCs load after words. My HDD activity light seems to agree as well. However the CPU load could be the culprit. Perhaps 7 has a higher priority for games then it does for file sharing. Does anyone know how to change that? I might try giving the game a low priority and see if that effects it but I would rather only have to change the file sharing priority...
