This will allow the driver to determine if and how to use threaded optimization for various games. It is recommended that Threaded Optimization be set to Auto under Global Settings. User feedback indicates that some older games, as well as some OpenGL games, will exhibit problems if Threaded Optimization is set to On. It should be noted however that none of the games I tested were old enough to have been developed before multi-core CPUs became available to consumers (around 2005). In testing this setting in several games, I saw no performance impact. Auto allows the GeForce driver to determine if it applies threaded optimization, On forcibly enables it, and Off disables it. The available settings are Auto, On and Off. In theory, by allowing the driver to offload certain GPU-related processing tasks as separate thread(s) on available CPU cores, performance can be improved. Threaded Optimization: This setting controls the use of multithreaded optimization for games on systems with multi-core/HyperThreaded CPUs. Nvidia GeForce Tweak Guide Nvidia Control Panel (Pt.4)
