guarda cosa ho trovato sulle faq: se ho capito bene dice che rivatuner si può chiudere e nel caso in cui non sia stato usato per l'overclock si può anche disinstallare
Q: Can I close RivaTuner after changing the driver's settings? Will the tweaks have an effect in this case?
A: Yes, of course. All the driver's settings are stored in the registry so you can safely close RivaTuner or even remove it from your hard drive, but the tweaks will still work. It's not necessary to load RivaTuner at Windows startup in order to apply the changes you have made. The only options which require RivaTuner to reside in memory are the 'Restore clock frequencies after suspended mode' and low level refresh overrider module. The power users may also wish to keep RivaTuner resident in order to use built-in registry editor's and low level diagnostic module's tracking features.
Q: And what about the low level overclocking? Will it work if RivaTuner is not loaded at Windows startup?
A: Yes, it will. The only condition is not to remove RivaTuner's folder from your hard drive. RivaTuner adds itself with the /S command line switch to the autorun registry key when you enable any low level settings (e.g. overclocking or color correction) at Windows startup. When this command line switch is specified, RivaTuner loads itself at Windows startup, executes startup daemon (the procedure that configures startup settings depending on the settings you've made) and unloads itself from memory immediately.
