a quanto pare non è del tutto così, ho fatto una verifica e ho notato che il clock del motore grafico si modifica in base a necessità, per esempio se si usa in modo intenso la scheda video allora da 300 passa a 500mhz, mentre la frequenza ram a me resta invariata.
consiglio di aggiornare i driver all'ultima versione se li avete installati dal file nvidia.run, ho notato che sul sito nvidia non vi mostrano gli ultimi driver nella solita schemata, ma in una parallela un po nascosta, gli ultimi sono: NVIDIA-Linux-x86-171.05-pkg1.run
e sono quà
http://www.nvidia.it/object/linux_displ ... ve_it.html
vi comunico poi che ho scoperto una bella notizia per chi ha installato i driver nevidia.run, è indicata nella super guida
procedura molto semplice e veloce riguardo l'aggiornamento, è indicata nella parte finale della guida.

mi resta cmq sia un problema, in pratica certe caratteristiche attivate da nvidia settings non me le tiene, tipo anialiasing ecc, al riavvio me le resetta.
dovrò vedermi bene il percè, secondo me è solo un fatto di impostazioni parecchio nascoste da eseguire su terminale.
ora scrivo sotto la parte dell'aiuto di nvidia settings in inglese così uso google per tradurlo e capirci qualcosa
Antialiasing Help
Antialiasing Settings
Antialiasing is a technique used in OpenGL to smooth the edges of objects in a scene to reduce the jagged 'stairstep' effect that sometimes appears along the edges of 3D objects. This is accomplished by rendering an image larger than normal (with multiple 'samples' per pixel), and then using a filter to average multiple samples into a single pixel.
Several antialiasing methods are available which you may select between with the Antialiasing slider. Note that increasing the number of samples used during Antialiased rendering may decrease performance.
You can also configure Antialiasing using the __GL_FSAA_MODE environment varible (see the README for details). The __GL_FSAA_MODE environment variable overrides the value in nvidia-settings.
Application Antialiasing Settings
Enable the Antialiasing "Override Application Setting" checkbox to make the antialiasing slider active and override any appliation antialiasing setting with the value of the slider.
Off
Disables antialiasing in OpenGL applications. Select this option if you require maximum performance in your applications.
2x Bilinear
This enables antialiasing using the 2x Bilinear mode. This mode offers improved image quality and high performance in OpenGL applications.
2x Quincunx
This enables the patented Quincunx Antialiasing technique available in the GeForce GPU family. Quincunx Antialiasing offers the quality of the slower, 4x antialiasing mode, but at nearly the performance of the faster, 2x mode.
4x Bilinear
This enables antialiasing using the 4x Bilinearmode. This mode offers higher image quality at the expense of some performance in OpenGL applications.
4x, 9-tap Gaussian
This enables antialiasing using the 4x, 9-tap (Gaussian) mode. This mode offers higher image quality but at the expense of some performance in OpenGL applications.
8x
This enables antialiasing using the 8x mode. This mode offers better image quality than the 4x mode.
8xS
This enables antialiasing using the 8xS mode. This mode offers better image quality than the 4x mode; 8xS is only available on Geforce (non-Quadro) FX or better GPUs.
16x
This enables antialiasing using the 16x mode. This mode offers better image quality than the 8x mode.
Anisotropic Filtering
Anisotropic filtering is a technique used to improve the quality of textures applied to the surfaces of 3D objects when drawn at a sharp angle. Use the Anisotropic filtering slider to set the degree of anisotropic filtering for improved image quality. Enabling this option improves image quality at the expense of some performance.
You can also configure Anisotropic filtering using the __GL_LOG_MAX_ANISO environment varible (see the README for details). The __GL_LOG_MAX_ANISO environment variable overrides the value in nvidia-settings.
Override Application Setting
Enable the Anisotropic Filtering "Override Application Setting" checkbox to make the anisotropic filtering slider active and override any appliation anisotropic filtering setting with the value of the slider.
The Anisotropic Filtering slider controls the level of automatic anisotropic texture filtering.
Texture Sharpening
To improve image quality, select this option to sharpen textures when running OpenGL applications with antialiasing enabled.
