nv的官方回应。
用google翻译的老外客服,呵呵。
Hello,
Thank you for contacting NVIDIA Customer Care
This is Srivathsa assisting you with the issue
I understand from your email that you that you are not able to get the video memory of the GPUs to be used completely by the games.
I see the screen shots provided in the web link and the page can be translated to English with the Chrome browser and thus no issues with the language.
I am sorry, I dont think there is any issue with this. It is an expected result with the video memory. The dedicated memory on the NVIDIA card is used only if the application rendering is higher than the screen refresh rate to next frame.
Video memory is used to store the frame that is rendered by the graphic chipset, but yet to provided to the screen. If the game is graphic intensive, the speed of processing to render the frame will reduce and thus no of frames in the buffer would be less.
Thus usage of the memory is game and the graphic card specific. A graphic card like GTX 670 may use more video memory than the GTX 660 Ti. Because for the same game GTX 670 or GTX 680 can generate more frames than the GTX 660 Ti
MSI after burner cannot change the settings of usage pertaining to the video memory.
Please update us the results at your convenience.
Best regards,
Srivathsa,
NVIDIA Customer Care.
nv的官方解释是,之所以在1536m附近打转的一个原因,是因为660ti的速度不够快,所以不需要那么多的显存来渲染。
