Nvidia card no more connected and zooming very low

[BikeSurfer]

Hello,

I have a graphic performance problem.

Zooming is so slow it is unusable (for example with google maps).

I checked the Nvidia pannel, and it says that there is nothing connected to a Nvidia processor !

The other checks sho that the card is Intel and not Nvidia despite the fact that the HP diagnostics says that there are two graphic devices the first one being Intel Graphics 630 and the second one being NVIDIA GeForce GTX 9520M.

The fact that the zooming is very slow and that the card seems not used by the system make me think that the card is somehow disconected, but I don't see anything to do in oreder to connect it...

thanks for any advice

I have found some answers :

1) install the last official Nvidia driver : I have now access to the Nvidia pannel

2) change the windows energy options to max perf

3) Last but not least, within system option ther is a graphic option at the bottom. Tha allows to choose max perf with Nvidia card or intel for slow (min energy I suppose...) for each executable.

After choosing the right options tha's way better with Opera, the gmaps sat. view zoom is really quick.

Firefox is very slow, I think it is not related to the PC.
