nvidia 4 420 Go drivers

[sndrsn]

I have a PCG-FR215H which has an nVidia 4 420 Go graphics card, to which I want to update the drivers. The nvidia website says I must get these from my manufacturer but that download is not mentioned in the support section. What should I do?

Nothing much you can do - Sony haven't issued any updates.

Hi there
i hade the same problem with my nvidia go 5600, the latest games crashed or din't work properly.
i downloaded the latest dirvers from nvidia and instaled them. this resulted in a directory "NVIDIA Display Driver" on my c drive, but did not install the new drivers.
i then went to the graphics card menu and forced a manual update, overriding all warnings and selected the above mentioned directory.
it wont find the proper dirver but showed list of all supported cards. in my case, i choose the 5600 (without go) , again overriding all warnings, and it worked perfectly. it is not faster but more compatible.
in your case i would try the mx 420 driver from the list.
Of corse there is no guranatee, it is at your own risk.
