Hi,
If you want to stick to official ASUS approved drivers, use just the ones posted on the
ASUS download site .
It looks like you may have a download link from the ASUS global site which may be fine (although it has version *3.0707 while my U.S. download site link does not?), but I usually try to stick to the usa.asus.com site for the U.S. region.
Our
ROG downloads can be used too and appears to be the same as the U.S. region downloads.
ASUS also has a 'secret'
download site for unapproved vga drivers used by newer or current ASUS notebook models.
You can go to the nVidia website to try to find drivers for your notebook nVIdia graphics card as well, but these haven't been approved on the ASUS side and may not always work that well.
If you aren't having any problems and don't have a reason, you may not want to update drivers just in case something goes wrong although I wouldn't expect this to happen often with the approved drivers.
The ASUS driver downloads site also includes the date they were posted (I see the 3.0614 driver was posted 10.20.12), so you can get an idea how long ago they were released.
Hope this helps!
