Witcher 2 using wrong gpu
15.02.2013 @ 12:42 #1
recently it came to my attention that witcher 2 im playing atm is not using my nvidia geforce 540m card, instead its using integrated intel card. (checked it using nvidia gpu activity)
I have changed settings in nvidia control panel multiple times with no result, i "run the game with graphics processor", i even tried disabling integrated gpu through device manager (couldn't do it any other way) with no result as it turns out that one card needs the other to work.
My laptop asus n73sv has
Windows 7 home premium 64 bit
nvidia geforce 540m (drivers up to 310.70)
could anyone pls help me

This has been effective ever since nVidia's driver version 270. If it does not cause your system to use the nVidia card, then there is something incorrect in the way you have set it up.
And you are right in observing that you cannot disable the integrated GPU. In this architecture, it acts as a pass-through for the output from the nVidia GPU, so it can't just be turned off.

Regarding the drivers, i had originally, i think, 270.something, then i upgraded it to 310.70 and then to 310.90.
Now im trying to experiment with the settings in the "screen resolution". however on my screen nr 1, mobile pc display, when im changing it to vga it runs only if i had another screeen, which i dont, resulting in blank screeen.
I know that windows its not using my nvidia card for this option as now my resolution is 1600x900, and when i set up vga on my "other screen", i had an option to go as high as 1920x1200
I think it may be possible to set up vga display on screen nr 1, however i had no success on that part. If somebody could suggest how to set it up (or if its possible) i could either succeed in forcing withcer to use it, or at least rule out that option without goig back and forth like a madman
Should i post screenshots of my setup? maybe there is really sth i set up wrong, though i doubt it
