Game unable to detect Nvidia card - possible fixes?
Setting the game to use the NVidia card is all about the NVidia control panel, the game uses the graphics card that its told to. The age of the card is not the problem, the NVidia GT 820M has been in use with the Sims 2 with other users (same graphic card family).
So the question is more about what you're doing in the NVidia panel.
You are completely correct about the INTEL card - and if we can't get the NVidia working, we can fine tune that to give best-case resolution and working. Which will be an improvement on your current configuration.
To be honest, the INTEL tweaked and the NVidia are not that big a difference.
You need to tweak both the Graphic rules and the Video cards.sgr for optimum performance.
