So, after about 2 days of frenetic Googling and stuff, I'm finally making an account just to ask this:
My laptop has a NVIDIA Geforce GTX 960M. It is more than sufficient to run the game. I have the latest 388.71 NVIDIA drivers. I have both sims4 exes set to run using the NVIDIA GPU. My DxDiag output is:
https://pastebin.com/APG3xzRQWhen I mess around with the files, this is a section of the GraphicsCards.sgr file in the bin folder:
card 0x1618 "NVIDIA GeForce GTX 970M" $cardLevelUber $resolutionHigh
card 0x13D9 "NVIDIA GeForce GTX 965M" $cardLevelHigh $resolutionHigh
card 0x1619 "NVIDIA GeForce GTX 965M" $cardLevelHigh $resolutionHigh
card 0x1427 "NVIDIA GeForce GTX 965M" $cardLevelHigh $resolutionHigh
card 0x139A "NVIDIA GeForce GTX 950M" $cardLevelHigh $resolutionHigh
card 0x1347 "NVIDIA GeForce GTX 940M" $cardLevelMedium $resolutionHigh
It can be clearly seen that my card is missing from that list, even though cards inferior and superior to mine are present.
Can somebody send me a copy of their Sims 4 GraphicsCards and GraphicsRules files that have my card included? Or offer some other sage advice?
