@peno11 As it turns out, the desktop 3050 isn't even in the database, only the laptop versions. (That may be because the file hasn't been updated in almost a year, according to its timestamp.) But you can add it easily enough. Open graphicsrules.sgr and ctrl-F to search for Nvidia, which will take you here:
vendor "NVIDIA" 0x10B4 0x12D2 0x10DE
card 0x1DBA "NVIDIA Quadro GV100" $cardLevelUber $resolutionHigh
card 0x249C "NVIDIA GeForce RTX 3080 Laptop GPU" $cardLevelUber $resolutionHigh
card 0x24DC "NVIDIA GeForce RTX 3080 Laptop GPU" $cardLevelUber $resolutionHigh
Under the Nvidia line, add this:
card 0x2507 "NVIDIA GeForce RTX 3050" $cardLevelUber $resolutionHigh
Make sure this entry lines up with the ones below; that means four spaces from the left.
You can save your own copy of graphicsrules and put it in ConfigOverride, inside Documents > Electronic Arts > The Sims 4, and that will override the file inside the game's program files. The copy in the program files will also be reverted to its original form with each update or repair, so putting a copy in ConfigOverride avoids the problem of having to edit the file over and over.
