sims 3 64 bit update

@BrownNy13  I don't use a compatibility mode; the game has always run fine for me in Windows 10.  Other than using an fps limiter and getting my card recognized, I haven't had to do anything else.  One step that may help, or at least it helps some people, is disabling Game Mode and Game Bar in Windows settings (Windows key-i > Gaming).  If the game runs worse though, it's easy to undo the change.

I do often get a slight stutter when moving the camera, but it doesn't bother me.  It's less that fps drops than that the camera isn't completely smooth.  This is typical with newer graphics cards, although not all of them are affected.  If the stutter is infrequent or unobtrusive, it might not be worth pursuing.

If you want to try to fix it and it still only happens when fps goes above 60, then try using the Max Frame Rate setting to cap fps at 60 or 59, as described earlier.  Please also try playing in both fullscreen and windowed modes, to see whether either one is better.  If windowed mode runs better but you don't like the size of the window, there's a utility called Windowed Borderless Gaming that give the fullscreen size with the functionality of windowed mode.  But test it first to see whether windowed mode even makes a difference.

It's also possible that, if you applied some of the graphicsrules.sgr edits mentioned in the Steam guide, those edits are having a negative effect.  I don't actually know how they'd affect your graphics card, but it's also worth testing without those edits.  If you don't want to go through the whole process again, you can copy both .sgr files to your desktop and then repair the game in Origin, which will undo the changes you made, then copy over just the edits that get your graphics card recognized.  If you don't notice a difference, you can delete the .sgr files in Program Files and move over the ones from your desktop.
