Extremely Low FPS in Live Mode

@masunka77  Just to set a baseline for performance, please start a new save, load into one of the base game starter homes in Willow Creek, and let me know what kind of framerates you see.  The point here is not to say your current save or lot is broken, only to narrow things down.

Please also run a dxdiag and attach it to a post, for reference.

Sorry for the late reply. The FPS in one of the base game homes is 35-60 (for a second it was 27, but it never got this low after). 

@puzzlezaddictI think it’s also worth mentioning that on some bigger EA lots (64*64 Villareal Mansion in Windenburg) GPU, RAM and CPU are slightly more loaded but the FPS is more stable and higher in general (35-60). I’ve never seen it be higher than 60 though. My NVidia limit is 120. I play offline with no background apps. And a day ago when it was snowing in my game the snowflake texture was missing. It was snowing transparent squares with an interrogation mark on them, so I downloaded a custom replacement. The raindrop texture is fine. I’ve been having the FPS issue even before I noticed the snowflake issue, but they might be related.

@masunka77  The missing textures/question marks is a symptom of an incomplete install or a problem with custom content.  Instead of using the replacement for snowflakes, please try repairing your game: open the EA App game library, click Sims 4, and select Manage > Repair.  Then test without the replacement, and without any other cc present.  You don't need to save your progress.

I would expect your game to run above 60 fps at least some of the time, even on ultra graphics settings, and the fact that lowering the settings doesn't help much just underlines that there's something else going on here.  By playing offline, do you mean you put the App in offline mode, or do you disconnect your computer from the internet entirely?  If you haven't tried the latter, please do so, just as an experiment.

Additionally, have you changed any settings in the Nvidia Control Panel other than the Max Frame Rate?  If you've enabled vertical sync as well, either for Sims 4 or overall, please disable it.  Or just reset the Control Panel settings to default and see how it goes.  If you've enabled vertical sync in the game options, disable it there too.

Please test in both fullscreen and windowed modes and let me know whether one is better than the other.  And play with ultra graphics, or as close to it as you would normally, rather than low.

If that doesn't help, please try playing in a clean boot:

The one service to leave enabled is the EABackgroundService, which the EA App needs in order to run.  Disable the rest as described.

When you reboot your computer, go through the Task Manager's background processes list shutting down any service that doesn't absolutely need to be running, for example anything from MSI Afterburner to RGB software might still be enabled.  If you accidentally kill a critical process and it doesn't restart on its own, just reboot your computer again.

Don't open anything other than Sims 4 and the EA App while testing, not even a browser window, and stay offline.  This is obviously not a great way to play Sims 4 in general, but it's a helpful diagnostic.

@puzzlezaddictI play the game with no Internet connection. In NVidia Control Panel, I didn’t alter the VSync setting, but Antisotropic Filtration is 16x and some Transparency setting (I don’t remember its name) is x8. Also ensbled triple buffering, some other options as well and made the game use my NVidia GPU long ago. I disabled VSync in the game settings but it didn’t do any better performance-wise, only brought distortion while the camera’s moving.

@masunka77  I'd reset the CP settings anyway, just in case they're somehow contributing.  And let me know whether windowed mode is better than fullscreen.
