Re: Weird Mouse Lag

@A_Fulcrum_Agent  That update is quite the plot twist.  I have a Razer (wired) mouse and use borderless almost exclusively, and I've never had this issue, although I've barely run the game since the last patch.  It would still be interesting to know whether your wired mouse has the same issue.

@A_Fulcrum_Agent  Alright, to be completely thorough, please do all of these together, even if you've tried all of them separately:

• Clear Origin's cache, then repair the game in Origin: open your game library, right-click on the Sims 4 icon, and select Repair
• Move your entire Sims 4 folder out of Documents\Electronic Arts and onto your desktop, and don't add anything to the new folder that spawns the next time you play
• If you have GeForce Experience set to optimize Sims 4 settings, please disable that option (before the next time you launch the game)
• Restart your computer
• Go through the Task Manager and end any background tasks that don't absolutely need to be running: RGB software, MSI Afterburner, Discord, whatever
• Don't open any apps at all other than Origin

When you launch the game, you'll have all new graphics settings (due to the new options.ini), and it'll be in fullscreen mode.  Please test in fullscreen, borderless, and windowed modes, just to see whether there's any difference among them.

If you're still getting lag, please let me know how much CPU and RAM Origin and Sims 4 are using; you can just take a screenshot of the Task Manager if you want.

@A_Fulcrum_Agent  That's interesting to know.  And please take your time.  I'll be around whenever you get a chance to test.

@A_Fulcrum_Agent  Since this is a new Windows install (that's brutal), please run a new dxdiag and attach it to a post.  It should show any errors related to Sims 4, including whatever prevented it from loading.  There may be some info about Bluetooth as well, but if not, I'll ask someone else about it; I'm not great with that kind of thing.

Origin taking up a massive amount of CPU has been reported recently, although the posts are sporadic and there doesn't seem to be a consistent pattern to why it happens, or why it stops.  But putting Origin in offline mode, not just disabling Origin in-game but also going offline, may help.

Some updates.

I had to 100% nuke it from orbit (after moving important stuff from the main drive), and wrote 0s to the drive. Repartitioned, formatted, and installed a 100% fresh copy of Windows.

I had a massive adventure getting the mouse to work at all. As it turned out, the Nahimic service that Asus motherboards install at go does incomplete installs. Once I went and got the Nahimic 3 services and installed them, literally everything stopped happening.

Well, except the Bluetooth mouse not connecting to LTE signals. The random stutters and freezes got significantly better. It's playable, especially with Offline mode engaged.

So...that's what caused it, as near as I can figure.

Here's the DXDIAG though, so we can maybe spot what's up, and provide resolution to anyone else who gets this issue.

@A_Fulcrum_Agent  The most obvious difference is that you're now running a year-old build of Windows.  I haven't heard of any issues with the current build that would explain your issue, but there are plenty of drivers and other software that would have different versions for each build, not to mention how the same drivers would interact differently with each build.  I'm not suggesting you update to 2004 just to experiment, but it's something to keep in mind for when you do eventually need to update.

You also have a slightly newer Nvidia driver, one that hadn't been released when you originally posted.  What's interesting is how new the previous driver was, and yet Nvidia replaced it just over a week later.  Maybe that's because the company is working out the finer details of supporting the new 30-series cards; maybe there was a problem with the older driver.  I have no idea; I'm just suggesting that it's possible this made a difference, since the problem could at least in theory have been related to how the mouse was rendered rather than anything else.

It's interesting you mention Nahimic.  The software occasionally blocks Sims 4 from loading at all on certain systems, usually for a few weeks before some update in the background fixes it.  I've never heard of it causing your particular issue though, or of an incomplete install being a problem.  Still, given how much of a pain the software can be, it's plausible that it was the cause.  You could also try uninstalling it entirely, or at least shutting it down via the Task Manager, to see whether it helps with the residual stutter.

When you do eventually update Windows, it's a good idea to run one update at a time, manually, and test after each one.  Windows will install a number of new drivers along with its new build, and that can't be helped, but if the problem does recur, running the other updates separately may help clarify the cause.

At any rate, I'm glad it's better, if not all the way better.
