@DanSherwind There's a lot here worth commenting about, so I apologize in advance for the wall of text that's about to come at you.
First, the simple part: I can see in the log where the crash happened, and it was accompanied by a large spike, more than 4 GB, in virtual memory usage. Physical memory was steady until it dropped a few seconds later, as the game crashed. Unless you had another program running, that's Sims 4 reaching for an unreasonable amount of virtual memory, for some unknown (to me) reason. If you'd like to poke at this particular issue more, let me know. This might just be the game in all its messy glory though.
More urgently, your Toshiba drive is at 22% remaining life, and hwinfo picked up a drive warning and eight reallocated sectors during the run. (The log also contains a couple of values for that drive that should only increase as you're logging, but instead they reset to zero. I mention this because it's odd and a sign that something is not working properly with the drive.) This essentially means the drive is in danger of dying, although that could be months away. But it could also happen soon, so now is a good time to back up any essential data on that drive, and you probably want to start shopping for a replacement.
You could run chkdsk on the drive, which will flag and reallocate bad sectors, in addition to giving you an overall count so you get a better idea of what you're dealing with. However, at this stage, there's a small but nonzero chance that running the scan will cause further damage, so back up your essential data first. If you do decide to run it:
- Hit Windows key-X and select Disk Management, and confirm the drive letter assigned to your 1 TB Toshiba drive, listed as F in your dxdiag
- Hit Windows key-X
- Choose either “PowerShell (Administrator)” or “Command prompt (Administrator),” whichever option is offered
- Inside the window that appears, copy and paste "chkdsk /f /r X:" without quotes, and enter, where X is the drive letter currently assigned
- When the scan is done, use this guide to find the results
- If you'd like me to take a look, attach the results to a post
To the main point, that your computer's Sims 4 performance is far below where it should be: there's no other obvious reason why this would happen. Your processor and graphics card temperatures look fine, the power supply is fine, and I didn't see any other red flags. While the stuttering may be partly due to the game itself, it's clear that the GPU is actually being underutilized to a significant extent. It wasn't even running at its expected clock speed for most of the time you were playing. Hwinfo picked up your framerates, which were all over the place but clearly not capped, which would account for the low readings, so there's some other reason your card isn't working harder.
From the drive activity, it looks like you have the game installed on the Toshiba drive, which could in theory account for the problem, at least indirectly. However, I think the issue might be more about Sims 4 not being optimized for higher-end hardware. This is not to say that it always runs like this on faster graphics cards, and in fact I think this is the exception. But I've seen it happen before, and in the most recent case, running the game at a higher resolution increased the workload for the GPU to expected levels and made the game run somewhat better.
So if you're up for a bit of an experiment, there are a couple of settings to play with. First, open the Nvidia Control Panel's Program Settings tab, and for TS4_x64.exe, set Power management mode to "Prefer maximum performance" if it's not already using that setting. See how the game runs. You don't need to run another hwinfo log—your in-game fps (leave it uncapped) will let you know whether this makes any difference.
If that doesn't help, again in the Control Panel, under Global Settings, set DSR - Factors to 2.00x, or as close to that number as is offered. Then choose the highest in-game resolution available (it's with the other graphics settings). Please try playing like this, again with fps uncapped, and use hwinfo to log the session. This should at least clarify whether the low workload from Sims 4 is in fact contributing. Rendering four times the pixels should max out your card or come close.
If you want, you can try the lower DSR settings as well; perhaps the game would run better with a factor of 1.2 or 1.5. But I'd like to see what happens at 2x first.
