Re: DEP Crash Despite Totally Disabling DEP
@TurtleShroom There is a lot of misinformation in the Steam forum post you've linked. First of all, Sims 3 is already Large Address Aware, meaning it can use close to 4 GB RAM on its own, with no patch needed. This has been true since 2010. The number you changed refers to the script heap, and the initial value is 20 GB. It's best not to mess with that number, or to revert any changes you've made. Sometimes the change doesn't have any measurable negative effect, but if you're getting crashes, it's best to return the game to vanilla form, at least for the moment.
On that note, please run the Super Patch to restore the default versions of the game's program files. The direct download link for the Super Patch is here, under "Cumulative Base Game Super Patcher":
While your graphics card is recognized now, other changes you made might also have negative effects, and you can add your GPU to the appropriate files again without too much trouble. The information about VRAM in that post is also inaccutare—TS3 can only use 800 MB of video memory no matter how much your card has. Your deviceconfig also reflects that the edit suggested isn't quite right; I can write out what you need to do later, if you want. The VRAM override value the game assigns sometimes does not usually cause crashes itself.
The Crash Log Analyzer is also not always accurate. Other than an out of resources report, its results are generally not reliable. Better is Windows's Reliability Monitor, which will list crashes and other errors related to the game (and anything else). Hit Windows key-R and enter "perfmon /rel" without quotes, and you'll see an overall chart as well as entries for each day. Please look for any crashes that mention Sims 3 or its launcher, as well as any entries with timestamps that correspond to crashes. (You may need to look at the details to get a true timestamp; sometimes the one in the overview is delayed.)
For any such entry, please click "View technical details," copy the information, and paste it into a text document. (Notepad is fine.) You can attach the text here just as you did with your dxdiag.
And please test in a clean game folder, as in, move your entire Sims 3 folder out of Documents\Electronic Arts and onto your desktop. Play in a well-made EA world like Sunset Valley or Twinbrook, and let me know how it runs in a vanilla state.
