"Objects" setting texture changes

puzzlezaddict​ Is it really? I'll get on to a reinstall in a sec so thanks for the heads up! I have played the game on ultra in the past but I find my card does get a touch hot, it needs an upgrade at some point. I cleaned it no too long back and try and keep on top of that too. I also have all the packs so I guess I'm wary of playing on too high settings for prolonged sessions

ukbucket​  Your dxdiag is full of crashes of the graphics driver.  I don't think this would be the direct cause of what you've described, but the issue should be addressed regardless.  And if the driver is the cause of the Sims 4 issue in general, reinstalling it should help.

So please do a clean uninstall and reinstall, as described here:

I will say though that there's no reason your computer can't run the game on ultra graphics settings.  If the GPU is a bit hotter, that's not necessarily a bad thing.  If it's actually overheating, say, if it gets to 80º, then that's different.  But in that case, I'd suggest checking the GPU's fans and the case fans as well, since Sims 4 shouldn't be able to push this graphics card all that hard.

puzzlezaddict​ Thanks for the reply! I've attached my dxdiag and a couple of screenshots, you might have to zoom in a little to see the differences, its much more noticeable in my game. 

ukbucket​  I haven't seen another report of this, but that doesn't mean it isn't happening.  It would be helpful to see a couple of screenshots from your game, and a dxdiag as well.  Click Windows key-R, enter dxdiag in the run box, wait for the scan to finish, click "Save all information," and save the file to your desktop.  From there, you can attach it to a reply using the paper clip (Attachment) icon included with the other formatting buttons.
