Re: White spots, marks, patterns, markings all over Sim
@queenlypeanuts This is usually a custom content issue, and it could definitely be caused by cc tattoos, even though the pattern is widespread.
Before doing anything else though, are you running the game in laptop mode and/or is the uncompressed sim textures box unchecked? Please try checking that box and disabling laptop mode, at least temporarily. Even if your computer can't handle the higher settings, it's useful to know whether this helps.
If it doesn't, or you can't play with those settings, try using the 50/50 method to sort through your custom content.
