Missing Textures for the Mirror and Refraction Issues

[mmmmmmm]

The main thing I can recommend is to simply try updating your Graphics Card drivers in your laptop, as they may be somewhat outdated. If the effect relies on components which are not present on your current driver's software, then that would be the first thing I would try.

Have you also checked and tried altering some of the in-game settings? I believe there are options regarding refraction in there somewhere off memory.

If not, then I'm not sure there's much that can be done. You may opt to try a Steam File Integrity Check in the off chance that there are files missing which provide the effect in SOMA, but I would expect more issues to come up if that were the case.

Have a look at Step 3 here for information regarding updating your drivers, if there is an update available. https://www.frictionalgames.com/forum/thread-30644.html

Thanks for the advice.

I haven't actually updated my Mac in nearly 3 years - I'm installing the new High Sierra OS after missing Yosemite, which should take a night to complete.
