This is the current gm_construct with almost all the removed features ported back from the GMod 13 beta period!
In 2012 I was following gm_construct 13 progress, testing, saving links, and at that time I even ended up getting and publishing an unmodified version of the map to preserve history. Unfortunately I never liked that some content was removed and now, 9 years later, I finally decided to get my hands dirty and do something about it!
Obviously I needed a little artistic freedom to blend all the pieces together naturally, consistently, since we have many unfinished or unrefined parts mixed with map resizes, but I didn't leave important features out! Each version got carefully looked, and even the doubtful things are back! I also took the liberty of integrating some improvements.

Features Explained
Some evidence that I'm playing GMod since 2007 and that in fact I joined GMod 13 beta period: https://youtu.be/AnfcF4fSOGw (04/12/12) https://steamcommunity.com/groups/GMBR https://steamcommunity.com/sharedfiles/filedetails/?id=133957053

So there's no such thing as "real" gm_construct 13 beta, what we have is an evolution which ended up in the map we all know and love.

Missing textures
Check if disabling your addons solves it, some can cause reflection issues.
You can also disable reflections:

Low FPS
gmc13b has lots of new shapes to render, so even with optimizations it's still heavy. However, the biggest villain is the 3D Skybox, which loves eating FPS. So you can gain FPS by disabling it:
