anything recommended if having a low fps?

Could reduce your graphics settings or turn on multicore rendering. The downside with that is that some of the Christmas lights will cease to function, sadly.

A portion of the road in front of the bowling alley do not have collisions for vehicles. Half life and simfphys vehicles phase through when trying to drive over.

In a future update the road will have to be clipped. The problem stems from a displacement that doesn't have collision with props it seems.

Can you make a nodegraph for npcs? since you made a navmesh?

why it ourple

When it's purple it feels a little laggy and then when it does the little fade to not purple and its normal lighting its less laggy, I would also say add more spawn locations

Loading up the map I was introduced to the worst bug I've ever seen on gmod: Tree's were just cubes, tree's textures were newspapers, and most of the textures in general were swapped. No idea whats causing this either

Same issue as Dr. Ice, no idea the cause and the weird thing is, with "whereis" all the textures point to a "map.pack" file that only exists when this maps is loaded.

bad argument: #3 to 'Add' (function expected, got nil)
1. Add - lua/includes/modules/hook.lua:31
2. unknown - lua/postprocess/crispylensflare.lua:101

I love the map but I just wish there were more shops and buildings to explore.

My textures are also corrupted as Dr. Ice and Rasmordem are reporting.

I really have no idea about these texture displacement issues. I really doubt it's a map problem, though.

To the left of the right "All dogs on leash" sign, some more clipping issues with vehicles and props in a specific spot

I found the issue and should fix other maps with the same problem. It is not an addon causing it and it is not a hardware problem either, but it is the Game itself.

The "x86-64" branch of Garry's Mod is the problem for the weird textures everywhere. This problem only occurs in this branch, so switch back to the regular branch to fix it. No idea what specifically is the cause in that branch, but switching back to regular fixed it for me.
