Please make sure you also try the last step mentioned in the FAQ:

4. Disable other addons (then restart the game, just in case). This map requires more memory and processing power than the average GMod map, so combining it with other performance-heavy addons can lead to poor performance. Additionally, some addons may not be optimized to work with a map of this size.

Temporarily disabling everything else (and I really mean everything) is the best way to narrow down the problem. If the map still performs poorly after doing this, it might be a hardware issue, in which case you should post your PC's specifications here. However, if disabling everything else does fix performance, then you can re-enable your addons in small groups until you find the one that was causing the issue.

If you need more help, let me know.

my pc runs on decent hardware. disabled non optimized addons, still at f**king 0 fps

Again, you really need to try disabling everything except for the map. Even just once.

This is an essential troubleshooting step, not a requirement for playing the map. I can't help you otherwise.

Disabled all my addons, now when i boot up the map the game crashes

Make sure you restart the game after disabling other addons. If the crash still occurs after that, try switching from the regular version of GMod to the 64-bit branch (or vice versa).

im on the 64 bit branch and restarted. freaking wiped the map off my game when it was loading and crashed

Sorry to hear you couldn't get it to work. If you create a collection of the addons you were subscribed to when you were experiencing poor performance, I'll see if I can reproduce the issue on my machine some time.

i have 801 addons that i have. it would probably f**k up the gmod steam community servers if i did upload a collection

801!??!?!??! NO WONDER WHY

Honestly I have the same problem but I have 342 addons. most of that being models and NPCs. I just hope that someone releases a variant of this map that is somewhat "playable" because this game runs at 25 fps on my somewhat decent pc. I disabled all my addons and did the last instructions on the troubleshoot and I couldn't find the addons that was causing the issues. I made a collection of all my addons just in case my friends join so they can subscribe to my addons.

I subscribed to your collection and ran a Lua profiler to identify the bottlenecks. This is a bit technical and I'm not gonna do it again, so please bear with me.

Have a look at these results for the client[i.imgur.com] and server.[i.imgur.com] The rightmost column shows how much time is spent executing code in various Lua files over a period of 20 seconds or so. The higher something is shown in this list, the more it's impacting the frame rate, so this tells you what to focus on.

To find out what addon a file belongs to, look at the Path column. If the name doesn't look familiar to you, you can open the in-game console (Shift+Esc) and enter the whereis command followed by the path. For example:
In this case, it should tell you that this file belongs to the Followers Mod addon. In other cases (for example with lua/includes/extensions/entity.lua) it won't show an addon name, which means that it's part of GMod and that you can probably ignore it.

If you uninstall or disable the top 10 to 20 or so addons that you can find this way, you'll likely see some significant performance gains. The biggest offenders in your case seem to be the Followers Mod, SCP:CB SNPCs and BSMod KillMoves addons. I don't know what these addons are doing under the hood, but they don't seem to be optimized for a map of this size.

I just disabled the SCP addon and unintalled the followers mod. the performance greatly increased to a 45 fps. not done yet but I will see what happens in the future.

Glad to hear that. If you inform the authors of those addons, they may be willing to look into the issue and fix it.
