The map RP_Bangclaw is quite laggy on low-end PCs, even in its unhaunted state. Making a map "haunted" results in the FPS dropping even lower.

I have tried to optimize the map in certain ways to increase FPS, this can however still not be enough if your PC is on the lower end.

There is a way to increase your FPS in Garry's Mod using certain console commands.

"gmod_mcore_test 1; mat_queue_mode -1; cl_threaded_bone_setup 1"

Copy this line (without the ") into your console. If you have a multi-core PC you will most likely have more FPS.

You can also try downloading this addon for increasesad FPS https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1169579845

If all this dosen't help you can try disabling addons, as having loads of addons decreases your FPS as well.


Hope this helps!
