Whenever I download this mod, it seems to either, 1 crash my game or 2 not allow gmod to start. Along with those two things it frequently will cause huge FPS drops when I use specific weapons, bombs, etc.

Sorry, I don't know much about making Gmod run better.
I just threw some common commands which are suppose to help with fps into a simple execute thingy.

so I was on gm_construct_in_flatgrass I went down a staircase (Not into the dark room) and I came back and the water reflected it. I changed maps but it did the same thing with the same staircase have any clues to why this happens?

It gets super dark on my hands when this is on so i cant see my weapons

The TFA Silenced has a FPs

The cubemap/reflection system seems to be broke, if you want i can send screenshots/pictures.
