All colors look wrong and distorted, some playermodels even invisible

Hey all, first off, everything looks kinda like this, sorta distorts to other kinda right colors when walking around though, it kinda looks like my GMod’s been bumping some ranky 25I-NBOMe behind my back…

You can even see how the utilities menu thingy is all messed up and it’s showing some sort of string instead of the right menu title thing to show… I don’t know, I already verified gMod twice, (first time it dl’d a really small 496 byte-sized file) but I’ve frankly no idea what to do to fix it. While playing ttt some playermodels are even invisible (i presume they are the default CS:Ssy models and server custom ones like assassin’s creed, terminator etc show up but without animations, just both arms extended and legs kinda spread too and they all walk all without moving a single limb.

Help?

Also clicked on Update Video Drivers and got this:

Update: Before posting this I made sure to read the posts at the helpdesk, checked my GMod mounts, and played a little game of CSS (i had just downloaded it because it was missing first time i tried to play ttt in a while earlier, which is what sparked the whole issue) to make sure the CSS models were working, then entered GMod and started a little sanbox on gm_flatgrass to test the models and such… What I saw made my jaw just drop and give up any more attempts and convinced me to post this.

Now yeah, help?

something is very wrong, go to the common file under steamapps, and delete the garrysmod folder. Let steam redownload it

It is done.

Did it work?

In about an hour we’ll know. It’s still redownloading.

Alright, I can confirm I was on flatgrass playing around with no missing textures. Then I went thirdperson and fired an RPG at my feet and the game crashed. I guess it works.
