And here's the mount.cfg text


//
// Use this file to mount additional paths to the filesystem
// DO NOT add a slash to the end of the filename

"mountcfg"
{
"ins2" "C:\Steam\steamapps\common\insurgency2\insurgency"
"cstrike" "C:\Steam\steamapps\common\Counter-Strike Source Dedicated Server\cstrike"
"tf" "C:\mytf2server\tf"
}

This looks like your GMod is running in DX lower than 9. Try forcing 9 using cvar/command-line-option https://developer.valvesoftware.com/wiki/Mat_dxlevel

♥♥♥♥♥♥♥♥♥ that worked, thanks so much.

Now I gotta sort out this ammo issue (can't pick up ammo and givecurrentammo doesn't work either). I've tried the remedy you offered on the sticky but that doesn't seem to work either. Should I purge my addons?

purge addons with same ammo types as those that dont work for you

Found out that the magazine system addon was causing some problems but after deleting it, it's working fine. Thanks for all your help.
