I am joining a server that uses TacoScript (which is a rp'script) and this shows in my console when I join.

The problem I'm having is a mysterious series of lagspikes right as I enter the server, I hear the gun reload sounds repeating itself over and over again. The lag NEVER stops by the way, It only keeps spiking until I leave the server.

Some points to consider:

1. It only happens on one server, of 4 or 5 that are using TacoScript.
2. The servers map is rp_outercanals - in which I've already redownloaded the map.
3. Other people are able to play on the server, but not me.
4. I've refreshed my gmod directory, (pulling it out of "steam/steamapps/username/" and making a new one.) But that didn't help.
5. I cleared my Dua folder in cache, and deleted cache after that. Nothing helped.
6. Removed all addons. Nothing.

The only issue that pops up in console is the line - [B]'shaders\fxc\spritecard_ps11.vcs' - Couldn't load combo 6 of shader (dyn=1)[/B]

Any ideas? Thanks! Happy Holidays to you all!
