Old World Blues causes some serious slowdown

[Douchehat]

I can run the game on high at a pretty solid framerate (only suffering minor stutters with increased spawns and faction wars on the IWS mod, but that's to be expected), but since starting Old World Blues, the Robotic Scorpions' laser attack from their stinger causes an engine hiccup, without fail, every time it fires. The Sonic Emitter sometimes causes a similar stutter, but only when there's a ton of other stuff going on. Regardless of location and other things to render, however, I have encountered a single Robotic Scorpion in an otherwise vacant small room, and the stinger attack still causes a stutter.

 

Is there something I can do about this? It makes the game somewhat difficult to play, given the ridiculous amount of scorpions I have to fight.

Try toggling grass with the console command TG and see if that helps with the scorpion. Then if that works I can tell you what you need to do.

Seemed to help at first, but then I went outside and ran into some scorps, and the laser effects resumed stuttering.

Tinker with the light settings, turn off HDR and BLOOM if they are on. Reduce exterior shadows and for the love of god- don't use vsync.
