Both slowing and energy drain missiles produce a nice looking but very difficult to calculate effect, leading to massive drops in fps on low end Pcs. Please consider changing the visual effect into something less flashy. I personally cant use them because d pull myself into the nether regions of fps.
But then again I’m playing on a laptop, so I can’t really complain.
Odd, when I was playing with my old graphics card I didn’t run into this problem, but I suppose it would be an issue if you run into an ecm that spams Energy drain missiles or a new-ish tackler player.
