The fog with the thruster and the flaming ships are the most troubling, as explosions and other stuff don't happen that often, I guess they are managable.
But the fog reducing the frame rate everytime I tap the thruster is a pain.
But hell, I just replaced the whole FX folder with the one from 86.0, works kay now.
I searched there... Sadly, only the latest version of Disco 4.86 is there, titled " discovery_4.86.0_jul12.zip ". Which installs all the new effects alongside with it, unlike the older versions of 86.
I guess I will try 4.85 FX folder... However, this method made me crash once in a while. Probably when the comp couldn't find a replacement for the effects that were added with the latest versions. I am just wondering if there is a safer way for me to just replace those effects (namely: flaming ships, thruster smoke, explosions) with the vanilla ones.
