You know when the screen shakes(minigun/saw/nades... stuff), the edges just dont shake in the same step as the textures, sometimes it cover an idle nade and last but not least it drop a lil FPS. These are objective facts, and in my personal opinion it looks crap, btw my own Soldat run in the lowest of the low in Config.exe.
The rly strange fact is that edges dont cover some polies, idk why.
