its been a while since i played siege but i noticed the cloaking effect was a little different. I own a 9800 pro and the cloaking used to look like a cool predator effect. But now, after reformating my hd and installing JA again, the cloak looks flat. 
 Is it suppose to look like this? I use the 1.01 patch btw.
  
 
  
  
    In console:
 
 cg_renderToTextureFX 1 (to get the predator effect)
 
 Or...
 
 cg_renderToTextureFX 0 (to get the flat effect)
