The default ATOC level 7 gives me a smudging effect on higher LoDs of trees in Takistan, making them look like very low quality:

zoomed, same position

Specific to ATI only? Any Nvidia user?

Not so much extreme, but also an 'oil-painted' effect on Plants, especially on LODs after the first
All on a NVidia GTX295 !

Yes, it sometimes happen to me too. Nvidia GTX580, newest WHQL drivers.

I thought this problem will be solved by changing ATOC from 7 to 0, but its still there. There is also noticeable performance decrese for few seconds when aiming with scope(for example with USMC Designated Marksman). Try to aim to area with high density of trees and bushes. You should see LOD changing and very noticeable FPS drop. I have this FPS drop when aiming to such areas, with GTX580 and so I dont think its because of slow HW.

PP effects disabled, terrain on normal, shadows on normal, AA on normal and everything else very high. VD is 2011m.

  • Status changed from Assigned to Resolved
  • Target version set to 1.60.87580
  • I am using deleted (CO (A2+OA))

Latest ATI/AMD drivers seem to have resolved this issue, so I can use AtoC=6 (which resolves the grass moiree/raster effect, opposed to 7).

I actually resorted to AtoC=2 because on ATI cards the Chernarus trees still look fugly.
