Description

The new ATOC feature in latest BETAs set automatically to 7, yields a funny rasterize effect over homogenously lined grass or bush object:

Same here

GTX295

Reporting the same on GTX260, version 1.59 final (please add, bug is still unsolved). I know several people with the same problem, which started with adding of new AToC render.

Please always include your AToC settings and AMD/NV driver version.

Updated by 567765 almost 4 years ago

AToC=7, tested on GeForce/ION Driver v266.58 and GeForce/ION Driver v270.51 beta drivers

Updated by Dwarden almost 4 years ago

please note each card generation and drivers could slightly differ on results (dithering, smooth gradient transit etc)

it should be supported on all
AMD.ATI GPUs since 95xx serie and newer
NVIDIA GPUs since Geforce 7 and newer
Intel shall support ATOC in SandyBridge GPU (GMA 2000 and up) since this month drivers ...

yet also various hardware vendors operate with AToC differently, it's always best to experiment with settings

plus i noticed several people reporting different quality of AToC (rasterizing, transits) with different levels of AA

Yeah, so it's unclearly why to include so untested feature in "stable" patch.

I'm also disagreeing of the practice to just "slip it in", without proper GUI elements to disable it, so to notice for the novice user. He just thinks "oh dear that patch fubar'ed my game" when he might a) notice that it's going slower and b) sees (like me) worse quality.

If someone uses 1.59 (or 1.58 with Reinforcements) "out of the box" (i.e. first patch after he bought it new) and sees low quality vegetation and where it would look fine it's rasterized, then his first guess might not be, that he has to manually tweak settings in the arma2oa.cfg, specially if he doesn't fancy forums.

This might give bad user reviews.

Exactly same problem

Arma2 OA 1.59
Geforce 9800 GTX+
drivers 266.58
AToC=7

Updated by Mauser almost 4 years ago

I have the same problem. Most noticeably on small bushes in OA with lower AA settings.

Game version: ArmA2 OA BAF 1.59
Graphics card: ATI Radeon HD 5850
Driver version: 8.821.0.0
AToC: 7

Updated by Fireball about 3 years ago

Can be workarounded with AtoC=6.

Nope.

Updated by Fireball about 3 years ago

Certainly works for me, since the moiree appears on grass only. the missing bit on the '6' setting means that AtoC is not applied to OA grass (and for Chernarus I haven't seen anything alike either).

Only the trees on Chernarus might show some moiree if you look really closely, but its not that bad.
