19:48:41 Chickenfeed Does anyone else get huge FPS drops when scoped in?
19:48:42 Chickenfeed On chernarus
19:48:52 Kenwort yes
19:49:30 Alwarren Is AA enabled?
19:49:33 Kenwort turn off post process effect
19:49:36 Kenwort that will help
19:49:56 Chickenfeed It's already off, and I have AA on normal
19:50:09 Variable there's is a drop, I souldn't call it hugh under any circumstances. it depends on the power of magnification, and the viewed fov
19:50:15 Variable woudn't*
19:50:28 Chickenfeed Well, it becomes really sluggish. Makes it difficult to aim
19:50:45 Varanon Chernarus ? Or all islands ?
19:50:56 Chickenfeed I've only noticed it on chernarus
19:51:06 Varanon I had it on Chernarus, until I set the AtoC=6 in the config file
19:51:08 Alwarren Do you have AToC enabled?
19:51:17 Kenwort it's because of the grass
19:51:22 Alwarren I have... yeah... I have it on 6 too, that cured my problems.
19:51:23 Chickenfeed AtoC?
19:51:38 Alwarren AToC=6 disables the grass rendering.
19:51:56 Variable what's the downside Alwarren?
19:51:49 Alwarren It's My Documents\ArmA 2\ArmA2oA.cfg
19:52:06 Alwarren The grass is rendered without AToC
19:52:08 Varanon It no longer uses the AtoC effect for Cherno grass
19:52:13 Varanon Only Chernarus, not Takistan
19:52:24 Alwarren Yeah... Takistan has different plants and grass
19:52:41 Varanon http://community.bistudio.com/wiki/arma2.cfg
19:53:07 Varanon Check the AtoC entry, it explains what it does
19:56:21 Chickenfeed Changed it to 6, I'll see if it works
19:56:37 Alwarren Good luck [img alt=Description: https://imo.im/images/blank.gif width=1 height=1]http://ciahome.net/forum/file:///C:\Users\Roi\AppData\Local\Temp\msohtmlclip1\01\clip_image001.gif[/img]
19:57:06 Variable And what do you do with the ingame AA setting?
19:57:21 Alwarren Just keep it. AToC is independent of the setting, it just requires that AA is on.
19:57:57 Variable ok, seems like default AToC is 7
19:57:59 Alwarren yes.
19:58:27 Alwarren For me, that always gave slowdowns when scopting. Since I turned it to 6, I don't have the problem anymore.
19:59:14 Variable which means you don't have AToC on grass
19:59:31 Alwarren Yeah... but the difference on the grass is hardly noticeable. It makes a difference on trees, though
19:59:51 Varanon On Chernorussian grass, but it doesn't show that much there anway... the biggest difference is with the trees, they no longer flicker like hell with AtoC
20:02:23 Variable I see
20:02:43 Variable I'm gonna put that conversation on the forums, for the sake of future generations
20:03:00 Alwarren I surely hope future generations can play ARMA 3 already, I didn't want to wait THAT long Big Grin
20:06:10 Chickenfeed That works much better, thanks alot!
20:06:19 Alwarren You're welcome
20:06:20 Varanon (Y)
Seems to have improved my FPS on this ghetto PC, but the A2 grass definitely is uglier.


I also run the new PPAA that was introduced in the betas, you should give that a try.
