domokun 515 Posted April 16, 2012 Last month I upgraded to a 7850 from a 4890. Apart from a 25% increase in framerates, the card draws less power and generates less heat. So I was happy. However last night I tried to activate FXAA by editing the ArmaOA.cfg and changing the parameter PPAA=0 to PPAA=1. Much to my surprise and disappointment this led to a black screen. The menu is visible but the 3d render behind is all black. FYI I'm running 12.3 Cats on Win7-64. Any ideas? Share this post Link to post Share on other sites
maddogx 13 Posted April 16, 2012 What happens if you use PPAA=3? (SMAA) And what is your "PPAA_Level" value set to? Share this post Link to post Share on other sites
domokun 515 Posted April 16, 2012 I haven't trued PPAA=3 but I tried with PPAA=1, PPAA_Level=0 as well as PPAA=1, PPAA_Level=1. Both of these combinations gave me a black screen. I'll try PPAA=3 tonight. Share this post Link to post Share on other sites
virtualvikingx 19 Posted April 16, 2012 I have the same problem for my 6990s. Enable/disable vsync fixes it. Looking for a permanent fix though. Share this post Link to post Share on other sites
domokun 515 Posted April 16, 2012 (edited) MadDog: looks like you're right, only SMAA works (via PPAA=3), i.e. FXAA doesn't work... VirtualVikingX: I tried everything from disabling V-Sync in .cfg, in Cat CC, both, neither and nothing worked So for the moment I'm sticking with SMAA at High (PPPA=3, PPAA_Level=2).

virtualvikingx 19 Posted April 17, 2012 I have to do it IN GAME - switch it on or off depending if the game started on or off. Share this post Link to post Share on other sites
domokun 515 Posted April 17, 2012 VirtualViking: Ah! Small but vital detail there. Thanks I will try again tonight. Share this post Link to post Share on other sites
