And the white snow effect magically disappeared! So doing some tests I discovered that the "high" level is what causes this: both "normal" and "very high" are immune (very very light presence of flecks with very high, almost unnoticeable. they appeared just on a tree when I was very near). All without the betas. Hope this helps! very interesting find , i do wonder why High would cause it while Normal (4x) nor Very High (16x) would ... maybe something wrong with AMD 8x AF ?

BasileyOne 10 Posted July 28, 2012 well, well-know that Arma2 seriously CPU-hungry, som you GPU performance wouldn't be issue, unless it something like GTX430/HD5450. basically only AMD slightly benefited from GPU OC, cause they bottlenecked by [saturated]ROP's/redering backends/fillrate in Arma2[especially with HUGE viewdistances]. crazy tip: try temporally[in e-shop. or be a guest to you friends with such GPU in PC] 6Gb edition of such cards. would be nice to know how it perform ingame too :) Share this post Link to post Share on other sites
erupter 1 Posted July 28, 2012 I made a new discovery: there are still problems with AA. The problem now is that AA effectively dithers textures. I don't know if it's really so, only that the final effect is of lightly dotted textures. I mean you can see almost transparent dots where you expect transparency of the texture.this in fact happens the most on trees and grass. No AA means no dithering. AF has no effect on this. I results in using FSAA high with medium sharpening. I also noticed that the vsync may have problems too:I had it on from the game options and was having severe input lag. Disabled it and now the lag is gone (and I'm at almost 90fps!). I want to add that I'm positively sure that it's a game code problem: the system has been freshly installed, components are newly bought and modern games (battlefield 3) and benchmarks (unigine) don't have any problem whatsoever.

I'm almost sure the problem is the AA not the AF,AF only happens to limit AA's problems.see my previous post about dithering.
