For nvidiots with sli.
Ive tried all the tips eg. " rename to "arma.exe" forcing off vsync , turning off tread optimize, lowering AA.
Now im getting really nice results using evga sli enhancement patch (just by modding the import readme file)
All my settings in nvid control panel are norm "high quiality" using sli. Works well for my dual 8800gtx 1730 XPS lappy too...
thread opt and Vsync on "no tearing what so ever". much more smoother gameplay staying at the generic vsync'd 60fps.
I just edited the readme file, tried loading in sli modes and configs in from other games. It turns out Crysis warhead code added on works best. "ironic considering its supposed to be the dx10 glitter king, I suppose the dx9 profiles are suited well for arma... Ive tried most of the other games sli modes and this was the best I found, perhaps adding more or less significant setting id's would help, the more people out there trying the better imo.
Just took all of the arma2 sli profile, put in "arma2oa.exe" as the executable then just added the extra cyisis warhead under it. Arma2 profile helps allot, but adding the warhead was way better again...
Everything maxed out. 8xAA on game gui, (nvidia enhanced Q8xAA). Range was set out to 3kms, seems to do 4kms just fine aswell.. (1.6 kms for lappy all set on high "not very high")
This was done with two gtx480 in sli
I done this rather than going through the rigmarole of updating to betas, bit more too it for us steam users sometimes...
