That could be your problem, from what I've read ARMA2 is extremely demanding on the cpu and you really want to be packing over 4ghz
the game isnt badly coded
I got my I5 2500k at 4.7ghz and I get a steady 60fps near constantly.
Remember Arma 2 isn't a crappy game in a corridor, the island is massive, with cities and all sorts, ballistics and everything going on.
Your crappy cpu is holding you back, SLI/Xfire make no difference to fps.
People saying it runs poo because of it being incredibly complex, well explain to me why it runs like **** when i just slap one unit in the editor with no modules or anything... there is nothing going on the in the world, just me running about watching my frame rate jump all over the place for no apparent reason.
Its an old engine and it shows, BIGTIME.
If you need a 4ghz CPU and SSD hard drive to get a smooth experience, its badly coded
If walking around in an empty world in the editor with no other units or scipts running causes your frame rate too fluctuate massively, its badly coded
If simply walking up to an area with a few building causes huge frame rate to drop massively, its badly coded.
If texture pop in happens all the time, its badly coded
Don't even get me started on the laughably bad netcode where players warp all over the place at long distances and where its impossible to sit in a vehicle controlled by someone else and move around smoothly...
Its a poorly optimised game even when you consider the scope of it, there is no two ways about it.
i cant speak for the OP but all this talk of "its got to calculate stuff going on miles away etc" doens't explain why i get massive frame drops just walking about an empty world in the editor.
vegetation and buildings = frame rate crippler
If your getting warping then your server hasn't been setup correctly.
If your getting texture pop ups install 1.59 patch
Why is a game that pushes the boundaries of hardware "badly coded'? Would you be happy to play the Source engine forever more? oh wait... that was considered badly coded when it was first out.
Just because it doesn't run on your crappy machine doesn't mean its badly coded. Maybe, given the things the RV engine does your cpu just doesn't cut it.
how do you turn off HDR ? its lowest possible setting is "normal" isn't it ?
surely you must get vegetation pop up as it only renders vegetation within a certain distance, thus as you run about you will see the vegetation drawing in ?
I don't get veg popup they fixed this in the 1.59 patch. Could be your drivers?
I can't check the HDR stuff as I'm on my mac atm.
