# B~M : try running video memory on defaut so game controls mem

Well that helped my system a little with a OFPMark score 3347 I have found that not using command line switches has helped my system. The cpu count and thread and memory. Just letting ArmA do it's thing would appear to be better than all of this tweaking. Might just be that the CPU related command switches are limited to quad core as a max and I'm running a Hex, not sure...

those other games the newer ones out use alot of cached enemy ai, no way could they put out 64 groups on a small map all at once in a 3d world. arma2 like old fighters anthology flight sim or falcon4.0 will always eat up memory as will arma2 and expansions because they deal with huge distances and game doesnt use floating point like most flight sims did in the past. the stuttering in flight of jets is i think because no floating point, but maps arent that big so no need to use floating point. on your hard drive make sure it has cached memory set to auto
and cached reserve of 2 gigs at least and set to auto not fixed memory. you wont need to reboot as often
to free up hd space virtual mem. its still a 2d game with a 3d wrapper = huge memory hogs.
remove the 2d grass on proving grounds add 7 town modules and 250 enemy ai spawned in bldgs no slow down. put 2d grass back in and yu get frame hit.

If you look at some the buildings, vehicles, etc you can see why the game runs so poorly, there's a lot of unnecessary details that take up resources. I'm talking about little grooves that can easily be done with diffuse or normal map, but they modeled it in. same with pipes that have indentions on them for no reason, because you never see them anyway. if you want to know the reason, you really have to study the little details. all those things eat away at the resources. you have one poorly optimized geometry, like a small building, and you place that all over the the map to create a town and that's why it lags awfully.

# Foxhound : This topic is not to discuss why this game performs the way it does but to share tips how to improve performance.

Trying to keep within the topic of this thread can anyone suggest a way to enable the game to make full use of the resources my PC has.

6 Cores running at almost 4GHz
8 GB of RAM running at about 1.4GHz
2 modern GPU's with 2GB of RAM
SSD for OS and game files

Given the published recommended system requirements for this game I'm confident that my computer is several times that recommendation. What can I do to enhance the performance of this game? And I repeat my earlier question that is still unanswered. Has anyone build a computer capable of running this game at maximum settings? My CPU could be faster, so could the GPU's. Is unrealistic to hope to be able to run ArmA:2 at more than moderate settings?

# PendragonUK :can they get a sustained 60fps in every situation?
# PendragonUK :Is unrealistic to hope to be able to run ArmA:2 at more than moderate settings?
I suppose it depends on what you consider realistic (or moderate), in terms of this particular application.

If you've spent anytime following similar topics covering this on the various boards you'll have no doubt seen the reports of users equipped w/ Xtreme core CPUs, SATA III SSDs in Raid 0, 24GB of PC3-16000, and GTX580s in trips SLI driving twin 30" displays complaining about their slideslow of 60FPS, while others, remarkedly, are steadily chugging along on 1st gen Core Duos, 7200RPM HDD, 2 gigs of PC2-6400, and an 8x series GPU.

We all have to contend with finding our own happy mediums...and making our own trade-offs.

My post was directed at the poster directly above my post. The rest of you used the topic for its purpose. Sorry for the confusion :-)

Hi All,
First I'd like to say Hi and Thank You to all of you who provide all the great mods and upgrades for the ARMA series!!
I recently purchased Arma2 and OA separately.
Sorry if this post is a bit long...
But recently since I updated both games to current rev's I am experiencing the "black screen of death" more frequently.
I use to only get it on ARMA2 but now I get it on both games.
And adding ACES hasn't helped :).
I can (right alt) enter back into the game but it's a real pain.
I currently run an nivida 9800GTX video card and have a 4 gig dual core processor running Vista 64 .
I have no problems with frame rates just the Black Screen.
After slogging through every post concerning the "BSOD" here and on the BIS forums I have yet to find a good solution.
What would be the best video card I should get to run the game?
I would love to be able to join an online multiplayer group but as it is now it would be impossible for me because of this problem
Any help would be much appreciated.

If the game like most flight sims has a frame limiter, no hardware will make a difference. limiters even the playing field
one jet flying runs 100 fps the enemy runs at 32 fps........somebody has an advantage in a dogfight , guess who? limiter eliminates that advantage. those who can afford the best hardware always have the advantage till complaints roll in then games get patched with frame limiters no more 100 fps.
all of the old jane flight sims had limiters in 1st patches, so many complaints deemed it necessary.
dogfighters are a jealous bunch.................... even frugals world is shut down kinda sad the state of flight sims are in.

Practically speaking, the human eye cannot differentiate past 60-70 fps, so having 100fps isn't that great of a leap from 30fps.

I agree that you are technically correct that said experience tells me that I can tell the difference between 30fps and 60+ Maybe not visually but the way a game feels. We are playings after all not watching a movie, we are interacting with it. There is also the issue of slow down in complex moments of the game. To ensure you computer never dips below 30 in the most intense fire fight it will have to be humming along 90+ for the rest of the time. If like me you like to run games at the refresh rate of the monitor to prevent tearing it's a little more demanding. You have to be able to have hardware that never lets the game dip below, in my case 60fps. This is not something I can not do with ArmA unless everything is turned right down. Most any other game I can happily run the fps up in the hundreds so I can turn on "Sync every frame". The lads in my clan like playing CoD:Bops As you could imagine my PC can play this game with every setting maxed and is happy to run at 60FPS because with frame sync off it has never dipped below 100fps even in when all hell is breaking out. I know it's not fair or right to mention CoD when talking about ArmA, please be aware I only used it as description of why I would want a game to run no lower than 60fps however complex the game.

I do believe the game is getting better, I have found after extensive testing that it runs much better without the command like stuff we all had to use in the past when starting the game. With the additional information that setting the Video memory to "Default" also frees the game of the constraints of telling what to use but instead letting it make up it's own mind added around 10fps to my system in any given situation.

cinco is correct.
the thing is tho that 100fps guy is consistently pumping rounds
and if the other slower machine cant produce the frames to keep up slow guy never saw or knew what hit him.... in a co-op this wouldnt matter, but a 1vs 1 guns only dogfight would or groundwar deathmatch.
removing grass helps just add it to the init line in your mission. dropping 42 enemy grps of 12 ai ? use cacheing script. default setting was something i read in here in arma a few years ago, sorry late joining...
but i started out on flashpoint demo when we used that crack to open game demo up. so ive been around awhile not really a noob. i use to run a flight sim and at end of match it would state bullet round hits and %
framers always had higher % hits, its why they made the patch to keep everybody on a level playing field.
i cant be for sure maybe a developer could answer if the game uses a frame limiter like most flight sims.

after patching i had to practice all over again to get back where i was on the topgun list...

Thanks for all the input, my Frame Rates are fine, no lag,no jitter, just the plain o'l "nivida black screen."
DarkXess,I reread the posts and I did see something I missed earlier.
Adjusting the in game video size to be slightly below the resolution size on my montor.

I did that and then set my video panel to :
Ambient Occlusion = OFF atm.
AF= Application Controlled
Gamma Correction=On
AA= Application controlled
Transparency= off
Texture Clamp=Use Hardware
Pre-Rendered Frames=8
Single Display performance Mode
Maximum Performance
SLI-Force alternate frame rendering 2
Texture Filtering = on
Texture filtering/neg bias=clamp
Quality=High Performance
Trilinear Optimization= on
Threaded optimization=on
Triple buffering=off
Vsync=off
This helped a great deal, I was able to run OA at Max Seetings for almost 1 hour before it crashed to balck screen.
I did a video flush and Alt+ (right) entered back into the game and I was able to run it for about another 1/2 hour before the next crash.

I am still having trouble running ARAM 2, I still get crashes almosst every 5 minutes, even running the above settings
But I haven't given up yet.
Thanks for all the help.
