能看个大概，请高手详细翻翻。
found this on the SimHQ forums, I used it myself, and noticed a remarkable change, maybe it can work for you too.
Basically just delete two files in your My Documents\ARMA folder which are "AMRA.cfg" and "YourName.ARMAProfile". Start up ARMA which will launch with all settings to default. Setup your settings and see the performance boost. Details are available on SimHQ
I just tried it out by backing up my old config files and then deleting them. When you start ArmA, it basically just creates new ones.
The only real difference I can see between them (apart from the fact that all the settings are reset to default) is that the 3D_Performance parameter in the ArmA.cfg is about 10% lower than before. That's all.
I'm guessing they've lowered the value of the game's internal benchmark for 1.14 - I'm not sure if or how exactly that number affects performance, but it's worth lowering it to see what happens. No need to delete your config files.
EDIT:
Just tried playing around with the values a bit. First I set it to just under half of what it was before - result was LOD dropping at very short distance, resulting in low visual quality but overall higher framerates.
Then I tried setting it to 3 times the old value. Result: hardly any visible LOD drops, good visual quality at further distances and also smooother, albeit lower FPS.
Overall I surmise that the 3D_Performance setting has an effect on LOD fall-off. The lower the value, the lower the overall level of detail, but also more switching between LODs. I would recommend playing around with the value, to see what suits your system best.
I'm not on my own computer right now, but I'm definitely gonna try this out at home.
“If you have a low end system, or for whatever reasons might get low fps while playing ArmA, you might want to try this...
Now I have a kickass system and got 40 to 60 fps before and even after the v1.14 patch... but then 2 days ago after playing a session of Warfare with TG, when I exited the game I got a memory dump and a boot to DOS, or whatever that is...
After a hard boot, I tried to play ArmA again and got a error message saying my 3D config file was missing, or something simular... I then went into my "my documents/ArmA folder" where it has 2 files and a couple of folders for missions and mpmissions, saves etc etc...
Well I knew that the 2 "files" (not folders) in there was my confiq files... can't recall the exact names, at work now, the files must of got corupt... magnum something and magnumconfiq something... so I deleted them both... started arma again, and no error, but then had to set my settings/options up again... everything maxed just like before...
So when I played again, I notice fps between 55 and 75... with the 未知单词e max settings...
So after you patch, you might want to try it and see if you get a 10 plus fps boost also.
good luck. ”
从下往上4个人的观点。
第1个人说他电脑原来桢数40-60。有一次当机，重启以后报错说缺少3D config file，这家伙就到my documents/ArmA folder把两个配置文件删了。
重新进去没问题了。所有配置都回到初始的默认状态。然后他重新设置到之前的配置。发现桢数上升到55-75。所以他认为把配置文件删了重新设置可以提高10桢左右。
第2个基本废话。说什么视觉选项开的高，画质好，但是视距近，桢数低；反过来画质差、但是视距远、桢数高。让大家多试试，找到最优化配置。
第3个说删掉My Documents\ARMA folder下的"AMRA.cfg" 和"[游戏ID].ARMAProfile"之后除了原来的设置都没有了以外，没有任何差别。但是他注意到1.14以后的默认设置对系统要求似乎下降了10%。
第4个说他配置：AMD 64 Athlon 3800+ 2,40 Ghz 2,5 GB DDR2 512 mhz Geforce 7600 GT 256 mb 2x Hitachi 80GB 7200 rpm Princeton 19" TFT 60Hz refresh rate。他只找到并且删掉了AMRA.cfg，没有发现桢数提升。但是他发现他删掉这个文件后关掉阴影能够提升15桢，而删之前关掉阴影只能提升5-8桢。
以上就是简要翻译了。据我所知，删掉这2个配置文件会使ArmA恢复到安装后第一次运行的最初状态。也就是ArmA会根据你的系统配置推荐你画质高或者低。我只能说可能对每台机器的效果不同，大家不妨一试。但是之前最好能做备份，一旦删掉，你的各种个人选项设置（包括按键设置）都将丢失。
