Wow, der Support hat mir geantwortet, das ging aber sehr schnell!
Mit Erlaubnis würde ich die Antwort hier gerne posten...
Dear [...],
please try the following:
1) Forcing Arma 2 to detect less than 4 GB of memory. The maxmem
parameter often does not work. Please adjust memory in msconfig
instead: Type msconfig in Start menu and press Enter, memory settings
are located under Boot -- Advanced Options. Please tick "Maximum
memory" setting and set the desired size in megabytes (i.e. 3072). Note
that this will require a restart. You can return to 12GB at any time by
unticking "Maximum memory" (and rebooting).
2) Downclocking your Phantom GTX580 to default nvidia factory settings.
Arma 2 can put extreme stress to certain parts of GPUs. It is possible
(improbable maybe but possible) that slight factory overclock of
Phantom is just enough for the card to produce artifacts in A2. Default
clocks for nvidia reference GTX580 are 772 MHz core and 4000 MHz
memory. You may try to downclock even more and see if it has any
effect. To downclock your GPU, use either any software Gainward has
provided you with, or MSI Afterburner (despite its name it works for
every nvidia GPU).
Other than this there is really nothing more I can think of you haven't
tried already, maybe a strange operating system issues (but then you
would probably experience glitches in other games as well) or
overheating problems (then again, other games would probably be
affected). Let me know if the abovementioned workarounds produced any
results.
Meine Geschriebene Mail:
Dear Sir or Madam,
I've got graphical issues with ARMA 2. This problem appears mostly in villages / cities and is not acceptable for gaming. This glitch seems to be exactly like this: https://dev-heaven.net/issues/23716
(see pictures above in the link)
This Problem is very easy reproducible for me: In the main Campaign (Red Harvest) of ARMA 2, I have to choose the "Red Harvest" MISSION. The Mission starts and then the blurry textures appear. Sometimes, I first have to walk downstairs and then they appear when I'm out of the building and I'm watching in to the grass.
Game is: Arma 2 Black Edition (without Addons / Mods etc.)
I've done the following with NO results:
+ Updated all drivers (+nvidia driver)
+ installed new nvidia beta driver
+ changed in game settings in graphics menu to low
+ changed VRAM settings to Normal or Default
+ installed newest patch 1.11
+ deleted the ARMA .cfg file, restarted the game and left to its defaults settings: same problem appeared again.
+ Changed driver settings itself to low and high, after that with no results, I left it to "let the program decide" ... and again: No luck.
BF3 and other games runs outstanding.
SystemSpecs:
CPU: Intel Core i7 990x Extreme
Graphics: Geforce GTX 580 Phantom - 3GB VRAM
Ram: 12 GB Corsair Vengeance
SSD: OCZ Vertex 3 128 GB
OS: Windows 7 Ultimate 64bit, ARMA 2 is installed to the "C:/Program Files (x86)/ ..." folder.
All system components are NOT overclocked / modified.
Used Screen is 1920x1080. Changing the resolution to a lower one didn't helpt.
I hope it's possible to fix this problem, I'm a big fan of ARMA since the first Operation Flashpoint!
Best Regards

Lösungsätze 1 + 2 habe ich tatsächlich noch nicht ausprobiert. Wird in nächster Zeit gemacht. Wobei ich mit Lösungssatz 2 am besten Leben könnte
