I just tuned my OC settings. RAM is now running @900 (1800) Mhz and CPU @3.78Ghz - and it changed a lot... (see above) I still think (just my opinion) ArmA2 has got a big problem with caching things and loading them from harddisk to the grafikcards RAM. The 5th Test of ArmaMark2 runs horrible at my system. Only the 2nd run gives me "OK" results but if the engine starts to render the trees my system sucks and framerate drops below 10 while the Harddisk starts to I/O like hell. Would be interesting what happens if someone with 12GB RAM or more stores the arma files in a ram disk... hmm maybe I am the stupid one buying 6 more GB of ram... :) ---------- Post added at 12:58 PM ---------- Previous post was at 11:36 AM ---------- I tested ArmA2 with a Ramdisk. I was only able to create a 4GB Ramdisk (my system has got only 6GB RAM) so I had to use "mlink" to create symbolic links from files located at the ramdisk to my arma2\addons folder like this: c:\mlink c:\arma2\addons\structures.pbo f:\structures.pbo I moved some of the pbo files to the ramdisk: buildings.pbo buildings2.pbo dubbing.pbo misc.pbo misc2.pbo misc3.pbo plants2_Bush.pbo plants2_Plant.pbo plants2_Tree.pbo Roads2.pbo structures.pbo I am not sure if these files contain the most important files for armamark2. So some content of ArmA2 was now loaded from RAM not the SSD. I hoped this would speed up things - BUT it didn't. Score ~ 6910 Also the laodlags still existed.

Hi, my ram is running at 720Mhz what is known as 1440Mhz. This is a kind of marketing. The real clock is 720Mhz but it is shown as 1440Mhz. You could use CPU-Z to see your real values. ArmA2 is a directx9 game. So even if you use Windows7 (what provides directx11) you will need to update/install the latest version of directx9 otherwise ArmA2 will give you an error (http://forums.bistudio.com/showthread.php?t=77880). I hope this cleared things up? Regards, Flo

Hmm our systems are very similar but mine is not able to reach the 40 FPS in the 5th test. My ATI HD 4890 has 1GB RAM what should be an advantage in this test. Did you decrease "sceneComplexity"? My system drops to 10 FPS in the 5th test when the distacne is reached to render all the trees - so no chance to reach 40 or more FPS. At which mhz is your RAM running? Did you OC the grafikcard?

I hope further patches will solve that... Regards, Flo

Just get microsofts sysinternals process monitor and watch the crazy amount of I/O's ArmA2 does while playing. ---------- Post added at 03:30 PM ---------- Previous post was at 03:27 PM ---------- Strating crysis in 32bit and 64bit mode does not show this effect. Both executables use the same amount of memory...

Yes much more RAM CAN be used by a 64bit application (about 8TB?). So for example my system has got 6GB of RAM but ArmA2 uses only about 1,2GB of my RAM. It could use all my free RAM to cache game data what would lower those ugly lags while moving over the map because of all those reloads from the harddrive. 32bit was yesterday...

The server version has nothing to do with the client version. So even if the client is 32bit and was never planned to be a 64bit application the server could be a 64bit application. Yes directx10 would be a major change but directx9 is so 2002 (!)... Listen to the features of directx10 - some of them could help a open world environment a lot... Arma2 already has got a lot of "directx10 features" like soft shadows and sunrays but directx9 does not support those things from scratch. So some of those effects might be rendered by the CPU. This could be why the GPU is not that important for Arma2 and the GHz of the CPU increase the performance most. So moving those effects from the CPU to the GPU world increase overall performance a lot - imho Recoding the client from 32bit to 64bit is not that big deal and should be on the roadmap.

Hi Suma, I am no coder but as far as I know there are some good reasons for directx10 and some of them are in ArmA2 but maybe they are CPU intensive software rendered at the moment? - motion blur - improved smoke and clouds - realistic reflections - sunbeams - adaptives depth of field - refraction of light - alpha-2-coverage (used to render vegetation) - soft particles (explosions/smoke) - rain effects - variance shadow map (realistic shadows) - many more And the complete API is said to be recoded to improve usability and performance. Sounds to me like ArmA2 could benefit from it... There are also some impressive picture comparisons out there: DX9: DX10: DX9: DX10: Are you sure directx10 could not improve the performance of ArmA2? Regards, Flo

Hi BIS, I wonder if there is any developement roadmap about ArmA2. Even if the version number is 1.02 at the moment it feels more like a 0.02. It would be nice to know what BIS is planning to release with the next patches and which features are planned in the future. - 64bit client version? - 64bit Linux server? - DirectX10? - Crash to desktop fix? - Performance boost? - Better RAM usage? Would be nice to know what's planned. Regards, Flo

Ok I understand that but this way the UAV is not usable imho. And I am not sure why I can only target the 1st target and non of the following targets the pilot gets insight. The Pilot is targeting like crazy but no hellfire lock appears and every hellfire fired does not hit.

This works once for my 1st target but not for any other target I try to lock. The pilot tells me "Target Tank" and this "broken" red circle appears at the target but no green circle or square. And I fly directly in the direction of the new target... tried it for three hours now...

Yes that's what happend to me too :(

happened to me too and I recognized his dead after finishing the LAST object... 4,5 hours gameplay with lots of fun ended in 100% frustration... Do I really want to play it again. Not to mention I restarted the mission several times because of bugs: - The Lady was not in front of the church - After reloading a saved game the mission ends after some seconds telling me I did a murder??? - Starforce21 was no more available - The UAV was gone and I never used it. OMG - Bohemia - what have you done to me :) ---------- Post added at 06:57 PM ---------- Previous post was at 06:54 PM ---------- No it was a heart attack I guess - happend to "my" Cpt. Shaftoe too - so I ended Harvest Red at this point... too much frustration for an old man like me :) Sorry Bohemia - if I would have enough motivation I would give the game to my lawyer to get my money back.
