Big Video Bug with 9800GTX+

[sleayer 10]

Hi all,

If you have the same card, can you please post you video settings, os + drivers version.

I try 3 differents os (XP, Vista, 7) and different video drivers

I try different settings and in the better situation, I was able to play 2 hours max.

Normally I always get weard color into the screen and big lag. not able to play or to stop the game... I have to use the reset button.

please share your setting !

thanks

You might want to put some more detail to help people reproduce and/or understand your problem.

Do you have a screenshot of this weird color coming into the screen ?

Where is the problem occuring ?

Is it in campaign, multiplayer or ...?

I have 2 EVGA 9800 GTX+'s, E8600@4.2Ghz, 4GB Gskill@1333

Screen Res: 1680x1050

I installed Arma2 on my Vista64 partition. Put the EVGA SLi patch on, since i was expecting to run SLi. Had most settings on HIgh except post processing. 2xAA, view distance 2600. Framerates were getting down to low-mid 20s running around in cities, 45-50 elsewhere.

Had the problem of it stuttering when i was turning around fast in a new area. So i tried disabling SLi in the nvidia control panel (the 2 cards still physically connected in the pc though), and that stuttering went away. Framerates indicated were identical, but it was 500% times smoother turning around.

Tried overclocking the graphics card (though didnt know what i was really doing). It didnt yield much in FPS increase (adding further to what most people know - fast CPU is more important for sim games) - but caused the video driver to crash after some time (time to crash varied based on how much i tried to overclock). When it did crash, the Arma2 screen would go black, i could see a big windows arrow on the screen, and i had to altTab away to kill Arma2 in task manager.

So put the speed of the graphics card back to normal.

Playing the campaign i noticed the framerate getting under 20 at times, making it quite unplayable.

Installed Windows7600 (x64) on another partition of same hard disk that Vista64 was on.

Installed another copy of Arma2 on the same hard disk that initial copy of Arma2 was on.

Installed the NVIDIA SLI patch. (not the EVGA one)

Windows 7 ran Arma2 with similar framerates, but the stuttering (i had with SLI under Vista64) returned even though SLI was off. So i turned SLi ON, things seemed a lot smoother.

Started playing the campaign again, and framerates were similar to Vista64, i.e. around low20s when action started heating up etc.

So i've dropped my settings now, all to Normal, view distance of only 1700, no post processing, 2xAA still.

Framerates are 35-42 in the busy areas now, sitting on 60 in the forests etc.

Game now looks same [ worse ? :) ] than Arma1...but at least its very smooth and playable so i'm happy for the time being.

first thanks for your help.

after a LOT of different test/error, I finally play 2 night without any bug with higher resolution.

If needed, I can try to give to you all more info. But, here is big picture:

With my 9800GTX+ (512MB)

screan resolution used : 1920*1080

Quality preference is set on very high

3d Resolution used : 1680*1050

All setting is on normal except for terrain detail (high), Anisotropic filtering (disable) and shadow detail on low

in the nvdia control panel I choose the option "game decide the setting" ... maybe it's called Application-Controlled

and one important think, I cannot use the last driver from Asus or Nvdia. I have to use the old driver in the cdrom buy with the card.

later I will try to optimize video, but actually the game is very nice and no lag.

overcloker ... don't try that with arma.. I try to overclock the cpu and the video card .. but the game don't like it. The video crash like "whopper_with_cheese" said.

my setup:

ELSA 9800GTX+ 512mb

AMD Phenom 9950

2 gb RAM 1066

vista 64 ultimate

single 250 gb SATA drive

I'm using the 186 driver version from nvidia and I really don't have any major bugs. I played around with the settings but I don't really see that much difference in quality from medium to high or very high in most settings. After a few hours of testing I ended up setting it back to default settings, I just changed the interface and 3d resolution both to 1280 x 720.

The only bug I've seen was last night on a MP game, when I moved the camera around the whole city appeared to be up in flames, but they dissapeared when I moved it again.

I get over 30 FPS on average but it also drops when in cities.

Luckily I haven't had crashes either.
