Occasional strobe light flashing sun

[wolfgang784 13]

I have had this problem for maybe two weeks out of the month I have been playing. It does not happen in regular Arma II matches, only in DayZ.

Sometimes when I am playing, the sky will begin to flash rapidly like a strobe light. It gets brighter and brighter and it becomes harder and harder to see until the entire screen, even if I rush into a building, is completely white for a moment before it slowly goes back to normal as if I had just taken off NVGs after looking at the sun.

There is no visible trigger for this error, no pattern except that I need to be outside when it initially happens and I have not seen it happen in any of the major cities, just the forests/fields/mountains/very small villages. It just happens while walking, nothing else. Full blood, low blood, walking or running, shooting or not, talking or not, zombies in the area or not, rain or shine (not at night though).

None of my friends have ever experienced this problem and it is not too bad of an issue (not like those damn wire/tank trap errors, woo for the next update) but I would still like to find a fix for it. I will provide all the information I can think of, although since it is with DayZ only so far all of this information likely is useless.

My drivers are up to date, my BIOS is up to date, my temps are all low, memory is low (no memory leaks), and my system is not under load. I see no abnormalities in anything using speccy, cpuz, and gpuz.

Wanted to bump this thread. I have the same issue and it's only been happening for me since the last few patches.

I have the exact same issue.

I played through arma 2 mission in chernarus campaign for 3 hours without issue, i then loaded up dayz and boom it starts strobing straight away.

It is definatley dayz or the beta patch.

Trouble is I only just started running in crossfire, and the issue started as soon as i installed my new 2nd card, I have for the longest time thought it was an arma 2 and crossfire issue, but now i think beta/dayz.

when i turn crossfire off the issue stops.

i have read at least four users so far who all run crossfire and are having this issue. this needs highlighting.

i loaded up the armory with just arma 2 beta running and strobing starts. it isn't dayz it is the beta.

yeah there does seem to be some issue with the beta and crossfire. I have the same problem as well. Although when i am running fraps, the problem goes away.

Had the same problem with my crossfired 4850s (up-to-date drivers etc.) but haven't played ArmA 2 without DAYZ. Did some digging on the internet and ArmA II seems to be the problem. Found a fix that has worked perfectly for me.

Go to Documents>My Games>ArmA 2, open ArmA2OA.cfg in notepad and change HDRPrecision=whatever the number here is to either HDRPrecision=32 (which mine was defaulted at) or HDRPresicion=16 (which solved the problem for me). The post also suggested setting graphics memory to default but I didn't need to.
