FPS drop after 5-10 mins play, suggested fixes do not work.
New, WishlistPublic


I am starting the game with no issue, loads up and getting very good FPS, up to 150 at times, occasionally dropping to just under 60.
As I play this figure drops and drops until I get an unplayable game(video evidence).
I have tried....
Launch parameters clearing.
Deleting My Docs DayZ folder.
Deleting local content and reinstalling.
Deleting local content and searching for anything related to DayZ, deleting that also(very reluctantly being a lefty it takes a while to remap keys again).
Updating Graphics drivers (clean install)
SLI on, off and on with nvidia inspector tweaks.
Changing in game settings including max vram at auto/2048 and many permutation of the whole video settings from max quality to min.
It feels like the memory is full but that is not backed up with any data or observations (refuse to use rivatuner server stats with afterburer to get the in game overlay, horrible piece of software)


Legacy ID
Steps To Reproduce

It will happen every time I start game after 5-10 mins of play, regardless of being in a city or open field. All "fixes" have resulted in no change to this behaviour.

Additional Information

Core i5-3570K@4.6 Phase change cooling so heat not an issue(also tried without OC at 3.4).
Z77 mobo
8 gig ram (2x4)
GTX 970 X 2

Video while happening.....

Sorry about the adverts, not sure how to rip the vid from twitch.

I wondered if it was an SLI issue, so have just tried taking out one card.
Still the same.

I have another pc with 2xGTX680 where I stay when working, will see if the problem is on that sys too but not there until tomorrow night.

Try -malloc=system -maxMem=2047 (none other, apart from maybe -skipIntro) and make sure your virtual memory is about the same size as your total ram. Did the trick for me.

Thanks for trying to help but that made little to no difference for me. Feels like it might be very slightly better but still totally unplayable.

Also noted exiting server and joining again or another server does not reset, only a complete game close and restart will get it going again for 10 mins ish.

Bugs still appear for me after 1 minute of gameplay or even when i log in can't even play.

Still no luck for me, have gone over all the potential fixes again just in case.
Only had one crash and that was on exiting the game from main menu, same mem error as the rest.

Tonight I tried on the other pc with gtx680's in, no FPS troubles but am getting the crash to desktop with the memory read error.

I dont know if this will be of any help since you re-installed. but I have had launch options get stuck somehow before . For instance in the experimental branch when the -nosplash option caused the game not to load, I actually had to put the option in first then load the game and take it out again to get it totally removed.

As you say it's doubtfull but I will try anything. Currently managing to play for short spells and just log out when it gets choppy, restart game and play again for a short time.

Actually the one thing I didn't try was a complete deletion of steam and start fresh.

I might have got it working. I played for 2 hours with no fps probs, as a matter of fact they were way higher than ever (45-50fps in elektro).

I had previously tried the temp fix suggested by Hicks or setting page file to 12000Mb but it did nothing. Today after playing around all day with graphics card and cpu settings, uninstalling drivers, reinstalling etc etc, i was ready to give up when I got a crash (BSOD) after big fps stopage.
On rebbot i took out the 12000Mb page file and let windows do it again, no changes again so went back in and changed min PF to 12201Mb as was suggested by the OS, which I had done before but this time I set the max to double that 24402Mb.
Reboot, check graphics for clock speed and SLI enable, apply the tweaks to force SLI in DayZ. Load game and all seems well, infact better than it's every been.
Not saying it will work for everyone or anyone else as other peoples fixes didn't work for me so it is prob very system specific as to what works.
Maybe it will help find the sweet spot on your system though.

In game it never uses all that PF or indeed all the ram but I did notice it climbs and climbs to the point the game becomes unplayable, with the larger PF max it actually used less PF and seemed to stop increasing in size before it gets to the critical size where the fps drops to 1's and 2's

Hope that helps someone.
