Reproduce of 3 Fps Bug [Some Infos for the DEV TEAM]

Recommended Posts

Maybe I found a good way to reproduce the Arma3 3FPS bug. Set resolution down to 1080p (in my case i usually use 1440p)Set all Settings to low. then set everything up too ultra(except textures let them be low) arma will start to go from 900mb vram(low settings) up to 1.1gbvram(ultra ones), now set the resolution up to 1440p(1920x1200) arma uses 1,2gb vram. set supersampling to 200%  arma now takes huge 2.2gb vram. finally set textures to ultra. arma now gets blackscreen ( i alwas get this one after 3 fps bug) check out logfile now:

 DX11 error : CreateTexture failed : E_OUTOFMEMORY, like everytime i crash after 3fps bug. 
 
additonal strange stuff in log:

16:46:04 Virtual memory total 4095 MiB (4294836224 B)
16:46:04 Virtual memory free 106 MiB (111935488 B)
16:46:04 Physical memory free 7690 MiB (8064290816 B)
16:46:04 Page file free 8919 MiB (9352835072 B)
16:46:04 Process working set 2993 MiB (3138584576 B)
16:46:04 Process page file used 3416 MiB (3582570496 B)

so why it is strange? cuz i'm using a gtx 1070 with 8gb vram, and even windows added another 8gb optional dedicated ram of my 16gb ram to it so it can use up to 16gb of vram, arma it self uses its max of 3gb ram if in need + pagefile. so it seems the bug is caused by an dx 11 driver level issues if i'm right?

tested this procedure on a modded mp server to reach the stress level of the game easier, but the behavour should be same like without mods because of the vram issues of 4gb max.

btw added you, so we maybe find an easy way to share the .rpt files that may help you to investigate the issue. // issue is same with and without profiling.exe

 

Additional info about my complete sys:

win 10 x64

i7 6700

gtx1070 @ 8gb gddr5 (samsung vram)

16gb ddr4 @2166

265gb ssd (pagefile used by os)

1tb hdd /pagefile used by os)

 

rpt log when crash is starting: 


 

  Reveal hidden contents

 

 

then some time everything was fine again(report of bug and bug ended 15:57:28, but then blackscreen(16:15:50) while .rpt was saying:

 

  Reveal hidden contents

 

hope this can somehow be fixed soon, because i think this still can happen in 64bit version that is developed. if devs need full report logs or other details, just give me feedback and i will do my best to help.

One thing to add maybe: i usually play at 1440p @ ultra and arma3 usually takes 3.5gb vram at start, so maybe the issue is around 4.2gb vram usage, and that can be reached very fast for me, in this case.

One sure thing, some people think that makes no difference if we have 20 + mods loaded at start if we don't use them. It's a bad idea. All modded stuff (functions/unit classes) are loaded. Furthermore, some mods are preemptive for some behaviors, especially replacing classes as radios, medikits...

The less mods, the lighter memory management, the less conflict, the less crashes.

 

Just use the mandatory mods for your scenario. Discard the other ones.
