intel arc a770 16gb bifrost vram leak dayz

[Jonnybads]

Whenever I got to vorkuta on the Namalsk map I get really bad stutters and after about 4 hours my vram usage has climbed to around 14 gb of vram usage and is still climbing and the game becomes almost unplayable. Dayz is the only game i have the issues on. I've searched everything I can think of to find info on but it seems like I'm the only one with the issue or plays dayz with an arc card so I'm not actually sure if its the arc card. I am currently running driver .4887 and was installed with ddu in safe mode. this problem also exist5ed in 4885 and 4826

specs:

cpu- amd 5800x3d

mobo- asus TUF x570 

ram- corsair 32gb LPX 3600 

PSU- AGK 850w 80+ gold certified

windows 11 home 22h2

I play on the DayOne community servers which are lightly modded. 

I didnt have this issue on my rx 6800 16gb with the same system specs.

I've tried everything I could to figure out the problem so this is the last resort. everything else i play runs fantasic

forgot to add this is on 1440p. and is installed on a m.2 nvme ssd

Hello Jonnybads,

Thank you for posting on the Intel communities. As a gamer I understand how frustrating is to have memory leak issues with the Intel® Arc™ A770 Graphics while playing Dayz, I will be glad to help you.  

To understand the situation in a better way, please answer the following questions: 

• What app did you use to measure the memory leak?
• Take screenshots of the game settings in case we need them to replicate the issue.
• To know your system and hardware information, run and attach the report for the following tool Intel® System Support Utility for Windows (SSU), you can find the steps on the link How to get the Intel® System Support Utility Logs on Windows.

ill get it all posted tonight, will make sure to go on a 4 hour session to make sure to provide a good report. I 've used msi after burner to measure the vram usage, the uninstalled it completly incase that was causing issues as i really only wanted to it to monitor fps. then monitored it via task manager and again with arc control. same results. 

for the settings if you need to recreate the issue, first set overall to high as this controls draw distance then make changes to the other settings. Just dayz things I guess lol. i would also recommending running to a big city to see how bad it stutters. runs like a charm outside of bigger cities but its a slide show in the cities. It may not be a gpu issue but my knowledge kinda ends with everything I've tried.

Hello Jonnybads,

Thank you for your time.

We still working on the investigation, but now I have a couple of questions:

• You mentioned you play on the DayOne community servers which are lightly modded. Is the issue still present if you play the base game no mods or another server with no mods?
• What's the game store where you bought the game?

The map I play isnt an official map. i have played on official servers on livonia map so completly unmodded and htough i didnt have it in me to play the map for 4 hours due to not knowing the map but when i made it to a decent size city/town the terrible stuttering still existed but outside of the cities/towns i would stay around the 350ish fps mark running the same settings.

I bought the game on steam. thats the only place i think you can get it for pc I believe

Ty very much, Im not used to getting actual support from a company so thank you very much. I do love this card and it runs just good for the games I play atleast except dayz  ofcourse, but its also dayz so sometimes its expected lol.

Hello Jonnybads,

Thank you for your time, for us it is a pleasure to help you.

We continue to work on your case and in order to continue we would like to clarify a couple of things before proceeding with our research:

• I understand you did not play the same amount of time in the official Day Z map, however, we would like to know if you observed the same behavior with the VRAM used climbing progressively or if it just had performance issues. Furthermore, I understand we insist on this, however, it is important to make sure it is also present in the base game, and it is also important to proceed with our testing.

We appreciate your time and help so far.

Yes the vram did climb over the 50 minutes or so I played on official. it started at around 3000 mb of usage then climbed to about 7000 mb of usage over the 50 minutes I had played on the official map

Hello Jonnybads,

One more time will continue with the investigation before proceeding with the testing, I will be back with more information as soon as possible.
