RX 5700 XT very high VRAM usage

Hi all,

 

I just switched from a perfectly stable GTX 1070 to a RX 5700 XT Anniversary edition.

Mostly it works fine, but i noticed the amount of VRAM it uses it unreal.

 

In desktop (without any application opened) it uses 0.8GB of VRAM.

Playing COD:WWII, after a few minutes into a match it uses 8/8GB VRAM and the stutters begin to happen. According to the in-game settings the aprox. VRAM usage should be 3-4GB, not 8. I know it didn't go past 4GB VRAM with my old gtx 1070, it was hard to make it go past 5GB even. But this RX 5700 XT seems to love huge amount of VRAM.

So in other words, COD:WWII becomes unplayable during the middle of the match.

 

HW Specs:

Crosshair VI Hero (latest BIOS Version 7601, X370 chipset, here I didn't get what's up with the chipset drivers on ASUS website, if I launch the installer for the chipset it just looks like installing Radeon Adrenalin Software again...!?)

Corsair Vengeance 32 GB RAM @ 3200MHz (4x8)

R7 1700 @ 3.9GHz

RX 5700 XT 50th Anniversary Edition (BIOS Version 017.001.000.042, BIOS Date 2019/06/16 22:42)

Kingston 240GB SATA SSD for OS

SAMSUNG 970 EVO 500GB M.2 SSD for COD:WWII

1080p 60hz monitor (connected via HDMI)

 

SW Specs:

W10 X64 up to date (Build 18363)

Radeon Adrenalin 2019 (19.11.3, Overlay is activated, ReLive is activated only for screenshots, recording and instant replay for 30 seconds ~ 225MB)

 

I attached a screenshot from a match end where the VRAM was full 8/8GB used. I don't think it's just a display issue in the overlay since task manager shows the same 8/8GB used and once it hits 7 to 8 GB of VRAM usage the game starts to stutter.

 

If anybody has any idea why this card uses so much VRAM for no reason, i'd be glad to know more about this issue since again, my previous GTX 1070 was never using more than 4 GB of VRAM with the same settings. Considering I only play at 1080p it is even more unreal for 5700XT to need 8GB of VRAM.
