Intel ARC A750 stutters in War Thunder

AjrAlves

Hey, good morning!

 

So, my system specs are the following:

Windows 11 22H2

Intel driver Version 4148 Beta (the problem also occurs with 4146 and 4125)

REBAR ON

ARC A750 ASRock

Ryzen 5 5600 @ 4.9GHz

32GB DDR4 3200MHz 

Gigabyte B550M DS3H on BIOS F17b

2x NVMe drives (Adata Falcon and SN550)

EVGA 700W PSU

LG 24GN600

Game client: Steam

 

Well, as you can see in this older topic from me , I was having some issues with Zen 2 + ARC. 

I upgraded the CPU to a Zen 3 part, re-imaged the computer and re-installed the game and drivers and my performance improved A LOT.

 

BUT, I'm having the following problems in War Thunder:

FPS stutters when moving the screen rapdly (drops from around 150 to 70)

FPS stutters when switching camera (just like a half second stutter, very annoying)

FPS stutters randomly (seem to even out during the match, but won't go away)

V-sync and/or smooth sync won't cap my FPS to my monitor's refresh rate (144Hz)

 

In the video I recorded, I show my system, the stutters I'm having, but for some reason it didn't pick my mic's audio.

 

I think DXVK would improve things in this games, but, sadly, this game won't open with the DLLs at it's folder.

 

Here you can see my recording on YouTube , but if you wan't to see it without compression, here's the Google Drive link

Hello AjrAlves


Thank you for posting on the Intel Communities. I am sorry you are experiencing performance issues when playing War Thunder on your Intel® Arc™ A750 Graphics.


We will need to further look into this issue, and you have already provided most of the information we need, I would like to ask just for the following:


  • Create a log file with the Intel® System Support Utility and attach it. 
  • In regards, to the game not synchronizing the FPS to the monitor's refresh rate, Have you tried both Borderless Window and Fullscreen modes in the in-game settings? Does the issue happen in both?


Best Regards,


Hugo O.

Hello , i ve got bad perf with my a770 , i found this :

go into game files , edit  config.blk   with notepad

change line driver:t="auto"     to   :      driver:t="dx10"

then , save , and change the file to read only  in properties 

it run perfect for me , way  better than  dx12   

 

if you want change setting in game uncheck read only  , etc 

have fun 🙂

Hello Intel,

Has this been fixed? I am trying to make a decision to purchase ARC over nvidia currently.

I enjoy Warthunder and need a card that can handle it.

Thank you!
