Hello. There is a major problem with ARC B570 in War Thunder that makes it impossible to play. I reported it directly to Intel, but I don't know if my responses arrived by email (because Intel support doesn't respond for a really long time), so I'm writing here. This is a very serious problem on ARC B570, which crashes the entire game with DirectX12, along with the system (the system literally freezes and nothing can be done). This happens when one battle ends and another begins. I guess it's because the map and vehicle textures don't get cleared from VRAM after the battle ends, and when the next battle starts, VRAM runs out and everything crashes. This is called a VRAM leak. On DirectX11, when you force it in the game files (because for some reason it is blocked normally), the problem is different. Everything seems to work, but just rotate the camera and the fps drop drastically and do not return to their previous value. These two problems make it impossible to play War Thunder comfortably, and Gaijin (the creators of War Thunder) don't care about any problems with ARC. The only option I have left to check is to run War Thunder on Linux. In my case, Bazzite. Because then War Thunder runs on Vulkan. And Vulkan is supposedly the best API for ARC. I am asking Intel support to contact Gaijin about this issue.
