60FPS cap when launching via Steam

For whatever reason, when launching the game through Steam, the frames are capped at 60. I disabled Steam overlay but that didn’t change anything. When starting the game through the Gaijin launcher, there’s no FPS cap and I comfortably reach 150 FPS. I read that EAC might be a factor, so I ran the game through Gaijin launcher with EAC on and off, and both instances worked fine with no FPS cap.

I’m running the latest updates for almost everything on my PC: Windows 11, AMD GPU drivers, BIOS, chipset. My monitor is set to 144Hz in windows options, I’ve disabled any FPS cap and Vsync options in the AMD software and disabled Vsync in game. Even with Vsync enabled, however, it’s still capped at 60fps. I’ve set my monitor to 60Hz and then back to 144Hz. I’ve restarted my system numerous times. There are no launch parameters set in Steam, and this only happens with War Thunder.

Any ideas what might cause this and how to fix it? I
