I get periodic fps drops system wide on the Linux vulkan build too. Not in the game but for the rest of my desktop. The game runs fine for a while, even streaming it nicely with OBS... Then boom obs is 10fps along with the rest of the desktop. The only thing still running ok is the game.

I don't get this with any other game and I'm above the specs needed. What in the world is going on. Making it very frustrating to stream.
