I recommend using 720p to ensure that it's CPU-limited. In my experience, you shouldn't have to actually disable SMT, just change the game's process affinity while it's running.Sleep status is not supported on Windows where Simultaneous Multithreading(SMT) is disabled in BIOS Setup Menu.Relationship with Disabled Veteran’s Outreach Program. My board is msi x370 xpower gaming titanium with bios 1.1. Hey guys I just got finished setting my new Ryzen 1800x build and have been unable to figure out how to disable smt on this thing.
