i recently got a new PC (AMD 9950X3d2, 64GB DDR5-6400 RAM, RTX 5090) and on this new system i also have these very subtle periodic microstutters every second like before. fresh system, no other software except for windows and flight sim.
it's very subtle so maybe a lot of people don't notice it and it varies in intensity. sometimes it's gone, then it comes back. basically i just use MSFS 2024 ultra settings. nothing changed from these settings.
and like before, only with black square aircraft (in this case i only tested the TBM unlike last time)
