I recently got an ASUS TUF 5080, and i have some weird fluctuation in performance in some of the games i`ve tried so far (MSFS 2020/24, Indiana Jones, COD BO6). Everytime the game starts running smoothly, with decent FPS and no stuttering, and after 20-30 minutes of gameplay (sometimes more but other times even less), the fps drops heavily, input lag rises significantly, and the weird part is that even tough the GPU usage is at 100% when this happens, the GPU temps drops from around 60 degrees to around 40. Sometimes it resolves itself after 2-3 minutes, and then runs smoothly again, other times the only solution is to restart the game. So i`ve installed GPUz to see if i can find anything, and first of all i`m not missing any ROPs, and then i tried to watch what happens when the stuttering begins. As you can also see in the GPU-Z sensor log i`ve attached (while in MSFS 2024), the GPU Load stays pretty much at 100% with ~15GB Vram usage, but the board power draw drops from ~300W to only ~100W, and the temps from ~60 to ~40-50 degrees. I`ve also noticed that the memory controller load is around 5% when the stuttering occurs, while is around 20% when it all runs ok (i`m not sure what percentage the memory controller load should be in normal situations).
It happens both in DLSS mode or TAA, with frame generation on or off.
Other specs are: Ryzen 9800x3d, on an ASUS Strix 870E, a Samsung 990 PRO SSD and the PSU is Corsair 1000x RM.
I also have all the drivers up to date, from the GPU, to the latest BIOS, and motherboard drivers.
Any idea or suggestion of what it might causes it?
Thank you!
