Gpu usage oscillating on p3d v5.3

[Klas]

So i recent bought a rx 580 with 8gb vram, and when i installed p3d with all the addons that i used, i saw that the gpu usage was oscillating from 100% to 70% then 10% and then back to 65%, and this is causing sttutering on the simulator, anybody nows what It can be causing that?

Hello Klas ,

If you just load the P3D default flight (F-35 at KRND) without Add-ons running is that ok?

For calculating AffinityMask, use this calculator:

After making any changes, reboot and see how it works now.

PS: The GPU usage will fluctuate, depending on the load the CPU puts on it.

Hello again, so i did all the things that you said to me and i fixed the oscillation, but the fps now is stuttering a lot, it goes 40 then 20 then 32 for the entire flight

That will also happen, depending on the combination of the aircraft you fly and the terrain you fly over, all linked to the horsepower of your computer.
