Hello all,

P3D v4.5 starts up running well and then performance slowly starts to diminish to the point where it is unflyable (60fps down to 0-5 fps). This occurs no matter what settings I use; all sliders to the right or left. This is a new issue that more or less came out of nowhere. I have made no changes to the sim in the last 9 months and that includes add-ons.

Below is a graph of my GPU usage. After start-up GPU usage trends downwards and will hit 0 on occasion. Every spike up corresponds to a positive spike in performance (FPS) and every drop corresponds to a negative spike in performance. The GPU temperature remains stable at 54C.

I also included images of my CPU usage and CPU clock. Both are also unstable with the CPU clock also diminishing over time. 

I'm not a hardware expert so this may be normal activity. My question to the community is; is this normal activity for the GPU and CPU when gaming or is one or more of my hardware components failing? If the later, which one? Based on what I have read so far it's either the GPU, CPU, or hard disk (SSD).

I have done a complete uninstall/reinstall of P3D. At present time, there are no add-ons installed to the sim; everything is default. I have tried all sorts of settings and nothing stops the diminishing performance. 

System Specs:

My system is old, 7 years to be exact. However, it ran P3D with no problems until now.

i7-4790 / 4 GB GTX 970  / 16 GB RAM / Samsung Evo Series 840 x2

Any help will be much appreciated.

@jc2231, don't know if this is the answer, but did you clean the shader cache between uninstall and reinstall?
