GPU not running at maximum frequency with X-Plane

[Scramjet333 39]

Hello gents -

 

I was flying the IXEG 733 from Britain to Vienna a while ago, when I realised that my performance suddenly degraded - from 45-50 FPS, the simulator dropped to 20. On a whim, I went to GPU-Z to check the status of my GPU, and lo and behold - the chip was running at a significantly lower clock rate than it ought to be - around 900 MHz instead of my GPU's 1300 MHz. Is this behaviour reproducible in any of your computers? Furthermore, I find it odd that the GPU-Z sensors do not report a VRAM usage value, when they usually do when running other games. See attached screenshot:

 

 

What gives?

I'm having the same issue and actually just made a post then thought I bet my GPU is set as adaptive vs max performance. I'm at work and can't try out my theory.
