What's wrong with my graphics card clock speed in FSX?

I've been flying a lot but I never fully understood how to setup my fsx.cfg, or any other config file, so I never altered them.

Recently my frame rates suddenly went into the high 0's (7-9)(lol) and my driver crashes a lot, so I wonder if there is anything wrong with my config, or maybe something else?

I have not overclocked my Graphic card or my cpu, because I'm lazy and don't want to do the stability test XD so that shouldn't be a problem. The computer also worked fine for a while, so it isn't my computer's fault.

Its also not any addon's fault because I found out that my graphics card's clock speed is only 405 instead of 1300 and barely no memory clock speed even though its at 99% usage see screenshot below

Also you might notice that before the memory dipped to 163 MHz (or something similarly messed up) it's @ about 430 MHz and at that time my frame rates are about 22 - 24 (which is still bad but my memory usually run at 2000 MHz or so)

I don't get why the clock speeds dips so low so VETERANS PLEASE HELP!

Thank You!

Updated graphic card drivers lately?

Open Nvidia Control Panel and under `Manage 3d Settings` set Global Settings - Power Management Mode - Prefer Maximum Performance then re-run the test...
