FPS drop while in game play

I just purchased a Rx 7900 XTX GPU a couple months ago.  In the last couple of weeks, I have noticed an FPS drop while in gameplay of 5 to 7 seconds then it will stop.  It will return again at random times during the session.  I am leaning more towards a cooling issue as the weather is warming and my home is kept around 75~ 77F during the summer months. I  I did not see this when I first purchased the GPU back when the weather was cooler.  I have adjusted the fan curves on the CPU and GPU and not much has changed.  

Does this truly sound like a cooling problem? Or could it be a new driver ( I did notice it after the last driver update).  I haven't put up an overlay of system parameters yet.  I should do that to monitor temps.

My system is as follows:

AMD Ryzen 9 5950X CPU (Gigabyte Waterforce 3-fan liquid-cooled vented out top of case), AMD 7900XTX GPU, Gigabyte Aorus Elite Motherboard, 2 TB Samsung EVO 970 Plus NVMe SSD, 1TB Samsung EVO 970 NVMe SSD, 32GB RAM, 1000W PSU.

Running DCS World at 4K resolution with high setting parameters with TrackIR only on 40" 4K TV.  Notice FPS drop when at low altitude when ground features are more defined.

Need to get some bases covered first to make sure your base is solid to trouble shoot from

Is the firmware on your SSD's up to date? 

Is your motherboard's BIOS up to date?

Is your Windows install up to date?

Do you have the latest AM4 chipset drivers installed from

Did you run the program called "DDU" to remove all past present GPU drivers of whatever video cards you have ran on this install of Windows prior to installing your 7900XTX?

What power supply make/model/age are you running?

Are  you running separate power cables from your PSU to each power input on your GPU?

Have you checked your CPU/GPU temps while your system is under load? If so, what are they?

What speed is your RAM actually running at?
