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.
