Fps decreases or spikes because of GPU issues when usage is limited to 30% to 70%.
Hi, I've noticed my FPS fluctuating a lot in all games lately. It seems my graphics card isn't being utilized fully. I have a GTX 1070 and an i7 6700k processor. I'm unsure if the issue lies with my power supply, which is rated at 430 bronze watts, or if it's related to the fact that a 1070 typically needs around 500 watts. In Battlefield 5, my GPU is only using about 30% while my CPU is consuming around 80%. I know BF5 is quite demanding on the CPU, but I'm wondering if it should still be getting the most from my GPU. I'm not sure if this is the cause of the FPS spikes, but seeing videos from others with similar setups that maintain more stable FPS makes me think maybe their GPUs are being used more efficiently. Anyone have any suggestions or solutions?
It's likely related to your power supply.
A good guideline is to consider your CPU's power use—about 95W before overclocking—and your GPU's 150W under full load. Add them together and double the result (this gives the 500W figure).
Calculating this way shows you need around 490W to run your system.
This accounts for more than just the CPU and GPU; it includes SSDs, memory controllers, PCI-E lanes, actual memory, and other components.
NVIDIA also reports its power use differently—just 150W for the GPU core, not the entire board's draw. The GPU die is only part of the overall system.
