Hi, I'm experiencing a very weird issue with my preowned GTX Titan X Pascal. It's showing symptoms of having a bottleneck, since in games like BF1 and other more demanding games, the framerate seems to remain around the same value no matter the settings (varies from game to game). If, for example, I turn the settings up to ultra in BF1, I'll get around 95 to 99 percent usage, but if i turn it all the way down (and 50% resolution scaling) I get the same framerate but just much lower GPU usage.
I know this is a sign of a bottleneck, but I can't for the life of me figure out where it would be. My specs are:
GPU: GTX Titan X (Pascal)
CPU: Ryzen 7 3700X
RAM: 16gb of DDR4 at 3200MHz
PSU: 750w
In most games, the CPU usage doesn't really ever go above 50% (though certain cores do sometimes hop up to the 90'ies, but only ever for a few moments)
At first I thought it might've been the CPU thermal throttling since it was running really hot, even when idling, but I've since gotten a Noctua NH-D15 and my temps are wonderfully cool, whilst the issue persists.
I've tried so many things besides looking for the potential bottleneck, like reinstalling drivers, rolling back drivers, re-seating the GPU, reinstalling windows, turned G-Sync off, and nothing has worked.
I also think it's worth noting that in a game like Minecraft, I'll get between 60-30fps with GPU utilization at 15% or less.
Thank you in advance for any help you might give me
EDIT: Forgot to mention that I doubt the GPU is thermal throttling, since it's showing this behavior no matter the temperature. I get max 84 degrees when using it but that's only when the GPU is actually being fully used.
