I'm having a frustrating problem with my gaming setup. While playing certain games, I've noticed that my GPU usage suddenly drops to around 60-70%, which really tanks my FPS and overall performance. I've run diagnostics on my CPU, which is less than a year old, and everything looks fine there. Interestingly, this issue doesn't appear when I run benchmarks. An Afterburner OC scan sent me a message saying "Dominant Limiter: Voltage, Results unstable."
I have a 950W power supply, so I'm pretty sure that's not the issue. Initially, I was using a Gigabyte RTX 4070 Super, but after some testing, I thought it might be a GPU malfunction, so I switched to an ASUS RTX 4070 Ti Super—but I'm still facing the same problem. My IT friends and I are stumped, so I'm turning to the community for help!

Thanks for the tips, everyone! I’ll definitely look into the power management settings and monitor my CPU usage while gaming. It's just odd since benchmarks run perfectly. I appreciate the suggestions!
I’m with you on this; it does sound like something deeper. Since you’ve checked your CPU, consider other factors like your power management settings in Windows. Make sure you're using the 'High Performance' plan. Sometimes background applications can also interfere with gaming performance. Try checking for anything that might be utilizing resources while you play!
It sounds like you could be experiencing a CPU bottleneck, especially if your GPU performs well during benchmarks. Even if diagnostics show no issues, your CPU's performance can vary under game loads. Have you tried monitoring CPU usage during gameplay to see if it spikes? It might be worth investigating further to see if it's throttling or something unusual.
