I've got an RTX 3080 10GB from Dell's OEM line, paired with an AMD 5800X3D CPU, 32GB of G.Skill 3200 RAM, a GA-AB350-Gaming-3 motherboard, and a Seasonic 650W 80+ Gold PSU. Recently, I've been experiencing drastic performance throttling—around 20% of what I expect. In benchmarks like Unigine Heaven 4.0, I normally achieve over 100 fps on Ultra settings, but now I'm only getting 15-25 fps. Even in games like the Master Chief Collection (Halo 3), my frame rates are dropping to between 80-110 fps.
What confuses me is that my GPU shows 90-100% utilization while maintaining a temperature of about 45°C with quiet fans. This performance drop happened suddenly, and I haven't changed any hardware configurations, which makes me wonder if it's a software or hardware issue.
I've already tried a bunch of troubleshooting steps: using DisplayPort from the GPU, rolling back and updating Nvidia drivers, uninstalling MSI Afterburner to see if it's causing any conflicts, and updating my AMD chipset drivers and motherboard BIOS.
I just want to know if anyone has tips on what could be causing this issue or what else I could try.
By the way, I solved the issue after another restart. I suspect there was some lingering setting from Afterburner since my performance went back to normal, getting 700+ fps in MCC again!

Your GPU hitting full usage while being at a low temperature is actually a good sign. It shouldn't be a problem as long as the system is stable. If your fans are silent and the card is still efficient at 45°C, then it’s likely performing well. That said, if you’re seeing such low frame rates, it could be something else like a background process hogging resources or a weird driver issue. Keep an eye on your GPU’s power and clock speeds; they might be throttling for an unknown reason.
Agreed, and don't forget to check your GPU metrics when you're gaming to see if it's truly running at expected speeds. Sometimes software configurations can cause odd lanes to open.
Did you change any monitors or resolutions recently? Sometimes a new setup can lead to resolution mismatches that impact performance unexpectedly. It could cause the GPU to behave differently, even if not immediately obvious.
Exactly! Different resolutions or refresh rates can drive the GPU to work harder or behave oddly. Just hope it’s an easy fix.
Also, what speeds are you seeing on the card when this performance dip occurs? Adjusting the voltages could actually stabilize things if that's where the issue stems from.
Good point! If you're seeing low speeds, it could certainly indicate that it's not getting enough power. Those settings might need a tweak.
Make sure your GPU is actually hitting its full clock and memory speeds when you're gaming. If it’s underperforming, consider tweaking the voltage or power limits in your settings. It could help get performance back.
Yeah, those low temperatures are surprising but not necessarily a red flag. If it does throttle, it could be due to the clock speeds dropping unexpectedly. Just make sure nothing's interfering with your system.
