1080 frame rate decrease and full GPU utilization at 68°C temperature
1080 frame rate decrease and full GPU utilization at 68°C temperature
Hi,
I've experienced this issue for a while now.
When I begin a game, my GPU functions properly—stable at around 60 FPS with typical usage.
However, once the GPU temperature hits 68°C, usage jumps to 100% and the frame rate plummets to just 20-30.
CPU performance remains consistent before and after this drop.
Once this condition is met, it persists until I restart my computer.
Before, I adjusted the fan curve with MSI Afterburner to prevent reaching 68°C, but I now believe that 68°C is a normal temperature.
I’m looking for a solution here.
Specs:
GPU: 1080 Ti Aorus Xtreme Edition 11G
CPU: Intel Core i7 7700K
RAM: 32GB Corsair Vengeance @2400 MHz
M.2 SSD: Intel 660p
Gpu temperatures and usage are acceptable, but I'm more concerned about the CPU. Excessive CPU usage could lead to the graphics card being starved of frames. Could you share your CPU idle percentage, temperatures, and speed when it's close to or at 100%? Is Hyperthreading enabled?
What game are you playing?
My idle CPU temperature is around 40°C. Hyperthreading is enabled. Before the frame rate drops, the CPU usage is 25-30% with temperatures between 50-55°C. After the frame rate drops, usage falls to 15-20% and temperatures stay steady at 50-55°C. These values come from "A plague tale innocence," but the frame rate drop occurs whenever the GPU reaches about 68°C in demanding games. If I keep the GPU running cool by setting fans to maximum before it hits 60°C, I don’t see the drop, though it becomes quite noisy.
when shutting down Hyperthreading, the CPU temperature remains unchanged compared to earlier, and the CPU utilization stays around 40% before the frame rate decreases and about 25% afterward. I notice the decline occurs near 72-73°C during HT shutdown.
