Full CPU consumption in Rainbow Six Siege
Full CPU consumption in Rainbow Six Siege
In Rainbow Six Siege I usually achieve around 300FPS without limits. However, when I lower the FPS cap, my CPU usage reaches maximum and the game becomes sluggish with stuttering and lagging. It seems the only solution is to cap at 144Hz even though my GPU can handle higher speeds.
Make sure you stay calm, it's perfectly okay. Return to your BIOS settings and set the clock speed to 4.2 GHz using the default voltage. The system shouldn't trigger the blue screen and everything should function normally. To reach speeds between 4.4 to 4.5 later, you might need to explore overclocking options for your CPU, which could require adjusting the voltage and possibly implementing some compensation settings. At 4.2 GHz it should be sufficient right now. If your monitor runs at 144 Hz, you won't notice any significant increase in frame rate. But if you're aiming for higher performance on a 144 Hz display, consider limiting your FPS to around 240 or less. Increasing beyond that can stress your CPU and cause higher temperatures.
I limited my FPS to 240 and the game ran smoothly, but temperatures kept rising past 80 degrees and the CPU stayed above 95%.
The image indicates your CPU continues to run at 4.5 GHz. Have you adjusted it to 4.2 GHz and turned off turbo boost?
Then it will keep increasing to 4.5 GHz, requiring higher voltage, which is currently between 1.275 and 1.305. This voltage level at 4.5 GHz can raise temperatures to the 70s to 90s. Adjust to 4.2 GHz and turn off turbo boost. Then it should stop reaching 4.5 GHz and settle at 4.2 GHz, using less power.
You’ll still manage high frame rates since dropping just 0.3 GHz means only about a 7% slowdown. That’s roughly a 7% performance hit. If you previously reached around 300 fps at 4.5 GHz, you should still get about 279 fps at 4.2 GHz.
You can later increase your CPU to above 4.2 GHz. At the moment, prioritize reducing CPU usage and temperature to confirm this is the problem.
These are the temperatures during gameplay. They even hit 90 degrees...
