FPS drop after 15 min. ingame on laptop
Here’s a rewritten version of your text, focusing on clarity and actionable information:
“I'm experiencing significant performance issues in several games – Red Dead Redemption 2, Fallout 4, Far Cry 5, Cities Skylines, and Subnautica – running on my Lenovo ThinkPad 580E. The game initially runs smoothly at around 50fps with high GPU utilization (90-95%), but then abruptly drops to approximately 15fps accompanied by a drastic reduction in CPU usage (from 60% to 20%). My AMD Radeon RX550 GPU is maxed out during this drop, while the CPU load plummets.
I’ve exhausted numerous troubleshooting steps, including: maximizing Windows power settings, setting minimum processor state to 100%, disabling Intel Power Manager in BIOS, installing fan software for constant 100% fan speed, upgrading RAM (from 8GB to 32GB), optimizing game settings, and updating both GPU and CPU drivers.
My system specifications are:
* CPU: Intel Core i7-8550U
* GPU: AMD Radeon RX550
* RAM: 2x16 GB Crucial DDR4
* Storage: Samsung 1TB SSD
The consistent pattern suggests a hardware issue, despite the initial stable performance. I’m concerned about potential thermal throttling or instability related to my GPU during prolonged gaming sessions. I'm open to further suggestions – could it be related to specific drivers, BIOS settings beyond what I've tried, or perhaps an underlying hardware problem with the RX550 itself? Any insights into diagnosing this issue would be greatly appreciated.”
The provided text details a persistent overheating issue experienced with several Lenovo laptops – specifically the E480, E490, E580, and E590 series. When running demanding games like Subnautica and Far Cry 5, these laptops frequently reach temperatures of around 75 degrees Celsius, triggering thermal throttling to maintain performance. However, high CPU usage combined with fan and throttling limitations continues to cause temperature rises, ultimately restricting CPU usage to approximately 40% to prevent overheating. The author attempted solutions including replacing the thermal paste and using a laptop stand with an integrated fan, resulting in a 10-degree Celsius reduction in average temperature, which mitigated some FPS drops but did not fully resolve the issue. A lengthy discussion on Lenovo’s forums indicates that the company has abandoned efforts to provide a permanent solution for this problem.
