I have a problem when playing games in my Lenovo Z70-80 laptop (8 GB RAM, intel i7, two GPUs).
The game plays perfectly fine when the laptop runs on battery (at around 60 FPS constantly), but when I connect the charger the game starts lagging. The lagging follows a repetitive pattern of running at 80-90 FPS and then presenting a lag spike which drops it at 5-10 FPS (!) and is repeating over a fixed period of 10-20 seconds.
When checking the performance in task manager, both the CPU and GPUs show spikes of reaching the top performance and the dropping again, and not constant performance.
I have already tried running the Laptop without battery, and changed the charger, but without effect.
Any advice would be most welcomed.
