I've got both a GTX 1080 and a 4070 Super, and I thought there would be a huge difference in performance based on their specs, but I'm running into some odd behavior with my 4070. I've updated drivers, and my power supply and CPU are sufficient, but when I play games, it doesn't seem to perform as expected compared to the 1080. For example, in one game, the 1080 stays around 20-35% GPU usage on max settings, showing better performance and lower heat, while the 4070 ramps up to 50% in the menu and overheats when idle. I've also noticed strange shifts in usage percentages depending on the game settings and situations. I've tried adjusting the NVIDIA control panel settings, including Vsync, but haven't seen any improvements. I'm just trying to understand if there's something wrong with the 4070 or if I'm just not measuring the usage correctly. Any insight would be appreciated!

It sounds like you might be misinterpreting how GPU usage works, especially based on the tools you're using to measure it. If you're checking the Task Manager, it's known to be unreliable for measuring GPU usage accurately. The 4070 uses a different architecture compared to the 1080, which could explain the variability you're seeing. Try to test both GPUs under full load during intensive gaming and see how they actually compare when pushed to their limits.
