RTX 5070 performing WORSE than RTX 4060 in Cyberpunk 2077. Need help.

Hi everyone. I just upgraded from an RTX 4060 to an RTX 5070, but the performance is terrible and I’m confused. My Setup: CPU: Ryzen 5 5600 GPU: NVIDIA RTX 5070 Mobo: ASUS Prime B450-Plus (PCIe 3.0) RAM: 32GB DDR4 @ 3200MHz PSU: 800W OS: Arch Linux (Proton GE) & Windows 10 (Dual Boot) The Problem: I’m hitting a massive performance wall in Night City: 1440p (2K) Ultra: 45-50 FPS. 720p Low: 55-70 FPS. CPU usage is constant 90-100%, while GPU usage stays around 50%. The weird part: On my old RTX 4060, playing at 1080p (High/Ultra, DLSS Quality), the game was much smoother and I had higher and more stable FPS. With this significantly more powerful card, the experience feels like a downgrade. I’ve tested this on both Windows 10 and Arch Linux (Proton GE) — the results are identical, so it's not an OS-specific issue. Questions: Why is the 5070 giving me fewer frames than the 4060 with the same CPU? Is the NVIDIA driver overhead on the 50-series significantly higher, killing my Ryzen 5600? How much is the PCIe 3.0 bandwidth on my B450 board choking the 5070 compared to how it handled the 4060? Is there any way to optimize this without being told to "just buy a new CPU"? Any technical insight is appreciated. Thanks!
