RTX 4070 performs at the same speed as GTX 1080
The difference in performance comes from how the system handles settings and resource allocation. Even with the same CPU, the weaker GPU may not utilize its full potential under certain configurations, leading to lower frame rates compared to your setup. The numbers you saw likely reflect the actual usage and optimization.
It seems the current setup isn't improving much, so the best option is to upgrade the CPU. That would be the only way to make a noticeable difference, at least to demonstrate it.
