They indeed do. Four cores are solid, the remaining four handle multiple threads, though that detail isn't crucial at the moment. What matters most is recording the graphs once your frame rate falls. The visuals look quite strong in that chart.
It seems mostly fine, though some cores are near 80. An i7 shouldn’t face such problems. Your GPU looks good with enough VRAM, and it’s likely your RAM is sufficient. I’d say the CPU is limiting performance. Consider easing the settings a bit more.
You're seeing stable performance with lower settings, which is great. With a Haswell i7 CPU, it's unlikely your GPU is the main bottleneck unless you're pushing very high resolutions or frame rates. It might be worth checking your GPU's power limits and thermal management, but a new CPU isn't usually necessary unless you notice significant drops under load.
