In situations like this the bottleneck (in this case not a MAJOR one) will occur as the CPU is far weaker than the GPU in gaming terms.
This means you want to remove workload fro mthe CPU and increase the load on the GPU.
You can achieve this (weirdly) turning up the dials on the gfx settings in many cases. It sounds counter intuitive, however this will prioritize the GPU and make sure it is utilized more than the CPU.
I don't think theqre will be a problem here.
