CPU and GPU Splitting load for gaming?

[ya.weird]

 

Hey so since 3 days I’ve changed the voltage of my RX570 8GB and everything is running smoothely. No problems at all or anything. Before, I ran it on a little bit lower voltages but realized the clockrates sometimes drop. After boosting the voltages my GPU wasn’t used 100% and some of the load when gaming went on the cpu.
 

Im using an RX570 + ryzen 5 1600 + MSI afterburner for Overclocking and monitoring and amd Radeon software 

windows 10 Pro 64Bit 

8GB RAM 2666mhz

Asrock b450m hdv Motherboard 

450+ Bronze be quiet psu

i built the rig June last year 

 

 

Weirdly some games like gta or sea of thieves run smoother now. The GPU is around 10degrees c cooler but the CPU 10 degrees warmer. (70-75 and 55-68)

 

but games like Grounded or Minecraft suffer from the load distribution. 
 

I ran the heaven benchmark to test it again. While the benchmark runs, the gpu gets used to 100% 

I don’t know what else change when I adjusted the voltages but I’d like to only use my GPU for rendering again.

I really hope someone can help me and I already am thanking you for reading this
