Winapps running cpu @ ~25%. Fixed by changing performance options

Hi, I was struggling with high cpu load while the vm was idle, with no programs running. It often maxed out the vm cpu usage, and had the computer's cpu sitting around 25%.

I found this blog: https://hex.ro/wp/blog/kvm-qemu-high-cpu-load-but-low-cpu-usage/
which suggested a solution by changing the performance options from the default 'hypervisor default', to setting cache mode to 'none', and IO mode to 'native' (screenshot attached)
. This seems to have brought the idle cpu usage down to 1-3%.
I don't really know what these options are doing, so I don't know if there's a downside to this.

Is this a sensible change?
And if so, maybe it could be added to the setup instructions.

Thanks
