Summary 08301: mario / Mario Bros. (all versions): (portaudio + WDM-KS only) Drastic slowdown during title screen and intro sequence
Description Using these settings in the ini:
pa_api "Windows WDM-KS"
pa_device none
pa_latency 0.001

Zen 3 / 5800X, slows down to 70% in the title screen, but capable of 1000%+ in game. Happens in 241 as well, not sure how far back it goes just yet. I get full speed easily with other APIs.

I do notice that if I loosen the latency or use WASAPI, unthrottled speed will be 500% in the title screen, but still slower than the 1000% I see with xaudio or dsound. It's apparent that something this driver does suboptimally feeds portaudio. Other games aren't bound by portaudio, or at least not noticeably so.

Sadly I lack portaudio in my Windows install.
if I had to guess, since it is only happening in certain part is that netlist audio may be slowing things down in your instance.

Can anyone in Windows or not using portaudio confirm these observations?

I'm acknowledging for the time being.
Hopefully this can be checked properly by someone with the proper drivers/hardware.
