OMG...how many time it's pass.

I'm back today to play this games and i see it's very most version it's been released.....

At right now i have pick the stable 1.7.4...... i have extracted and i have test whit this games:
"Crash Team Racing"

The video emulation it's good right now...
My pc it's an I3-6098P and my graphic card it's now a Ati r7-360 whit latest driver.
At this time i need some help..... how it's better to set ?
Vulkan ? OpenGL ? DirectX ?

Apparently default it's Vulkan........

During the gameplay the audio choppy.......... not ever but it's very disturbable.
On setting i see the latency it's setted to "Medium" it's good ?

How you can suggest to obtain a much better emulation ?
