Hello,
I bought a cheap "Freestyler USB to DMX512 Interface" on Aliexpress for about 12€ hoping to have a bit of fun with my lights.
It was recognized instantly by QLC+, but I still have the issue that many people reported here in this channel.
Despite editing the configuration to an higher or lower framerate (both general or dmx) the refresh rate is steadily under 2fps. This makes any fade incredibly choppy and fast scene/chasers can barely be seen in my fixtures.

And on the box it says "Mini USB to DMX512 Interface Adapter -uDMX (HK-WDMX03C)".

The only thing that sorta fixed the issue is changing the refresh to 16Hz, but that's still too slow to have decent fades.
Any help? Should I throw it away?

I am experiencing this problem too, but only noticeable when I have a timer adjustment open with a visible tap button. if you are in virt desk with a timer disable the tap display for some BETTER results.

Get a USB RS485 adapter like this one:

Or even a genuine FT232RL adapter like this:

or this:

Oh yes - RS485 is DMX.. and DMX is RS485.. well ish. These will all work with QLC+ as USB adapters anyway, that's all you really need to know.
