I have an AOC Q27G3XMN and while I do get reduced motion blur from this, I also experience very bad color banding/shifting. Messing with some of the values in the script config makes it slightly better, and changing the overdrive setting on the monitor seems to affect it as well, but there is still pretty strong banding no matter what strength it's on. I tested on my phone (Pixel 8) and it works very well there without any banding or color weirdness, so I guess it's just something about this particular monitor that doesn't work well with this method.
