Question M3000 Response Time?

I'm looking to get a 4K HDR TV, and the Hisense M3000 is right up my alley. Checks all the boxes, and is very cheap too. I'm pretty much right on the brink of buying it, but something I need to know about - that I can't find any info on is the Response Time.

I'm buying this TV for gaming, and about 99% of what it'd do on it would be gaming. So, does anybody know this screen's response time? Because I can't find any information on it, and if it's too high, that would be a deal breaker for me.

How's the response time with HDR on opposed to it off? Does it have a Game Mode?

Any help is greatly appreciated.
