Re: So.. Are the devs aware of the small stuttering/freezing lag on PS4?
I think it's a shame that you have this problem, but I find it very interesting because I also have problems with Battlefront 2 with the PS4 Pro.
Here is my post, I thought the problem would be fixed with the deactivation of HDR but it does not seem to be like this:

A question about your problem, what 4K settings are active on your PS4 Pro, 2160p-YUV420 or 2160p-RGB?
I ask, since I know in my configuration of PS4 Pro, 4K AV receiver and 4K TV, synonymous a problem in combination with HDR. Because I can only use the 2160p RGB mode when HDR is disabled. Otherwise I get on the TV synonymous green flashes of light only these are much smaller than those in your video.
But I have no problems with 2160p-YUV420 and active HDR. This works excellently for me in all other games.
