Be interesting to know what models of PS4 PRO you all have. I have three new 7216b model which has a faster internal hard drive. I’ve not experienced any significant frame drops so far. I have an external 1tb HD too so may copy the game over to that and see if there’s any difference. Just as a test that may help some of you.
Make sure super sampling is turned off and at the time of playing (unbeknownst to me) my boost mode was turned off. I will try later with it on and see if there’s any difference. Will also try with it set to 1080p in the PS4 menu settings as opposed to automatic. There are lots of variables here in the game’s current state it seems. I’ve had no input lag with wheel either btw.
Bottom line is, a locked 30fps needs to be their target in future patches.
mine too is a 7216b which i bought a couple of months ago but i changed out the HDD for a SSD.
