This doesn't happen to me on my 144Hz Dell S2716DG. Forza Horizon 4 does default to 72FPS though. Make sure your friend has gone into the graphics options and changed it to 144FPS.Can someone tell me does this game run with an unkounlo frame rate? Or is it running (if you have gsync) with a frame rate which is a multiple of your max for?
I have a mate with a 144hz gsync panel who is telling me that his fps is locked to 72.
He says he sees the same behaviour in Wolfenstein 2.
I've told him these games should run with an unlocked fps. (Definitely Wolfenstein 2)
