Hi,
I wanted to buy FH4 because everybody seems to love it, but Forza is expensive and I’m not some hardcore gamer. So I wanted to try demo first, but ater first couple of minutes, the game made me sick. Graphical performance was absolut trash.
It should be bug or something like that, because my HW is running max like this: CPU 30%, GPU 40%, RAM 8Gb and the graphics of the game is stuttery, sometimes slown down, fps seems to by pretty bad and the in game GPU monitor does not even working, it’s not showing fps and the GPU usage percentage is stuck on 30% with some weird flickering.
Make sure your video card drivers are up to date, Might want to use DDU (Display Driver Uninstaller) to wipe out the old drivers and install the new ones. Also make sure the Frame rate ion game is not limited to something real low, the 590 should max the game out easily at 1440p, tho 4k may be a bit of a stretch, im not sure.
also make sure Windows is set to Balanced performance mode, if its already set to that, try High Performance power plan, it will keep the CPU at its max clock, which can hit the FPS if the CPU for whatever reason doesn’t want to clock up due to low load.
Disable Game mode, Sometimes that helps, sometimes it has no effect on performance. Play in full screen, this game has some sort of weird stutter feeling in windowed mode that some people have experienced including me, fullscreen smooths everything out.
Are you sure you actually changed the graphics settings in-game? They default very low and that usage definitely isn’t right, running the game at 1080p @ 144fps/hz and my 1080 TI black is at 100 percent.
