Hello,
There are several issues I experienced in Forza Horizon 4 Demo on PC.
The first problem I have is that I have a native 4K screen , and when I choose 1080P resolution and framerate cap to 30fps in the ingame menu, the framerate automatically locks to 40fps with serious frame pacing issue. In the same occasion 4K works fine and can get to a steady 60fps. This happens in both performance tests and demo game itself.
Second problem is that after I use a 4K30fps settings and start the demo, at first everything works fine with a steady 30fps with a little frame-pacing issue (which is common in any 30fps locked pc game) till the first season change (From Senna to the trophy truck). After that video session , fps cap disappeared and the framerate will go back to unlocked 35-50 fps . This issue persists till the end of whole demo.
The last problem is happened whenever I drive the car to a high speed (300kph plus), there seems to be a data streaming issue of the assets, the road disappear in the distance and do not load, driving further will eventually lead to a crash into nothing. Stop for a while or rewind the road and model will reappear. I doubt this issue has relationship with my limited 4x PCIE 3.0 bandwidth ,but I have not seen this problem in Forza horizon 3.
