Hey!
So I am trying to develop an immersive AVP Game. After optimizing a lot for VR gaming the main problem I noticed is that the fps drop significantly when rotating the camera. If I move the camera along x,y,z through the world the fps stays high even when culling is activated. But when rooting the camera even with an empty level the frames drop from 120fps to like 70-80. As I need pretty high frame rates for the AVP, I guess fixed 90fps, that’s a big problem. Especially as the AVP seems to have big problems with switching frame rates. For example it seems to be better to use 45fps fixed than 50fps as the AVP expects or reuses the frames to fit 90fps. When using 50fps it seems to make weird interpolations of the pictures. 45*2=90 so it keeps the frame for 2 “frames“.
Any idea how I can maintain the high and stable frame rates when rotating the camera for example with head movement? I read it may be of how UE recalculates things that cause the frame drops.
Thanks in advance!
