Ok, so in pursuit of locking down performance issues and other issues I’ve noticed following (in Unreal 4.5.1).
– Exponential Heightfog disappears when PIE (play in editor) or when you cook game when used in conjunction with world composition. Fog has been placed in persistent level, deleted and re-added for testing purposed.
– In a windowed mode (this could be graphics card dependant) with a 780m I loose on average 20FPS or increase 5 - 10 ms latency. I noticed this from a standalone build, it was odd that entering full screen Alt+P and setting r.SetRes 1920x1080 increased performance drastically.
– Dependant on screen size, pawn / character will drop through floor
– In editor dependant on screen size, camera will appear closer or further away from actor / character
– texture scalability settings (from engine scalability) will cause tile edges to break apart when using world composition.
That’s all I have for today :)…
