When I coded my game on 4.18 UE , the packaged game starts up quite quickly. However, it became excessively slow after I migrated project from 4.13 to 4.18.
I need 4.18 Engine’s new features, so I get confused by above problem.
Something I found:
4.13 game and 4.18 game startups are both slow at first time running, but at second time 4.13 game Starts up very fast(about 5 seconds) in contrast with 4.18 game (still slow).
4.13 game second startup barely load assets from disk(there is no disk occupy at task manager) in contrast with 4.18 Game, Which still loads assets from disk and has very high occupy of disk.
I’m having the exact same issue after upgrading from 4.15 to 4.18. Similarly the old version often starts slow the first time but then speeds up, the new one remains slow.
My start up log shows
[2018.01.31-17.27.03:709][ 0]LogInit: Texture streaming: Enabled
[2018.01.31-17.27.13:424][ 0]LogUMG: Display: Widget Class Cursor_C - Loaded Fast Template
where nothing seems to happen for 10 seconds and the game is not responding in task manager.
