I pinpointed what is causing this!
The slowdown is caused by my movies!!
My movies are all WMV, and they are located in " Content/Movies" inside my content browser .I then make a media texture and from there i create a texture material that i either use inside a UMG or as a material for a actor.
The (details) source for the movie is the default “File or URL” and the stream mode is from “URL”. Each of my movies original location is located inside my dropbox folder.For some strange reason when i created my streaming levels this started to create the slowdown! If i go to my dropbox and change the folder name (that contains all my videos) to something else and unreal cannot find the path for them everything goes back to normal. WTF???
The reason i told you earlier that when i first opened my game with the new graphics card everything was ok , it was because i hadn’t installed dropbox yet and i had accidentally found the cure for it.Before i went to bed i left it open to download everything and in the morning when unreal found my videos she started behaving badly again.
You can see in my second picture that the video is missing. My CPU is happy again!
Now i sometimes have 120fps both in the editor and in my preview and sometimes i have about 75 (as seen in the picture). It is a HUGE improvement but the question is why on earth would my videos file path cause something like this when i started using stream levels? Why my GPU usage is still so low and why do i have seams in my tiles?
Questions , questions questions…
