Using steam in-home streaming to stream fortnite

[POTATO-2187]

Has anybody been able to use stream streaming to stream fortnite recently? It used to work but some updates made it stop working properly. If I select the epic launcher as the non-steam game and then manually launch the game it only runs in 30fps.

I am having the exact same problem, I got the picture to display with fewer compression artifacts but the framerate while streaming is still terrible. From other posts, i think it may have to do with the encoding and whether the encoding used by fortnite matches the encoding used by the stream, but i dont see any way to change the encoding in fortnite.

I have the same problem.
Game can be streamed in two ways:

1. "game polled d3d11 nv12 + amf h264" excellent, 60 fps
2. "desktop dwm nv12 + amf h264" bad, <30 fps, random fps

first happens when game uses battleye, and second with easyAntiCheat.

It looks like that it is random which one of them will be selected. Maybe odd days in month one, and even other. Or some number of starts one, and equal other, or some other parameter and rule.
There should be a way to force battleye.


there are some commandLine options:
to start battleye: -fromfl=be -noeac
to start eac: -fromfl=eac -nobe

maybe they could be useful.

looks like that on even days (e.g. 2022.01.08 gmt +0?), game is started as battlEye,
and on odd as eac (e.g. 2022.01.09).
Needs to be rechecked as well as precise limiting, switching, changing time gmt +0 00:00h?

Hmmm 2022-01-14 18:32 CST and it launched with EAC. Just making a log to see if it holds per day.

[Marko]

thank you for logging.




for me:

eac - odd days.
battleye - even days.

threshold. gmt +0 00:00h. (not cst)



there is also some other, unmentioned tweak when starting fortnite. when streaming, if epicLauncher is selected, almost nothing is visible.

i then use anyDesk to see remote desktop and press fortnite icon on epicLauncher.

it is also possible that in steamRemote (even if not seeing 90% of epicLauncher contents) you press minimize button on epicLauncher. whole desktop would be shown then, at which point it is possible to press fortnite icon (contains epicLaunch uri, not file path) or start it from start menu.

Somebody has repaired this inability. i do not know when from, but when i started fortnite on 2022.02.01. it was eac and d3d11. the same happened on 2022.02.03.
