that's not bracing though. you can pull it square and hold it square like that, but you're not bracing anything. any added rigidity you get out of it is because the corners are now actually square/perpindicular or whatever. and it wouldn't stop the sides from bowing, so you're definitely not stopping any collapse.
a picture frame, maybe. not a wall.
Theoretically a taught enough and strong enough steel cable would behave like bracing under certain situations, but it won't be able to withstand any sort of displacement stress or shear stress applied to the building.
If your top beam is stable and healthy and not rotten you should make a "V"

I /I
I / I
I V I
that is your best bet.
Aw well that is really gay I did the little stick figure vuilding PrepHole formatting is Black folk. Oh well. I hope you get the picture.
here its braced by the future OSB skin tho
picture frame only cuz I could get good pic on google, unlike a coplanar view of a beam wall
how does the OP pics behavior differ compared to doing two diagonal cables with two tensioners? (if at all?)
Diagonal X bracing with cables will limit twisting out of plane more than the OPs setup, given the same tension level.
It's also more resistant to racking side to side than the V suggestion.
FWIW the V wire thing is seen in picture and mirror frames where the moldings are too small/flexible to not sag under the weight of the glass and either break, pop the corner fasteners or deform enough that the glass edge escapes on the bottom.
why exactly is that? I have hard seeing the practical difference
also what if the sables were connected rigidly in the crossover point?
The difference is that small straight vertical section where you have the tensioner. Yes fixing in the middle would be better.
You also need to consider the attachment points because this is gonna be weak as shit unless those are carefully engineered
thru bolted is not enough?
the practical difference is corner to corner bracing is making big trianlges from the parts that hold each other in place . your making the top and bottom rails press the verticals by being pulled up and down, not making triangles out of the elements
Because in the case of twisting out of plane, the turnbuckle in the OP's setup is a big swivel that helps the structure twist easier.
In the case of racking,
Tying the center of the X together can help minimize twisting out of plane, probably won't have much effect on racking.
Why not use steel or wood and brace it properly?
What reason exists to use wire rope? The stuff stretches over time BTW.
less visual clutter in an open wall structure
You'd have to use 2 separate cables
This won't do shit
Yes, that's how they do like all mass production shed doors
those still have the skin for bracing as well no?
