Turning off motion blur on my computer dropped batch count by a factor of 3 to 6 and increased the FPS by a lot. I tried turning it on and off with the demo paused. One time I was around 23k batches with motion blur off and 120k with motion blur on. this is while paused so the numbers didn't change as I flicked between motion blur on and off.
With high batch count my CPU usage for this demo was around 24%, and GPU usage around 20%. With low batch count my CPU usage was around 70%, and GPU usage 99%.
can you post that configuration?
Except "300% increase" comparison points have no meaning. You could get that on oxide with DX with optimization.
Seems a lot of complaints could be fixed by more LOD distances, and better ship models and textures. That has nothing to do with the engine, just what the artists created for the demo.
Just wondering why you stick to the arbitrary number "300", surely, had it been directx optimized it could easily be 700% right? Or are you just making up numbers.
So .. making up numbers .

LOD is breaking this engine and a pointless exercise.
About as relevant.
So you don't want to just reduce the LOD you want to not render the objects if they are a certain distance away? Otherwise you still have a huge batch count and are massively CPU bound.
Look at my OP. Far objects appear as identically indistinguishable dots yet it appears that the CPU needs to make a ton of draw calls which the gpu just mushes through and produces a dot (obviously not held back by the gpu).
it's not the best looking demo, that's for sure
seriously I've seen Winamp Visualisations looking better than that
I suppose the only way to appreciate is to know the tech behind,
but that defeats the whole purpose of Demo as in, you know...Tech DEMONSTRATION,
as opposed to reading and appreciating a good (programming) book.

And i can assure you, when you go watch Gravity in the cinema, every unit on the screen dont have its own AI and is not customizable of you as a viewer - but you can try, and btw its not Sandra Bullock i mean
you really think there is 5k objects with its own AI on-screen?
man...there is no 5k unique dots there; even if we include little pew-pew lasers, debris and whatnot
I mean wth... are they calculating gravitational field effect on lasers?
Here let me do it for them real quick right now: It's > ZERO, but < 1 pixel, so it's ZERO lol
I would suggest you look at the batch count on a paused frame and turn Temporal AA(motion blur) on and off. You will see why frame rates drop so much, it's not the LOD
I did look at your first post, it just looks like you don't know what you are talking about.
That was 3 years ago, DX11MT performance is much better since driver stack 310+.
And are you a programmer? Because just yesterday repi stated that it's "fundamentally broken".
If they are doing motion blur on a bunch of dots as in the first two pictures then its an lod issue as well.
I don't know about gravity but for the rest they are, and they will be calculating AI for everything not just what is on screen.
no it isn't, the LOD is fine it's the batch count that is causing the problem. It's rendering that LOD in a plenty short time, it's the large batch count causing the problem. Decreasing the LOD of the object won't change that.
Or I guess I should say LOD doesn't matter in a situation like that, you can't tell if LOD is going to be a problem because it is so CPU.
Why do you need so many draw calls when all you see is a dot (in the case of RTS)?
