Clearly it's not for users like you sir, it's a demo meaning demonstration, try to remember how many time ago a playable demo (with such graphics..) was released. UE 4 EPIC GAMES demos (and their launcher) is not for everyone ofc.

Actually I'll have to check it via launcher. On reddit people wrote that they had to build it via UEditor. And that would be awesome thing from authors. Because it would allow a lot of people to learn from it and create better looking graphics. This file is based on nVidia UE build as it has their libraries. (just saying) in console ` you can use: stat fps stat unitgraph ...to get some basic overview on fps and frame times.

The Kite demo and that stuff was all released, I'm sure Infiltrator will be too eventually.

Visually it is pretty impressive. At least what I could see via RDP. I did use StartFPSChart and StopFPSChart which dumps csv file with frame times. While GPU utilization via RDP was only between 40~80%, I got average 59.13fps. Will rerun once I get home. But I noticed frametime spikes upon scene changes (likely due to running it from HDD instead of SSD). And there were some frame time anomalies, but I would say RDP is culprit: Frame times in ms of adjacent frames: 10.23 20.16 10.85 19.45 10.41 19.58 10.27 19.87 ... Plus at splash screen when it waits for spacebar fps is locked, So I wonder how much it is locked afterwards.

I don't think UE4 uses ASync shaders or even does much GPU compute stuff -- but I'd like to see a DX11/DX12 comparison on the Fury X if you get time/get home. (RDP is probably going to effect some performance stuff) A guy on reddit/nvidia did it on a 970 and saw about a 9% increase in performance, which I guess isn't bad for a free performance upgrade.

Damn bad. DX11 average fps 70.85 ; DX12 average fps 69.37. GPU utilization in both... I do not even know. Because @31% fan speed GPU gets to 41°C and stays there. In KF2 maxed which looks worse I get to 50~54°C. Weirdest thing is that in parts DX11 does better and DX12 does better in others. Then I checked CPU utilization too. For both DX11 and 12 it is practically same. All 4 cores utilized between 70~90%. Maybe more cores would help, but I really do not know what this DX12 implementation is supposed to achieve. http://i59.tinypic.com/27y04r4.png Btw, graph shows fps 🙂

Seems like the 980Ti gets lower performance in DX12 too. Lame. I guess we have to wait till Fable, but if this is anything to go by, the results will probably similar. Epic better step their **** up.

Wow,you get a bit worse perf. than my single 970. Maybe it needs opt. (next driver ? ).

In full screen it looks like its running at about half native res, very blurry... Looks incredible windowed though :3eyes:

Why is it always not possible to switch YouTube videos on guru3d to fullscreen? Is this some kind of advertisement so you always have to see other page content?

Whatever thing (CMS?) Hilbert uses to embed youtube videos does pretty bad job. It lack fullscreen attribute and thus no full screen option. Also this forum only annoyingly only embeds flash youtube videos which sucks big time. I don't have flash installed any more.

I used that link from keno34 and dunno looked sharp even after i pressed alt+enter to go full screen. Also dx12 ran smoother here no streaming hickups by scenes switching.. Overal it was 55-80ish fps, lowest i saw was ~38 40fps towards the end by that flying drone and them floor tiles flying around.

Here you go, FuryX: DX11 Avg 66.952 DX12 Avg 67.354 Though the DX11 frames i don't trust, the GPU usage dropped at times to 20-30% and the fps to 30ish, if the GPU usage was all the time at 100% the DX11 frames would have been higher, probably the same goes for DX12, but Afterburner doesn't work under DX12 so i couldn't see the GPU usage.

What's there not to trust? The demo might very well be CPU limited at some places.

^ At end outside it looks to be some sort of streaming issue API limitation.

It is very CPU demanding in both DX11&12. When I disabled texture streaming, fps still dropped drastically at end and recovered as camera moved closer. (GPU utilization there was really low) Performance for DX11 and 12 in this demo is very similar, DX12 does not improve on anything there, maybe UE4 does not use native DX12, but DX11 inside DX12 envelope.

No, it uses DX 12. The fact that it uses that library doesn't mean the whole engine rendering code has been changed to take advantage of it. Edit: here you can see why your GPU usage tends to be low http://i.imgur.com/D32pcow.png The engine is drawing over 8000 primitives per frame, while in playable games this is usually kept under 1000 or so. This is where the driver overhead comes into play and it's exactly what using DX 12 allows the devs to improve. They just haven't gotten around to it yet. Plus the scene has over 8 million triangles, which is pretty crazy.

What file can I set a resolution and other settings in? With whatever the default settings are I'm getting typically over 120fps, it only drops when the GPU usage itself drops, so I don't know if those moments are CPU limited or if something else is going on with the draw calls or what. Oh and it set a new record for heat for me, 66C at its peak. My card became loud as **** and the fan hit 92%. Edit: LOL I was running it in DX 11 mode, my OSD doesn't work in DX 12 mode. So the DX 12 shortcut reminded me that UE programs can have resolution/etc set through that. Well that answers my question... assuming it works as it used to. ... and yeah it works, -ResX=2560 -ResY=1440.

What I meant is that UE may use simplest of implementations. source Btw, it looks like you managed to successfully import infiltrator into UE4. I could not do it with standard UE4.9.1. Did you use special build or standard? Did it require some modifications?

Just download it in the launcher and then go to the "library" and under "vault" section you should find the demo. Then just launch it. Launching it the first time can take a long long time since it's rebuilding all the shader caches for your computer.
