Hey guys.
Last week Epic released their Kite Demo for the masses.
Unfortunately, the provided executable is capped at 30fps and since it is not a dev build you cannot uncap it.
Even if you try the KiteDemo.exe -bUseVSync=False command it still does not work.
So what I did, is build a dev version, which allows the use of the console, so we can properly uncap the framerate and use it as a benchmark.
You can download the 4GB file from the following links. Use latest Winrar to unpack.
Google Drive
The file extracts in it's own "kite_dev" folder and needs 9.1GBs of space for extraction, since it is highly compressed.
How to use.
- Once extracted, you will see a runme.bat file.
- The file runs the command "WindowsNoEditor\KiteDemo.exe -bUseVSync=False -ResX=1920 -ResY=1080 -FullscreenMode=1 -Fullscreen", but you should always view what a .bat file does, before running it.
- The -ResX=1920 -ResY=1080 obviously controls the resolution, which you can change to what you want (personally I have only tested 1080p).
- If you don't want to run the bat file, you can run the executable KiteDemo.exe itself and then press alt+enter for full screen. You don't need to run the .bat to uncap it.
- Once the demo has loaded (it can take a while-don't close it if it shows a black screen for more than 2 mins), it will be showing a real time rendered field, with a still camera.
- To uncap it, you can press tilde (~) to bring up the console.
Then issue the following commands:
t.MaxFps 100 (you can use higher than 100 of course-was not needed for my cards)
r.vsync false
- Now you can press page up and it will go to the next scene, which is the actual Kite Demo. When the run starts, you can use fraps to gather framerate data and post your result here.
Sounds like a lot of work, but I believe it's worth it, since it will make your system scream. People are reporting that the demo itself is a decent gpu overclock tester.
To test this, I made two runs and posted them on Youtube (spicy wallpapers alert :awe: ). The vids are recorded with an external digital recorder, so what you will see is pure performance.
UE4 Kite Demo Uncapped Benchmark 1920x1080 GTX 970 @1.5Ghz Core i5 2500k@4.8Ghz - 37fps
UE4 Kite Demo Uncapped Benchmark 1920x1080 7950 @1.1Ghz CORE i7-860 @4Ghz - 16fps
I would appreciate anyone's participation but I am really curious how the Fiji cards will do in this one.
Thanks.
ps As a side note, what I found interesting, is how different the two cards work the cpu.
These are the cpu usages during the run, also shown in the above video links.
It seems that on the Nvidia card, there is much better threading. It is curious considering that the 7950 system is running on Win 8.1 while the GTX 970 runs on the older Win 7.
I'd request Radeon owners with faster cards, to look into this and report if they see any cpu limits in this, or different cpu load.
I went back to some other UE4 testing I did on my 7950 and saw the same cpu behavior. Maybe we should alert AMD about this?
