I got the showdown demo.
First it failed to build because two nodes in the blueprint SurroundPanner were wrong. An easy fix.
Now it builds (Shipping) but when i try to run it I get…
---------------------------
Message
---------------------------
Failed to open descriptor file '../../../ShowdownVRDemo-Win64-Shipping/ShowdownVRDemo-Win64-Shipping.uproject'
---------------------------
OK
---------------------------
Any ideas?
=== later…
Ok, the Shipping build does not run at all. If I build for Development then it does run but at 1 frame per second.
My machine is i7 3.3 Ghz, 6 core. GTX 980 graphics. So it’s plenty powerful.
Oculus 0.7 SDK and Runtime.
=== And more later…
Ok. If I reboot and run the Oculus config and show the test scene, it works fine.
Also the Oculus SDK demo scene (villa) works fine.
If I then run the Unreal Showdown demo (not in the editor) I get garbage in the oculus. For example blocks of randomly colored pixels. I also get 1 frame per second.
If i then go back and run the Oculus test scenes they are also 1 frame per second and sometimes have garbage.
==== More the next day…
Ok, so I updated the NVIDIA drivers to the Oculus 0.7 compatible level.
That cured the corruption on Win10. and the 1 fps bug.
Still, on a laptop with power management turned off I get 75 fps plugged in, 40 to 50 fps unplugged.
My demo scene is the First Person Shooter sample scene with the DefaultScalability.ini file form Showdown.
