DCS World - All things VR

I did a couple of quick experiments to see. Here’s where I got to:

I used the exact settings as shown in the screenshot, but on a Nvidia 1070 8GB, i5 @4.5GHZ, 16GB RAM, SSD etc. I used the Oculus Tray tool to monitor perf overhead.

I used this mission, where I hover checked a Huey, rose to about 1000 feet and circled Nellis. Obviously an intense test, but no point in messing about :slight_smile:

  1. With everything left as is, about 32 fps, so next stop Pukesville! Not unexpected, as that 1080ti is a beast and not cheap.

  2. With Deferred Shading off but nothing else changed about 39 fps, so still a White Telephone Bowl trip but getting closer. So Deferred Shading very roughly adds about a 25% perf overhead as a guide.

  3. Shadows set to ‘Flat Only’ (from ‘Medium’). Deferred Shading off = 45 fps with a 20% perf headroom.

  4. Shadows set to ‘Flat Only’ (from ‘Medium’). Deferred Shading on = 39 fps with no headroom. Technicolor yawn liquid again.

  5. Shadows set to ‘Off’, Deferred Shading on = 45 fps. Tolerable, but not much headroom if things get busy.

  6. Shadows set to ‘Off’, Deferred Shading off = 45 fps. Tolerable, but headroom if things get busy.

So I prefer the lighting of Deferred Shading (especially with a gamma adjustment, beautiful) but on a 1070 for DCS 2.1 if you fly below 1000 feet then it’s not really doable unless you take off all shadows and try not to go anywhere with lots of action. Plus that’s NTTR and not the more demanding Normandy.

If you turn off Deferred Shading then you can pretty much manage a baseline 45 fps with ASW kicked in all the time for most of your time.

Now, off to vomit. :face_vomiting:
