i think the problem with this though is you lock your Rift to that for anything you play. So things you may have better fps with because they are more optimized will now have less

Most likely indeed.
In fact I would say anytning below 40 native is below my threshold to tolerate.

I have and tested the Pimax 5k at 32, and it was simply not enjoyable.

You can use Oculus tray tool and setup profiles

Yep I can tolerate ASW of 40 fps and to me really still looks pretty good. Drop much below that and is a no go for me.

For me this works flawless, no artifacts and the 27 fps feels actually smoother then the 40 fps.
Even in mp, it never felt so smooth tbh.

Thanks for this will try it tonight. The current state of VR in DCS has really removed my interest in playing

I tend to fly instant action or custom made air-to-air dogfight missions which typically only have 2 to 8 aircraft, so I can fly vr fairly well without this kind of trick. But in multiplayer or in certain missions that require a lot more horsepower, I have to turn a lot of settings down.

A particular instant action mission I use as a benchmark for judging if my settings are good enough for multiplayer is the MiG-15bis instant action dogfight over Normandy. The Normandy terrain is not particularly kind on performance, but this is a high altitude fight with lots of aircraft on both sides and contrails everywhere. With high settings, I get a slide show. Even with setting dumbed down as low as I am willing to go, the fps can get low.

So, I tried this MiG-15bis mission with this 27fps override. I am impressed. It doesn't solve everything, but I can run the settings up much higher including shadows and mostly maintain the 27 fps steady. There can be some ghosting, but it seems like a lot less than with 40 fps. I expected the 27 fps to look choppy when rolling at high rates. I can easily judge refresh rates from 30 to 45 to 90 by how they look at max roll rates. I am impressed. 27 fps would normally look like a slide show to me, but this looks almost as smooth as 45 fps. Overall, I can enjoy this mission a lot more with higher quality and fairly steady 27 fps rather than at low quality and an unsteady 40 fps.

I just wish DCS World could be optimized to for multi-core so that rock solid 80 fps would be possible at max settings... because Aerofly FS 2 is utterly amazing in VR with its photoreal world at a locked steady 80 fps with max quality settings. Of course, they have no AI of any kind unless you get a mod for the Florida Keys, and the terrain is 100% texture based: no waves or wakes, just hi res photos. But I so badly want to see DCS World run at that level and do so with a headset that has a full, natural field of view and pixels so small I can't see them. One can only dream.

In the mean time, I have to choose between quality and fps to enjoy DCS World in VR. Or be bored flying circles with no one to dogfight in Aerofly FS 2.

So, I did a follow up test, where I played the exact same mission with the exact same settings, but turned ASW off. With ASW off, my frame rates had three stable points: 70-80, 40-42, and 27-28, so Oculus is obviously doing some kind of VSYNC that I don't have turned on via the game or the gpu driver. Playing with ASW off did sometimes have a slight stutter, but for the most part, it looked as good as playing at a steady 27 fps. More importantly, virtually no ghosting. So over the next few days, I am going to start playing with ASW off and see how that does in the missions I typically play offline as well as in multiplayer. If it gets ugly, I will try 27 fps again. But I suspect my best bet would be to play with ASW off and my settings lowered for speed. Staying at 40 to 80 fps with no ghosting would be better for me than having shadows and hi res terrain textures.

Played again with my previous low quality/high fps settings mixes with ASW off: for dogfighting this is the way to go. I didn't see stuttering or ghosting, things just look a little uglier when I stop to sight see.
I think the 27fps setting would be better for non-combat missions where you are more focused on the map/ground objects rather than rapid pitching/rolling/turning in a swarm of aircraft.
