Just get a pre cleaned up driver and don't waste your time.

I have a feeling this is a stupid question but does OpenXR // Open Composite work in DCS wit Pimax 8kx? 

[edmuss]

Currently I don't believe that the pimax headsets support OXR natively. I think it's possible to use pimax with OC but it adds in an additional translation layer which in theory will hurt performance.

From what I understand, the OXRTK devs are planning on working with pimax hardware. I'm not sure what the end goal is but I suspect it will be to get OXR supported natively.

Might want to ask this guy.

Thanks! I'll check it out.

To be fair he's getting >90 fps using a 3090ti at approximately 75% G2 resolution.

I think I can almost get performance like that high over water with my 3070

Right. I found myself saying, "try that over Caucuses in the A-10 or Apache"

Yeah, I have to agree. He is idling the 12900/3090ti with so much overhead that when there is a frame time spike it doesn't go above 11ms. Each to their own I guess - amazing performance at 3060-like levels of visuals 

Maybe a life in aviation made me a little more cynical than most. But, why do I have the feeling that his video is primarily designed as a sales strategy towards getting his followers and viewers to purchase a Pimax Headset?

[edmuss]

Just a quick test, A10 @ angels12 over the eastern sticky outy bit of Cyprus and I'm getting 80 fps.  G2 @ 75% with the same FFR and the same settings except I have standard clouds not high.  Not sure what map he's on, guessing its PG which I don't have.

I'm not suprised that he's beating refresh rate given that he's got at least 2500 quid invested in the hardware

edit: @ZoneySD yes it is possible to run DCS via OXR with a pimax. Performance wise Vs SVR I don't know if there's an increase. The video posted proves it can be done but the hardware used is so capable of brute forcing the frametimes that it proves nothing.

MR... try switching it off in OXRDT, and leaving it unlocked in OXRTK ... it seems to work ... better ... much better...

As in disabling MR altogether? Which bit works better?

I have it disabled, running at 60Hz... it's heaven.

Yeah the 60Hz is the key, beating refresh rate makes VR all the better. 60Hz just moved the goalposts to make it easier to achieve

[zildac]

Sorry the 60hz thing just hurts, I wish it didn't. Even a CRT monitor at 60hz these days is painful. Having two of them strapped to my head and a few CMs away from my eyes is even worse

[edmuss]

Yeah it's a shame that there's not another distinct step like Oculus does with the 72Hz, might open it up a bit more for people.

[speed-of-heat]

No not disabling all together... Just in OXRDT, leaving it enabled in the toolkit.  I didn't think it would work... But 45fps little or no wobble

I think it's luck of the draw.... I don't even notice a flicker.

You're right. For me personally, it's not comfortable

Ah so set to enabled in the toolkit but disabled in the dev tools, not tried that will have a look

I was just coming to comment on this. I usually keep it ALWAYS ON activated in the OpenXR Developer Tools for Windows Mixed Reality, so I can use the  "all steps" of MR in DCS (90/45/30/20). But this morning I decided to turn it off in the app and activate it in UNLOCKED mode in openxr tools 1.1.0 and the MR is much better,  much, much, much better!... as it says "SoH"... So good!!.

Man! That's the ticket 

[edmuss]

I don't see any difference between OXRDT MR disabled with OXRTK MR always on vs OXRDT MR always on with OXRTK MR always on.  I still get distortion of the pitot tube, wing ordnance and MFD glare shields in the A10 and bubbling around the mirrors and on the ABRIS in the KA50; it's the same with both options.

That said, it is certainly better than it was when OC_ACC was first applied to DCS.  As a matter of fact, on a whim I re-enabled MR a couple of nights ago and noticed that it's far less artifacty than it used to be.  Still not as good as SVR but certainly far more useable
