Should we be happy at 30Hz?

[Underscore]

I think I have now settled on I'll not be seeing 90FPS with all the detail and resolution I would like with technology available for some years to come

 

Therefore I am trying to get myself to come to terms with 30Hz on a G2 is fine..... to be honest I can't tell the difference from 45FPS and 90 is not attainable - just seems to be some sub-conscious telling me I should not be happy about it lol

 

Am I the only one like this or are others happy with 30Hz and reprojection filling in the gaps?

I'm surprised you can't hit 45 with your specs if you are using OpenXR and OpenXR toolkit with your G2. If you can't tell the difference, I guess that is all that matters, but if you are locked at 30 you aren't giving yourself anywhere to drop really when missions get intense. With unlocked motion reprojection via OpenXR Toolkit, at least you can step down from 45 to 30 in fringe cases and make sure you are maintaining a smooth experience throughout.

What is “unlocked” motion reprojection?  Is that the auto asw in the ott?

I'm not sure if unlocked motion reprojection works with OTT, but with other headsets, like the OP's G2, if you use OpenXR Toolkit with unlocked motion reprojection, your FPS will step down to a locked 30 from 45 if something gets too intense to maintain 45. It's nice to have the additional step-down if needed and keeps game play smooth.

The biggest downsides I experience while using motion reprojection are:

1. "ghosting" contacts that are moving across my field of view, which makes it hard to ID a warbird within visual range. The bogey is quickly, constantly jumping a little forward or backward with each frame as the actual position is updated every other frame.
2. And the propeller artifacts can be a little annoying to track a target through. This seems to be more an issue in certain RPM ranges. 

I do use reprojection "always on" at this point, because without it the experience is just not smooth. Rolling around in an engagement the framerate hitches pretty badly making it near impossible to keep a tally on something below you. With motion reprojection on, it's MUCH smoother, but then the two issues above are present.

But, I'll deal with those issues until VR rendering is sorted out better.  And I have no doubt it will be, between squashing bugs in the new mutlithreaded code and new techniques and enhancements that are in the works.

I've run my G2 at 60Hz since OpenComposite No reprojection (not necessary). I maintain near solid 60fps, with high DCS settings(no MSAA) and 80% render in OXRTfWMR.

To this day, I do not notice any 60Hz flicker some report. Any slight amount is also eliminated by using the Light sunglasses in OXR Toolkit.

 

I have an RTX 4080 enroute next week. Can't wait to see how much further I can push it.

G2/4090/13700k here.

I used to use 45/30fps with MR and thought I was quite happy until committing to a good run with 60hz which I have adapted to and stuck with. Little things like appreciating an F3 flyby or a smooth merge in a dogfight make a huge difference to me when running at full refresh. Also clarity is overall much better and deeper somehow.   

I now have a pre-order on the Pimax Crystal which will likely push me back into reprojection. Might be a deal breaker that. Guess we'll see when the first DCS reviews with it come out.

Being able to keep above refresh rate is an absolute game changer for DCS.

It can be hard though, even 60fps needs hefty hardware and compromises to achieve it; 90fps more so. All being well the upcoming implementation of DLSS will enable the magic value of <11ms to be achieved for many.

Regarding reprojection, it's going to get better soon for WMR openxr users all things being well. 45 vs 30 has always been practically impossible to differentiate for me during testing. However there is a slight clarity loss and the artifacting to deal with with reprojection in general.

I've been contemplating the Crystal... but for now I'm perfectly happy with the G2. Especially since upgrading to RTX 4080.

For Quest you can try the adaptive option for ASW in OTT

In one word: NO.

I accept it's very subjective, but since the days of the CV1 when 90fps was easily achievable in DCS (a deferred rendering engine "upgrade" put an end to that), I remain of the opinion that running in reprojection is not "true VR".  Reprojection was always supposed to be a stopgap measure for the exceptional occasions when a system could not cope with extreme loads, not the default.

However, we must play the hand we are dealt... grumble...

I now aim for 72fps on Quest 2 and can mostly manage it with low settings.  3080ti.
