VR performance after 22nd Feb update.

[Qcumber]

I know this is early days and we all go through the "placebo" or "WOW" effect with a new update (or the "nocebo" moan) but has anyone else noticed a significant improvement in FPS since today's update? 

[Glide]

Me too.  I'm still shaking my head. Those terrain processing improvements are awesome.  It seems the only thing limiting my settings is my VRAM.  Still testing.

My initial tests show an increase of about 10-20 fps. I normally get 35-45 FPS in 109 free flight over Cairo. Tonight I got 50-72! Amazing! 

@GlideAre you using a headset with eye tracking? What GPU are you using? 

[Glide]

@Qcumber Pimax Crystal Sim with the 3080TI. I turned up textures, shadows, and filtering, and it didn't even blink.

I'm using a QP. It's early days but I do wonder if this is something which benefits DFR the most. 

I am using DCS settings at max settings and DLAA.

Marianas were unplayable for me in VR before, currently I have a constant 72 frames here over Guam  (max for 72Hz Quest Pro, MSAAx2), amazing, before it stuttered like hell here, no any 1 FPS worse, stable! Maybe finally I will buy @Reflected campaign for Huey, I didn't take it because of the bad FPS on this map.

I checked all maps and all have recived boost after Today's patch, amazing (still only the South Atlantic lags behind, unfortunately @Raz_Specter pretty please!).

I think its a great update if we talk about performance.

Just tested Marianas and had great performance. The Lagoon Patrol mission was a steady 72 fps (compared to about 55) and a free flight over Guam was 50-70ish; much better than before. I've not tested The Channel or Caucasus maps yet but Normandy, Syria, PG and Sinai are all looking good so far.

At first I saw a about 10% increase in frametimes, but now I think its more than that. No sure yet how much. Anyway, the bigger impact for me is, that the CPU-related occasional stutters (frametimespikes) have gone, which gives me a far better experience.

Only yesterday, I was a bit mad at ED, since throwing costly harware at DCS still offered a only mediocre visual experience and today they improve quite a bit!

Theres also a NVidia update as of yesterday too.

 

[Raven (Elysian Angel)]

Mostly I saw an increase of about 10%. The lowest gains are in the Caucasus map: that's probably because it's the oldest map and because I use Barthek ground textures there and Taz trees.
The highest gains are on the South Atlantic map.

I could actually run my Crystal at Maximum with DLAA with my 3080Ti with great FPS and only one or two hiccups.  I've gone back to my earlier strategy of keeping the FPS as high as possible, so I don't mind DLSS Performance.  It's always tempting to make the terrain look beautiful, but I want all my compute cycles going to flying.  The Viper is an absolute hoot now.  I actually managed to get a legit gun kill on a Mig-29S yesterday.  Usually I can't catch them until they quit and head for fuel.  That's a huge improvement too.

I need to try out DLSS after the update. I am going to try pushing up the DFR centre res as high as possible and use DLSS balanced/performance to see if a combination of high res and high fps reduces DLSS artifacts. I know it sounds mad but it just might work!

I'm running the aero at 39ppd (1200x1200 focus 2192x1880 peripheral) with the peripheral hacked down to 0.6 which results in 1316x1128. DLSS quality and I see virtually no DLSS/DLAA artifacts, I am now hitting 90Hz refresh most of the time unless over Damascus etc. in the hind in which case it's 75-85fps.

Your 4070 should be about the same as my 3080ti (in theory) so perhaps adjust the values to match and see what happens

That sounds positive. Maybe my idea wasn't do mad after all. I'll try to mimic your settings and see how it goes. 

[edmuss]

Now of course with the qpro you might be beyond the point of diminishing returns with the 1200x1200, at some point the panels will become saturated as they're physically a good deal lower resolution than the aeros.  With DLAA I find that there is no perceptible shimmer/resolution artifacts on the peripheral, perhaps just wind it down so it's at 60% and see how it goes.

I know that the QVFR numbers work slightly differently to VFR but the concept is the same and whilst beta testing QVFR I found that performance was pretty much en par once the resolutions were matched.  My reasons for using VFR over QVFR is that there is an eye tracking data bug between varjo base and QVFR and there is a higher CPU load with QVFR.  Functionally though, they're pretty much the same system

[nachomaga]

I just tested two quick missions, Apache Longshot in Syria and F-15E Ramp start in SInai and I can confirm that I notice a big improvement in FPS, amazing.I have to do more testing, but pretty happy with the results. As other said, with DLSS update, Caucasus map was big improment in perfomance, but not the other maps in my system. With this update, ED seems to fixed this.

Reverb G2, 12700k and 4090.

Yes. I see your point. There is a maximum perceived resolution and sharpness which is around 3500 or so pixels on the QP (max res in oculus of about 2700 and x1.3 in OTT).

However my hypothesis is that the higher res image would reduce the DLSS artifacts. So if I push centre resolution to an equivalent of about 4800 across the whole display (but limited to about 0.25 centre) and the periphery at about 1200 pixel equivalent, then use DLSS balanced will it give similar results to a lower centre res image with DLAA but without any artifacts.

Yes, high resolution is great.  Strangely, I ran my Pimax without any AA when I first got it.  It was super fast, and not very aliased.  However, DLSS cleans it up so nicely.  I also keep my frames small.  That means Textures Medium, Terrain Textures Low, Shadows Flat, Terrain Shadows Off, AF off, Visibility Range Medium.   This is just enough eye candy to make the terrain look real without wasting any resources on it.  The cockpits look great too. There are "mistakes" as that fellow from Digital Foundry, in DLSS/TAA, and you just have to live with them until Ray Tracing comes out.

Beware of DFR / Quad views over cities. This causes CPU clogging, which is good at the beginning, but FPS becomes worse over time. This is described by mbuccia himself. I don't recommend this in DCS. Its a separate topic about Quad view. Maybe this 22.02 solved this issue for DCS. Before it was present.

Not had any issues flying around Damascus, also I'm not using quad views but varjo foveated which is lighter on the CPU anyways.  Worth remembering though if there is unexplained performance loss

I don't seem to have a problem with QuadViews over cities.  Not sure what I'm doing right, but it's smooth as silk for me.  I have Turbo Mode, Compulsive Smoothing, Eye Tracking and QV enabled in PimaxXR.  No Smart Smoothing in the headset.  120hz, Maximum resolution, DLSS Performance.

It seems to work. Using VD at Godlike with 0.25x0.25 centre at 1.8, periphery at 0.5, DLSS-performance the image looks very good, similar to DLAA, but better performance; a fairly steady 72 fps. Hardly any bleeding/smearing. 

[WipeUout]

My test track (FA-18C over Caucasus) is 10 FPS better.  Only thing is that for all my tracks with FA-18, there is a horrible shaking of the airplane, because of the new flight model I guess.  Other than that, also seeing reduction in CPU frame time of about 0.26 ms, which is not negligible.  Welcomed improvement, thanks ED!

[-Sledgehammer-]

yes, much better. i could run the q3/4090 on pd 1.8 dlss and on quality and everything cranked up. 72 fps steady.

even sinai cairo is fluid without stutters. marianas though is still a slideshow… im flying helos 

significant…thank you ed.

Could any of this be attributed to Map optimisation do you think?
