[1.39.0.0] SU16 Beta Survey - Performance (Xbox)

My settings are:-
RC8
Bing data On
Live Traffic/AI traffic off
Static aircraft 50%
Airport vehicles 20%
Workers 10%
Ships 100%
Road vehicles50%
Fauna 0%
Live Weather On ( slight clouds setting used for all tests for consistency )

I don’t have any of the City updates installed - most of the WUs
I have the 737-8, 777f, CRJ, F28, Sh360, BN Trislander all installed. 51 addons as i think as you get to well over 50, loading times start to go downhill..
No third party airports.
Each flight different - if I have time cold and dark, if in a rush from runway. I use Simbrief and Navigraph for flight planning.
Can’t guarantee this will work for you unfortunately but I’m getting consistently good results - so far (!) :slight_smile:

What rolling cache do you have? I have always kept it off and I’m having trouble with SU16 latest beta but it seems as though that it’s working fine for people who have at least an 8Gb rolling cache and possibly even 16Gb

Thank you all for the info!

I have kept all my settings from SU15, so the rolling cache is set to 0/turned off. I will turn it on, set 16gb and check the results.

Joined for a night and it was laggy (reserved space cleared beforehand). Back to the live version. I hope this gets fixed.

I joined the SU16 beta and I have to admit I’m pleasantly surprised.

I was able to complete three flights (on different days) and multiple takeoffs/landings with the A320v2 without a single stutter, even taking off and landing at highly detailed airports like KMCO or KATL.

The render distance is much better; you can see the runway from about 15nm.
And at night, the lights are crystal clear; you can see other aircraft in the distance, both day and night!

After the first flight, if you try to perform a second one without restarting the sim, you’ll notice that the memory is degraded and the render distance isn’t as good anymore.

Photogrammetry is still pretty poor in areas like NY or London, but with PG off it works very well.

I have the cache enabled; I normally set it to 16GB, but yesterday for testing, I increased it to 32GB. I can’t confirm any improvements with the increase, but I also haven’t had any problems.

I didn’t notice any problems regarding "time loss"h, but I also didn’t take any flights longer than 1 or 1.5 hours. I’ll keep an eye on this.

Sounds like you’re having an incredible experience there. Seems like a real chore however to download all the world updates again after resintalling the game.

I actually had moved the game as-is from my internal to the external, in case I ever want to move it back again to play. It was just under 300 gigs when I moved it (included all the updates and my add-ons plus the rolling cache file), but when I moved it back to the internal, it only installed the base content and add-on support. All the WUs and third party content plus rolling cache gone God knows where.

So I’m hesitant to install it again because if I need to move it temporarily to create space, I’ll only get the base game back when moving it to the internal SSD to play.

Any bright ideas, lol?

Honestly, if I hadn’t had constant CTDs with SU15, I would have continued flying there, I was forced to come here on 16, where at now I have never had a CTD, finger crossing . If you don’t have problems with SU15, I recommend staying there.

Ok, I did 6 flights with rolling cache set to 16gb and the game looks a bit smoother. It still stutters a bit with the 777F, but it is quite acceptable now. Time loss is still present, but seems like it is not as bad as it was before - on 3 flights I did not lose any time, 3 other flights were between 1-3mins / hour.

I will try flying in different areas now and see how it goes, because almost all of those flights were between central/north Europe and northern Italy since I wanted to check if I will get a CTD - northern Italy was almost a guaranteed CTD for me before SU16 beta. With SU16 I did not get any CTDs yet and I already did ~20 flights with PMDG 737 and 777 (all flights were 70 - 180 minutes long).

Same settings as I’ve listed before on this thread.
This time used the stock CJ4 with proline avionics on a short hop KORD KCID.
Take off wasn’t quite fluid - a couple of slow motion episodes on acceleration and rotate. Climb out OK but very choppy panning around flight deck. The choppy panning stayed until 10 nm from TOD when it all became smooth and fluid.
RNAV approach to RW31 - all smooth until on short final when there was a slow motion like episode on flare out which was disconcerting… on roll out very stutters, choppy panning around flight deck. Slow motion episodes frequent on taxi in. ( note - is there something going on with new ground textures perhaps?)

Ended flight - had lost some time obviously, then did what I don’t normally do to stress the simulator and tried to load a different flight with different aircraft. ( I normally exit the sim and restart). Immediate CTD.

So- my own thoughts- key for Xbox users is using aircraft that developers have tested and optimised on Xbox. The difference in performance is night and day.
From a very selfish standpoint the aircraft I fly most in the simulator work brilliantly in this beta build, But getting real, many users don’t have these third party aircraft to fly and many of the stock planes or the un-optimised ones Ive tried so far don’t work anywhere near as well and - in my view - don’t seem to perform as well in this beta as they do in SU15.
So I’m changing my vote based on these latest tests and I would now say that although this beta is a very promising start, some refinement is necessary on Xbox before it is released commercially..

Contrast to last flight with the CJ4…

CRJ-1000. LEMD-LEAM at FL310.
Breathtaking scenery with great LOD - much improved from SU15.
Silky smooth from taxi out at LEMD to parking and shut down … including final and short final and taxi in from RW25 at LEAM.
Flight was an absolute joy and there was no time lag on the 46.25 sector.

I hate to say this after my glowing comments about the performance of this build earlier, but this beta is exhibiting some VERY strange performance behaviour that I can’t quite figure out… Some aircraft are performing beautifully - Very smooth fps, excellent LOD, etc. while many others are virtually unusable due to HORRIBLE fps performance. The strange thing is there seems to be no common factors causing these certain aircraft to perform so poorly.

The sheer amount of my favourite aircraft that now cannot be used due to abysmal performance is leading me once again to consider leaving the beta…

The FSR TL3000, for instance, cannot be flown enjoyably in this build. As soon as the battery and avionics are turned on, the sim becomes a slideshow with endless choppy frames both on the ground and in the air. Meanwhile the COWS DA40, which uses the same avionics suite, performs beautifully. Same goes for the SWS RV-14, which again uses the same avionics suite, and presents with the sim becoming a slideshow. Switch over to the //42 Kitfox, and you get buttery smooth performance. All of these aircraft use virtually the same avionics, and have about the same level of detail, yet some perform perfectly while others cannot be used. Stranger still is that all of the above aircraft exhibited about the same level of performance in SU15… What is causing this??

I’d be tempted to say it’s related to Garmin glass panels, but then if you try to fly the Black Square TBM, or the FlightFX P180, they also present with a stuttery slideshow.

It gets even stranger when you load up the Aerosoft CRJ, a much larger aircraft with arguably far more advanced systems than any of those mentioned above, and you get some of the best performance ever seen in the sim…

Totally agree - I am seeing exactly the same as you…. Can’t work out a common factor yet…

Just Flight F28 - smooth as silk, joy to fly as the F28 was known to be…
Cockspur C510. Jerky and horribly stuttery - until in the spirit of experimentation I dialled down the map detail on the MFD to 1. ( the C510 has a Garmin G1000 system fitted) Then it became almost as smooth as the F28. Haven’t had time yet to see if this works on other aircraft ( obviously it won’t work with analogue flight decks like the Blacksquare ). But it certainly seemed to make a huge difference on the C510. Will do a bit more playing around when I next get some time freed up.

Puzzling…..

This build has definitely gone backwards. Prior to the last update that fixed the WASM exclusion it was working beautifully and haven’t seen it perform as well as that perhaps since its release. Is it that WASM has had such a negative impact on performance that we are seeing the degradation in visuals and performance? I didn’t notice in the release notes that much else changed?
The draw distance seems to have reduced significantly so am getting blurry ground textures very close to the aircraft which wasn’t the case beforehand. As well as it suffering in this way I’m also experiencing worse performance! So what’s happened is it has managed to look worse and perform worse! How has this happened? Surely you trade one for the other? The mind boggles. Always seems to be one step forward and two rather large steps back.

I always run my Garmin panels with lower detail (usually just keep airports, airspace, and nexrad), so not sure this is a factor for me. I did read elsewhere that some users have had success running a rolling cache (I usually do not). Tried setting a 16Gb rolling cache, and did see a tiny bit of improvement on these stuttering aircraft, but nowhere near an acceptable level.

There is definitely something going wrong behind the scenes with these aircraft, and they must all have some common factor that’s causing this, I’m just completely stumped as to what it could be.

When I get some more time I’m going to do a bit more playing around. I’ve played with MFD map detail before and it never made much difference- this time it did. Not sure what’s going on yet. I also noticed that exiting flight deck for an external view then returning inside the flight deck can also result in an LOD drop.
A few odd things going on for sure and more testing for us all to do if we can…

Seems legit to suspect garmins gps’s as performance killer in su16 :thinking: big update of many of them came with su16

EDIT:
small test BS caravan - different setup:

  • no gps - hyper performance
  • 530/430 - good performance
  • GTN750 - huge performance drop

2nd test BS TBM bad performances in either gps setup :thinking::smirking_face:

Really good find! I hadn’t considered swapping different avionics setups through the same aircraft - Black Square is the perfect testbed for this. I’ll be doing the same this evening after work.

Doesn’t quite explain the FlightFX P180 or default CJ4 performance hits though, as these use the ProLine 21 suite, which I don’t recall having been updated with SU16.

With some heavy aircraft like the avro rj I still find it hard to get a decent LOD and at airports still all blurry. This problem is less present with aircraft such as the crj and 320 v2. The 738 still struggles a bit, something needs to be done to optimize wasm aircraft.



Excellent test…
