I'm also suffering from CTDs, but I guess it's expected when you have a beta build.

Overall, though, I am very pleased with the performance. I just upgraded my GPU to the 4070 Ti S paired with a 5800X3D, and I'm able to fly with ultra settings and TLOD at 250. NYC, LA, Seattle, Paris - no FPS issues whatsoever, and with FG, it's heaven. I have noticed, in most scenarios, my VRAM is hovering around 11GB. At 3rd party airports, VRAM jumps to around 13GB on average. There is one setting that does impact FPS and smoothness, and it's AI. I've decided to leave it off and continue to use the LVFR static package.

I would be interested to know if those experiencing CTDs have used the DLSS Swapper utility. I'm sure the majority won't have used it, but there may be some that have.

Indeed I was using it to update to the latest DLSS version whilst in the beta (still using it). Hard to know if this is related as there could be almost an endless number of issues causing CTDs. 

I remember suffering from frequent CTDs in a previous beta, and discussed various potential causes and solutions in a thread over at the official forum. All sorts of suggestions emerged, like audio driver issues, RAM errors, etc etc etc. IIRC the thread ended up having 1000+ posts...

I'm getting CTDs every flight (even with an empty community folder). Never used the DLSS swapper

I was getting CTD with 737 every single flight in the beta without fail. 
 

I noticed that using the swapper thing left a rogue file lying around as well as the two dll files.

I removed this, and was able to complete a flight with the PMDG.
 

Maybe a coincidence, but I was getting a CTD every single flight, and then  was able to complete one after removing. I might try one more this evening and see if it crashes again but it’s already gone 1am!

talking about stutters or the lack thereof and to put focus once more on constant frametimes rather than mere fps:

looking back again at pre-SU15 beta times back in 2023 this is what we had, RTX 4090 framegeneration or not:

 

Frametimes:

SU15 beta and similar to Captain Piett's research: look Ma, no stutters because of near zero frametime variances as never seen before in MSFS: frametime variance under 2 milliseconds for 99.53% of all frames= no stutters noticeable.

 

Framerates;

135 fps @ 4K, LOD + TLOD = 200, graphic settings high/very high, TAA, NVidia framegeneration, C172 over pacific northwest 

 

great CPU load distribution on all 8 cores: 

 

yes I confess: this is not exactly your PMDG over KJFK scenario, but the smoothest stutter free experience for General Aviation pilots.

when I signed up for the very first MSFS beta flighting in September 2019 and we got the first water-marked beta finally in January 2020, I was totally overwhelmed, but never expected we would see this level of optimisation and performance that we enjoy today. I remember the naysayers back then: "wait till the airliners and large airports are available. you will be stuck at 20 fps". coupled with the WorkingTitle avionics, this unprecedented performance is second to none and is what keeps me flying MSFS 2020 for 4 years now, nearly on a daily basis. I can tell by my electricity bill. 🤣

benchmark tools used:

presentmon by Intel https://game.intel.com/us/intel-presentmon and CapFrameX https://www.capframex.com/

Hi all,

I enrolled in the SU15 beta last Thursday. I also see a lot more smootheness and less stuttering while panning, with one exception though: the Inibuilds A300. Stuttering has become worse to the point where a few minutes after loading the flight just panning around in the cockpit becomes a slideshow. 

I must admit that I tested this at resource heavy KJFK and the newly released KMIA airports with FSLT traffic running. However, both airports/scenarios work just fine when in the Fenix or PMDG cockpits. Has anybody else experienced the same?

Kind regards,

Nico

The performance of MSFS for the level of graphics you get, is just out of this world for a civilian flight simulator. Nothing comes close to it, especially when frame generation is used.

Usually, you get very good FPS but very bad graphics. Or you get very bad FPS but very good graphics. With MSFS, you get both good graphics, and very good FPS!

I haven't had a CTD for many months prior to now.  First two flights in SU15 beta both ended with CTD's.  Same exact flight, at almost the same exact point in the flight....interesting.  I'll stay on the Beta for now to see if they persist. 

I feel sorry for all of those experiencing CTDs with this latest update. Just for anyone still wondering about jumping aboard the beta (and being prepared to rollback to the pre-beta release if things don't go well), I've been using it for the past week, using DX12 and I've had no CTDs so far, nor any visual glitches as a result of using DX12 — just all of the benefits of the improved performance (and they are huge wins btw) and the G3X.

I hope they've already identified the CTD cause(s) and are working to fix them in a beta update soon.

I you haven't already done so, vote on the topic and post a report using info from event viewer. So far only 54 reports... The topic has been "feedback-logged" though.

This is indeed quite an accomplishment by Asobo! They've certainly come a long way during my 1yr hiatus 😄 I'll jump back into the beta when there's indication that the CTD issues are resolved. 

Oh, and btw @turbomax it seems that Noel currently holds the Avsim FTV record with a value of 99.73 😄

perhaps you could repeat your CapFrameX tests one more time now using SU14? I hesitate to leave this SU15 frametime wonderland as I haven't had a crash yet, but then again I fly typically only 1/2 hour GA VR.

can't let that happen! you mean he DID hold the FTV record.🤣

99.93% @ 4K LOD/TLOD 200 - framegeneration, TAA, DX12, Cessna 172, no FSLTL etc.

 

all that at160 fps average @ 4K

REAL 4K resolution, UHDTV

 

200 fps @ 2560x1140, 160 fps @ true 4K: 3840x2160,
