(NDU registry change) Increase performance immediately! AMAZING!

I won’t argue, but definitively won’t agree either, why?
…I am above computer user average (in my environment) as many in here are. I built my last computer 20 days ago (ROG Strix Z960-F, 12900KF, RTX3090, 64GB DDR5 5200, M.2 1TB, water cooled, some aditional sata SSDs, no OC yet, all in all, something I would define as a pretty decent rig…). I manage all at ultra, and depending on scenery (and I always use AIG TC with traffic at 99%), sometimes very smooth, but not that good in EGLL for instace (aout 20-25), but hey! all @ultra. Today I have been messing around on a couple of hours flight with the a320 FBW (experimental) super-overcasted sky by the way. I took of and kept at the beginning of the flight a good 48-56 fps consistent. Out of the blue, it started to go down, eventually reaching 19-22!!! What is going on!? the reduction of performance so many people talk about…? So I did this (well something before this as well but it didn’t had an effect though): in flight, went to settings and move terrain level of detail to the far left of the slide, save, back to flight, external view, give at least 30 secs or more to stabilize, move around the view, up and down, and obviously, fps went up. Go back to settings and now move to max (far right of the slide) and repeat the process. Fps went down, obviously, but well above the 19-22!!. Now, for third and last time, I repeated the process and set Terrain level of detail @250, which is what it was at the beginning of the flight and the value at which I started the process: while typing I’m start flying @ 42 fps solid, and since then, it has started to drop again… The important thing here, I think, is that it recovered, despite going back to the drop, but somehow, it recovered.
Please others, try and post back, lets see if this is replicable. If it is, I hope people with more knowledge than me may start to figure out (to me, this is as far as can go, but definitively is something to do with some “data accumulation” or the sort).

By the way, I haven’t tried the register tip yet, my point is that my drivers are the most updated ones in the ASUS website, can’t be the problem, is just 20 days ago.

my experiance: Tlod 250 is for most cpu’s to much.

Within these topic Link we determined that the fps goes up/down depend on the regions you fly over ( whats on ground ) and this depends on tLOD where 250 is a very high value. In my tests I had can exactly reproduce in long flights that fps goes up and down and come allways back to normal if I reach no-cpu-intensive regions ( as which reason ever these are more cpu intensive )).

And.. this will also not changed with disabling the ndu :slight_smile:

How can you say is too much (or too low)? It will be too much or too little depending on your rig. Before I change the computer, I was running a mega optimized 14 years old one, and I had to run it at 25, in optimum conditions at 50… obviously for that rig 250 is too much… Try to be clear please, free statements won’t help me, just put them with a bit of underpin info, at least a bit: too much, too little, great, bad… with nothing else to sustain it, doesn’t help much. Since I posted the above, I have repeated the process (just for curiosity, fps where not bad 45s so nowhere near the first drop to 19-22,… and I flying over the sea toward the Netherlands (I have Denmark in sight at my left) and fps are 50-53 solid… I’m saying it because the area where you fly, as you mention, may have an impact, so I support that.
However the come back on performance was in the same area of the drop, so still is intriguing.
By the way, I made quite a bit of test to reach 250, and is definitively my limit, going to 255 already has a noticeable impact.

I use 250 as well, it’s the best compromise for me with a 5900x.

However, whatever your CPU is doing at the moment is nothing to do with this NDU fairytale, which is what this thread is about after all.

ps That sounds like a killer machine, an altogether more interesting subject! :wink:

… and I tell you, a hell to get the parts during the COVID time, I started before Christmas! But yes, I’m thrilled with it, thanks :blush: (I’ll see if in a few months I start to understand the new UEFI bios, is new territory for me, and see if OC helps a bit)
You may be right, its not exactly related to this, although I reached it googling for drop performance in long flights…

its a language exactness thing , I’am just not native english speaker and may be in general is my english worst :rofl::slight_smile:

I can also set in lots of regions more than 250, but if the scenery becomes little bit more complex the one-core-limit is just hard and the single-core-performance is that what it limits. In lots of topics is currently these max of 250, better 230 for most cpus mentioned if you come into complex sceneries. You can read all these topics if you mean I write things without sustance :rofl:

The main point I wanted to mentioned was: the region and the dependency to tLod and that we discussed that in the mentioned topic ( and a lot others ).
Here is the topic more the NDU setting.

PS.: and I have to say I’am a bit envious to your system :grin:

No worries, I’m not going on as this is not meant to be a chat :wink:, But I didn’t mean you write with no substance, just the reply to me, because I was looking for understanding, hence I needed a bit more precision, but I got it eventually. As I said, lets not kidnap the thread because I see, our chat is definitively not related, but it would have been a really interesting talk anyway.
Cheers :slightly_smiling_face:

Wow!
Now following the instructions in this video (I think someone has already linked it somewhere in this formum) gave me 15% increase and solved my jitters.

I’d try this before screwing around with anything else!

I also see nowhere in that video somewhat about NDU :rofl:

I can only recommend what I already wrote: be carefully with all these click-bait-best-performance-youtube-videos. This one is again such a kind… For DDU, etc. we have other topics in forum - also these one where some users killed here windows installtion with that tools and only for alleged 3fps more.

The thing that does my head in with these posts is that people make these grandiose statements without a shred of evidence to back it up other than their anecdotal opinion. Saying that this change has given you 15% better performance is meaningless. How are you quantifying that?

As a number of us keep saying on various threads, unless you are testing the 2 configurations with the exact same scenario (time of day, aircraft, position, weather, traffic, same server with the same ping etc etc) then it’s impossible to draw any proper conclusion, let alone make statements like ‘wow, this is the fix of my dreams’.

I saw Overkill Simulations put up another clickbait type video espousing this magic driver fix linking to that video. One of his conclusions was that he could now fly over New York which he couldn’t do before. After waxing lyrical about this magic fix he then let slip that he’d turned down his TerrainLOD as recommended in the second video. Well duh! There’s your performance improvement right there, I’m afraid it really is that simple.

Exactly right. These videos are all about the monetization.

I tested the before & after FPS at the same locations, at midday, in the JF Arrow and with the clear weather preset, no live, ai or mulitplayer traffic using the same current nVidia driver version.

My average Before and After FPS results were:
Sitting on runway 35L YMMB set for take off: 46 > 53
Flying at 1500 feet over Melbourne city center on a direct route between YMMB and YMEN: 51 > 58
Parked at bay 24 YMEN before shut down: 39 > 46
Flying at 3000 ft between YMEN and YCEM air field: 54 > 68

So it might sound grandiose but I tested thoroughly enough for me to confidently say that on my system, overall it was around 15% better.

Note that previously I had always installed the full nVidia driver installation including GForce experience installed.

So I don’t know if doing this thorough nVidia driver clean and minimal install will help everyone as it will depend on how “bloated” your current nVidia installation is but it’s one possible fix that’s worth trying especially if you are running an older system like mine where I’ve done muliple driver updates over the last 2 years.

Note the MDU “fix” made no difference for me either, like you I couldn’t imagine why it would. However it was easy to try so I tried it.

That’s a quantifiable improvement for sure. I wonder how much of it was the reduction in Nvidia add-ons, and how much of it was down to doing a DDU removal of the previous drivers?

If you’re anything like me I think prior to trying this I’d maybe used DDU once in 2 years, so all my GPU driver installs were over the top of the previous one.

465

Good questions

I’ve never done a DDU removal of previous drivers BUT I’ve always clicked the “Perform Clean Install” option so I had assumed that was the same as doing a DDU removal…obviously not.

I remember doing the same sort of test when I installed the Gforce Experience software because I wanted to use the their colour correction thingy. That didn’t cost me any extra frame rates then so my “bloat” happened before that!

I’m tempted to do a full normal reinstall of the nVidia drivers to see if I can reproduce the problem (I miss the colour corrrection) but just don’t have the time atm

That sounds exactly like what Overkill would do. Always first with latest (fake) news, but at the cost of accuracy.:roll_eyes:

He’s been on my ignore list for a long time.

It has been fun reading your posts debunking this whole thread.

It does look like it is a placebo. No help, no harm. And a placebo margin of error worth of folks who claim to see improvement.

If this worked as claimed. We would have plenty of repeatable evidence in this thread (like all the other threads in here, folks tend to post their numbers) but very little has been presented, and none that is what I consider to be conclusive.

Be wary, especially of long haulers, who claim something is fixed after just one test flight.

We all know this sim seems to have moods and it performs better on some days than others. Servers and our own internet connection are the cause of many issues, too. So we can sometimes try and fix an issue that is really not fixable from our end. And this particular fix helps nothing… but it harms nothing either, so it is a perfect candidate for a placebo effect.

Hi there,

This fix sadly did not work. I have tried the following:

  • NDU fix
  • Reinstalling the sim (twice)
  • Using vanilla game (no mods)
  • Reinstalling GPU drivers
  • Messing around in NVIDIA settings for hours
  • A ■■■■■■■ windows reinstall nothing works
    Is it really just broken in this update or something.

And it happened within a day too. Worked fine on a flight two days ago, launched it the day after and this issue occurs

My specs are RTX 3090, 5900X and 32GB 3200mhz RAM

Happens at around FL250, FL270 and all the way above.

What happens? You described what you tried, but not what you were trying to fix.
