DLSS not doing anything

[XOLiD]

Unlike in other games I've played where turning on DLSS gives a noticeable FPS boost even on quality mode, using it in MSFS doesn't improve my FPS at all over TAA and just makes everything slightly blurred. Even changing to ultra performance shows no FPS boost, wtf?

I was getting an FPS improvement with it in DX11 - were you in DX11 or DX12?

But the image quality degradation (on Quality setting) in the cockpit was not good enough for me to think the extra frames were worth it.

All this might very well change next week when the driver is released. So we all just need to be patient for a few more days.

I use DX11 with DLSS on PERFORMANCE. The 777 can also get 40fps and is smooth as hell. Pity this has a poor VR COCKPIT ZOOM which will likely never get fixed.
I also sharpened to CAS 200 which rid some of the Stutter it first had. My settings are almost Maxed out completely.
The 787 gets a nice 43fps.

You can try the new nvidia non-game drivers. The game ready drivers don't have the now added improvements they talked about in the live stream a few days ago. They said we would have to wait for the new drivers that should be released by mid November. Someone elsewhere said the latest just released non-game driver already has the code, but i have not tried it yet so I can't confirm. On my 3060 I don't see improvement in FPS with this latest update 10 (as promised by nvidia) but they were very clear the driver was not ready yet in the next sentence. Others on other forums are reporting the same as you and I. I would wait until the next driver release before being concerned, but then again I wouldn't hold my breath either.

The game uses dozens of threads. And at some point you are going to hit a limiting factor - be it on the GPU or the CPU.

Regarding your comment about the game being un-optimised for DLSS, we don't even have the driver from Nvidia yet. Maybe we should wait until we get the new driver before wrongly assuming that a limited CPU means the game is un-optimised. XD

While looking at task manager or resource monitor, I can see one of my threads maxing out quite often, while the other 15 are sitting at around 30-40% usage. Sadly my GPU usage never really goes above 70%

Also I am using the latest driver version 517.40

Yeah - pretty common. I'm in much the same boat here. The main thread is limiting me. But don't think that's because it only uses one thread. Open up Resource Monitor and you can find a count of the threads each application has running. Flight Sim on my machine is usually above 120 threads. But, of course, one of them is going to be a limiting factor CPU wise - and overall for the application if you are limited by the CPU overall. (like you and me).

I'm not saying they couldn't do better. But it's a long shot to claim something like that without being privy to the source code. Because, at some point, there is going to be something that limits the performance. And, as Rever said, flight sims are pretty compute intensive, so it's common for the CPU to be the limiting factor, particularly with the power of GPU's these days.

Disable Photogrammetry and all AI. Reduce Terrain LOD to 100 or less.

In the past I have used Process Lasso. It controls which CPU software can run on. I used it to force windows to one cpu and the P3D or XP threads to run on any other. It did help.

I have no idea how much it would help with MSFS. They do have a free demo version.

My config i9 9900k + 3080ti + 32Go ram + SSD
Unfortunately, nothing change for me I have better performances with TAA at 3440x1440 instead of DLSS (from performance to quality mode). I don't don't understand. I tried Dx11 and Dx12. Dx11 is better for me. DLSS just does lower my FPS. I loose 10-15% in comparaison to DX11 + TAA..

As already mentioned in this thread (including the solution) the problem is your CPU at these settings. Turn on the developer mode and you'll see you're main thread limited because the game is hammering one core of your i9 9900k in the game's current form. Flight Sim is very cpu intensive (a 12900k can also get swamped) DLSS is making your 3080Ti do less work but it's not helpful if your CPU was already at the limit. Quality to performance is asking the GPU to do even less so of course that won't help either.

So lower cpu related setting like suggested above by Manwith noname and with the performance metrics with developer mode on you'll see the limited my main thread get replaced with a gpu limitation and that's what you want. You can also increase other setting that tax the gpu. DLSS will give you more performance once you are gpu limited.
This can change depending where you are in game, as the further away from the ground or over ocean and fields will be less cpu intensive than over a city or on the ground of course so play with the settings until you get a good balance.

DLSS 3.0 will apparently help in cpu limited scenarios as well as gpu which will be interesting to see but that's only for the upcoming RTX 4000 series of cards sadly.

Its true! I have a 12900H and its always the true limit! Meanwhile in DX12 it gets better because of this reason!

But after all the experience I try to get an ne DDR5 System, new CPU and especially the RTX4090 to relieve the CPU because DLSS 3.0 CPU-Bypass Features!

It does nothing for me at the moment aside from blurred instruments and occasional temporal artifacts around moving parts.

12900k sits at 40% while playing, both 3090 at ~50%.

You are cpu limited as explained multiple times in this thread. Your low overall usage doesn't mean anything unless all cores are taxed equally, which is certainly not the case here. Check individual cores. 1 of them will be maxed. If it wasn't your gpu usage wouldn't be so low.

Exactly. Especially in DX11 is Singlecore limitated! So see many load cores but one of them is overloaded!

DX12 and later RTX4000series will help... its no coincidence that Nvidia and Asobo implement a CPU-Bypass Feature for FS2020!

FS2020 is the new reference Game for RTX4000 series and Nvidia! So we get hardcore features... for this hardcore simulation... but we all need new hardware soon!!!! Very soon! Trust me!

Its a turning point in history now! The free lunch is over! DLSS 2.x is Technological dead end for now!

Yes DLSS 3.0 does look very interesting. I'm hoping the 4070 or even a 4060Ti are nicely priced. I may upgrade without skipping a gen, which I rarely do. Exciting times ahead for gaming imo.

I'll ask the obvious question.

What resolution are you running at??
If your're running at 1080p then it will make zero difference with your rig, as it will already be cpu limited.
Try increasing the render scale to maximum, other options to maximum, and then try dlss.
Having said that, there really isn't any point because if you increase your render scale, then use dlss, it's just rendering at a lower resolution anyway.

I run in 4k, with a 2080ti and a Ryzen 5 5600x, plus 32gb ddr4 3200 ram, installed on an nvme m2 ssd drive and dlss makes a difference to me :)

If you already posted your resolution and I missed it, then accept my apologies :)
