DLSS 4

[Habu_69]

Tx. Does DLSS-FG (frame generation) provide any benefit to DCS if not using an RTX 50 card?

Well somewhere between page 1 and 7, i got confused.

Are you talking about these two changes is the profile inspector?:

 

Ok, same here.....
Got lost and confused throughout further reading
So how is the latest instruction?

What I got so far:

NVidia Inspector (I assume latest version)

Latest DLL files? where to download and how can I recognize the latest version? And where to put them?

No DLLswapper required (with the new Inspector)

Geeezzzz: That is getting more confusing every time.

Anyone here with a simple instruction for dummies like me?

Cheers!

For DCS you need just the NVIdia Profile Inspector + latest drivers (Nvidia App will do this for you).

NVidia Profile Inspector as instructed in video enables this swapping to occur by default each time game tries to use DLSS. You will not need to run this tool later - no magic here, it is just re-configuring the driver.

Do not copy any files over, if you just enable the settings as stated in Video the replacement will occur automatically for any game and you will not break integrity check in DCS.

DLSS itself will be activated only if you enabled it in DCS.

You have a very easy step by step guide here

THX! I will give it a shot. Never thought it was that simple tbh.
Will report back!

Thx for that! But on GitHub it wants me to download the DLL files and install them seperatly. So I guess I will skip this method. Btw, the GH thread is more than 20 days.

Cheers!

The poster updates the thread on a regular basis

 

[EvilBert VR]

Ok, that makes me confused again.

1st method does not demand to manually install DLL files into the folders

2nd method (Esac_mirmidon) requires to download and install "NEW" DLL files manually into the .bin folders of DCS. Is there a difference?

And btw: What are the settings I need to activate in Inspector in order to get those things running?

Geeez... I feel like a complete NOOB atm.

[EvilBert VR]

So far, what I've done:

Latest Nvidia driver (572.16)

Latest Inspector (2.4.0.11)

Picked "DCS.exe" in Inspector

NOW: What to click/ activate in Inspector (I assume) before starting DCS?

Cheers

After repeated testing (about 12 hours) I still think that DLSS 4 (310.2 preset J and K) is deficient in several areas. 

• Spotting is very blurred.
• There is still some smearing around the edges of planes like "leaking oil".
• Severe (and unplayable) ghosting against ground textures. 
• Loss of contrast of planes against clouds in some situations so they "disappear".
• Performance (in VR with QVFR) of DLSS at performance setting is similar to MSAAx2. There is very little benefit of SS with DFR (subjective opinion). 

To qualify my experience most of my testing is done with WW2 aircraft and settings. I have also tried increasing the centre resolution up to equivalent of 4500 pixels to try and offset any artifacts. No difference. 

Is anyone else seeing this?

I had the exact same experience. I did find that lowering my PD from 1.3 to 1.0 offset the performance loss somewhat while still maintaining clarity. The ghosting on other aircraft was a deal breaker for me though.

I've tried lots of variations to try and offset the artifacts but nothing works.

Using Quest Pro (max resolution), Quad Views with focus resolution 1.8/ peripheral 0.2, DLSS/Performance and preset J, I can concur to the following:

• There is still some smearing around the edges of planes like "leaking oil".
• Loss of contrast of planes against clouds or ground (not at all times though)

On the other side performance has been exceptional and clarity is comparable now to 2D

Thought I had to pick a profile somewhere as well?

That's what it does. Picks the latest one

Ok, Thx.
So no need to preset J or K or anything like this?

I can't seem to pick DCS.exe in the Inspector, I type "dcs" but nothing appears. I tried Digital Combat Simulator: Black Shark but then my options look very different to the screenshots people have put in the recent posts.. grateful for any ideas?

J and K are both available in the dropdown so you can select J if you like. Latest just defaults to K currently.

DCS.exe doesn't show for me either, like you said it's the Black Shark one. You can just use _GLOBAL and will apply to everything. Check if you're on the latest 2.4.0.11 release. I believe in previous releases these options were DLSS-SR Override and DLSS-SR Preset (0x000FFFF is latest and 0x000000A is J if it gives you hex values). It may still appear like that.

I definitely have the latest 2.4.0.11 but I still get these options:
Enable DLSS-FG override
Enable DLSS-RR override
Enable DLSS-SR override
Not sure why that is, or what these 3 refer to but I will do as you suggested.

the original frame generation (i.e. x2 only) is supported by 40 series (and up I suppose), the new dlss 4 multi frame generation (x2, x3 or x4) is 50 series only.  But neither FG tech is usable in DCS VR (or any VR title) as I understand it (and I assume this is what you mean since this is the VR forum).  I have no idea if it can be made to work in 2D DCS.

After many hours of perseverance I am now very happy with DLSS4. Yes, there are some downsides but the positives definitely outweigh the negatives. The clarity and AA is so good that I have been able to reduce the size of the foveated region (QVFR) which has really helped performance. 

For anyone interested:

DLSS4 3.10.2 preset K

VD Godlike at 72 Hz

QVFR centre 0.2x0.2 at 1.4; periphery 0.38. Sharpness 0.9. 

(The boost in the foveated resolution combined with increased sharpening has reduced ghosting and improved spotting) 

Given that this is early days for DLSS4 the future looks promising

[VR Flight Guy in PJ Pants]

I recently went back to MSAA x2 and may be, just may, I am giving this a shot once again.

[Fiztex]

I can't imagine flying with MSAA again after getting Quest 3 with Godlike VD 80 Hz to work with DLAA J/K profile. Minimal smearing against the ground is nothing to me compared to the benefits in performance and visuals I'm getting in return.

This is very situational and is quite bad in some conditions. However, I agree that overall this is offset by significant benefits.
