Official DLSS Beta - Show Off Your Results & Call For Feedback

The HDRP Render Debug view doesn't work correctly when using DLSS

I set forced resolution to 50% (quality didn't matter)

All the debug views seems to be of limited to half of the screen instead of scaling up(zoom in, you can see less than half of screen shows the debug info):


In the scene view, the debug view worked for some time after going gray and showing this error:




Disabling debug view didn't fix this issue either, I had to restart unity or enter play mode (Domain reloading and scene reloading was enabled) to fix this (game view also went black)

 

As for me i tested it since the 2021.2.0b6.
I use DLSS as an AA (Anti-Aliasing), the quality is great especially in 8k UHD.
Here's the video link: https://www.youtube.com/watch?v=--kT0k2iEUc

About using DLSS with RayTracing, In build it is great
but in Editor (Scene and Game view are visible) , it is slow.
I hope there is an option to choose to make it work in Game View only.

 

My internet is a bit slow to submit the whole project in bug report so I've uploaded a video showing the error and how to recreate them:

I have uploaded the package manifest file and package lock file.

 

DLSS has stopped working for me. In 2021.2.0b4 I had it working pretty and fast.
I have 2 GPU's in my system:
1080Ti (Primary)
2070 Super (Secondary)

When DLSS was working, my 2070 was the primary GPU. I swopped them a while back so the 2070 is the secondary. Now I dont know if it hasn't worked since then, as its also been few weeks since I looked at the project.

It was working few weeks back, but I'm now greeted with this:


Could the issue be simple because I swopped my GPU's around, or is there something else I should be looking at?
(NVidia Studio Driver 471.11)

DLSS is now not working for me in neither 2021.2.0b4 nor the latest 2021.2.0b11...

 

Hmmm weird it doesnt list my 2070 Super:


Even though device manager sees it and reports its working fine:

 

Hi,
"Rendering both Scene and GameView with raytracing which is too slow." plus DLSS turned on,
but it seem the performance on the Unity 2021.2b11 is now better,
both scene and game view are visible with raytracing and DLSS turned on.
It is even better if the resolution of the Game View is low res.

Video:

This might be a request, is it possible to add an option to only render ray tracing and DLSS in game view only?

 

Its working again now
I swopped my GPUs around again so my strongest GPU is now the primary and I installed the latest NVidia Studio Driver

 

Hi,
Ah now i see, it means disable it on the HDRP Global Settings (This is global) and only render it on a camera (Game View).

DLSS only applied to Game View already?
Because previous beta, it also applied to scene view.

Thank you so much for the reply and info.

 

We just enabled this but there seems to be a problem with the compositor because our main camera now appears cropped to a quarter of the screen in the bottom left corner. Have you had any issues like this?

 

Great- we discovered that it is connected to the quality settings on the asset/camera - if we put it on Ultra Performance it is fine, but if we choose higher and higher qualities it progressively crops the main camera view smaller each time. Hope that helps!

 

So an update from us - we managed to get our application working fine using Ultra performance - but actually we found that there was quite a substantial drop in performance when DLSS was enabled. So we have turned it off again. It would be really interesting to know in what circumstances you have noticed DLSS actually being detrimental to performance.

 

One more thing I Happened to notice was that the dithering pattern also get bigger with dynamic resolution (which is to be expected I guess), but is there a way to mitigate this because it's really noticeable at some distances.

Here's and example:
DLSS off:

DLSS on:

 

Is there any update on DLSS and the compositor? I just tried beta 14 and there was no improvement at the moment.

 

Is there a way to do this inside shader graph? (also, what if the screen size isn't forced)

 

So hard to do this - we are on a very large project - actually it seems the compositor is working now - but the performance drop is a real shame. It is actually considerably slower with DLSS that without on all modes.

 

I want to make sure I'm actually using DLSS correctly, as another user's question over on the FSR thread, prompted me to question the way I'm using it!

So as far I understand, it upscales things. But that is as far as my understanding goes. I simply install DLSS by clicking the "Fix" button in my HDRP Asset, (and I dont touch the screen percentage setting at all)

Then on my camera, I enable Dynamic Res, and set DLSS to Ultra performance

My game view is set to 4K.

So then, where does the "dynamic" part of all this come in then? If my game view is 4K, does DLSS upscale it to 8K for better sampling and then the game view uses that info to just display my stuff at 4K?

.....or am I suppose to be doing something with the screen percentage settings etc?

 

See my reply here: https://forum.unity.com/threads/amd...iew-now-available.1141495/page-2#post-7567978

everything I said there applies to DLSS, and all other upscale filters.
'Dynamic" refers to scaling the screen% (goes from 10-100%) as required to achieve your FPS goal. The lower the screen % is, the bigger the performance gain on the GPU. Rather than setting it manually to a particular screen%.
Min/Max exists to help you with that. Min being the least amount it's allowed to go to when trying to achieve the budget you set, max the opposite.
If you want the 'dynamic' part of it though, you'll have to do the GPU timings yourself. It's not built-in.
Otherwise, you tick forceScreen% and set a value.

 

Ah well in that case, all the fuss is pretty useless for me as we're using Unity to render offline and any screen percentage lower than 100% just lowers the image quality.

That being said, DLSS is not totally useless for us, as with screen percentage on 100%, or not even using forced screen percentage, the AA that DLSS gives us is miles ahead of anything we get with TAA. So in that sense we're purely using DLSS for AA

 

Update: issue fixed by recreating HDRPDefaultResources

I'm getting this error every frame if I turn on DLSS when SSR is not also enabled.

Update: issue fixed by recreating HDRPDefaultResources

There is another error when raytracing is enabled:

RTHandle was created using a regular Texture and is used as a RenderTexture
UnityEngine.GUIUtilityrocessEvent (int,intptr,bool&)

 

I found one more issue with AA when using DLSS:

You can see the jagged edges of the rectangle on the plane, the rectangles are procedurally created using shaderGraph:


Is there a way to fix this?
These are my camera settings:

 

Also having this issue

 

I managed to fix my issue by recreating the HDRPDefaultResources folder. The one in my project was created several versions back and maybe something is no longer compatible.

Basically I removed that folder and used the HDRP wizzard to recreate it. Everything works fine now.
