FSR vs DLSS

[GoranM 3,256]

There seems to be some misinformation posted in various threads about DLSS, and games/flight sims that some people think, need it.  Posts made by people who don't really know what FSR and DLSS does.  Particularly people who think X-Plane needs DLSS, and if it doesn't use it, it's obsolete.  As a matter of fact, FSR is far more important in moving forward, due to it's advancements and compatibility with both AMD and nvidia GPU's.  

As the article states:

If you have access to DLSS, you should use it. The days of buying an Nvidia GPU specifically for DLSS are over, though. With FSR 2.0’s impressive image quality, you can still access high-quality supersampling regardless of which brand you have in your gaming PC.

Unless nvidia make DLSS cross compatible, FSR is obviously the way of the future, and it'll be in the competitions best interests to adopt a more flexible upscaler.  If not, it will be left behind.

Here is the article that shows, in basic terms, what FSR and DLSS are, and what they do.  Contrary to some peoples opinion, they do not magically turbo charge your GPU to give better fps.

Thanks for the link, it gets rid of many of the misconceptions we often read in these forums by uninformed/biased people.

So, FSR2.0 has basically the same image quality and performance of DLSS, but has vastly more compatibility in terms of GPUs. I think it was a no-brainer for LR to go the FSR route, definitely the right choice. Looking forward to FSR2.0 in future X-Plane updates.

I don't really use super-sampling. What I miss on XP is Nvidia's frame generation that I have on MSFS and that basically doubles my fps. I heard that this is coming to FSR eventually...

Whatever comes to FSR, you can count on LR to make an update that will exploit it.  I didn't really know much about FSR prior to getting selected for XP12 testing.  Once I saw it in the settings, I did some research, and realized it wasn't as obsolete as some people thought.  

Personally, and this is just personal preference, if I get 30-40+ fps in XP, I'm happy.  I see some people get excited about 100+fps.  I never understood the excitement.  But to each their own.

AFAICT

FSR / DLSS only really matter if you are running an 8K display or need extra GPU headroom for high FPS in a very high res VR headset.

FSR 1.0 is already going to "pretty much" do the job there - better than running 4K on an 8K display.

FSR2.x is - right now - the only way you can get full 8K out of the current GPUs.

There is some potential benefit to be had if you are on a >7 year old GPU on lower resolutions, but the only reason games are doing that is so they can get close to acceptable performance for new games on >7 year old consoles (aka the xbox one).

NV does a good job at breaking new ground, but the open source way of doing things wins in the long run. A great example of this is to go to newegg (because of their search capabilities) and filter gaming monitors for Freesync (AMD) vs. Gsync (NV) capability. I count 7 pages for the first and 2 for the second. 

The same thing will happen with upscaling/fake frames: NV was first and AMD wins in the long run. Given that FSR2 is on par with DLSS2, it's only a matter of time before FSR dominates.

One could see current GPU market share as a reason to not care, but when considering other OSes and the fact that Intel could really crack the market if they wanted to, multi-hardware/platform is a no-brainer.

So XP12 will for sure get an update to it's anti aliasing? It currently leaves a LOT to be desired.

For not it seems to be completely disabled.

It doesn't but it's in the "good enough category"

LR needs to implement a proper motion vectoring to get TAA/FSR 2.0 or DLSS working with their engine. Once they do. yes they should implement all of the upscaling technic they can to reach the most amount of users

less people are using 4k and 8k displays than VR, its seems the bigger complaints are coming from people with 2+ decade old 720p displays (1998) not being happy with the anti aliasing 🤷‍♂️.

I'm running a 4K monitor and AA is not working as it does in every other sim I use. 🤷‍♂️

AA does nothing on a 4k monitor.

I use a 1080p display and AA is basically disabled

All AA does is turn

into

And thats zoomed in multiple times so you can actually see it.

AA affects single pixels, by the time you hit 2K/1080p single pixels are so small you are lucky if you can see them, 4K/8K monitors you'll need a microscope to see the difference.
