I didn’t see this topic come up in the search. Are there any current plans of implementing either (or both) of these before or after launch - with both now being open source? FSR would certainly grab a wider range of cards. This may help with some of the feedback regarding performance, and would be interesting to see how well they would work in Last Epoch.
Hey, Welcome to the forums…
The ability for LE to support the FSR & DLSS functions from AMD & Nvidia will most likely depend on Unity (the game engine LE is developed in) supporting these features…
At the moment LE is using 2019.4.23f1 of Unity…
From what I can gather Unity version 2021.2 will support DLSS. So if EHG updates to the new Unity versions, then LE will/should support DLSS.
Apparently FSR will also be supported in a new upcoming Unity release (apparently its in the beta Unity - no version number available - as of July 2021)…
So… EHG will have to weigh in here regarding the possibility of upgrading to the newer Unity releases to get these features…

They’ve said they’re unlikely to upgrade to a newer version of unity unless it offers significant benefits given the amount of time/effort that would be required to update.

Thanks for that extra info… Its not as if LE is meant to be/have Cyberpunk/NewWorld level graphics… so for this kind of game, I am not entirely sure if DLSS or FSR would be enough of a motivation vs the effort required. That ball is squarely in EHGs court…
I would say if either allows folks to run the game at their desired resolution with greater performance, than that should provide at least a strong consideration towards devoting resources into such a project.
As AMD and Nvidia improve upon their perspective technology - I think most studios will start start looking implementing both where they can. This coupled with 2k-8k (higher refresh rates too) monitors becoming cheaper to produce whereas GPU’s alone probably won’t keep up.
Your comments make sense and adding this technology to any game is a no-brainer for the future.
I just wonder if EHG has the resources/time to make this change now vs doing an upgrade post 1.0. Pesonally I have zero idea of how difficult it is to upgrade Unity from a 2019 to 2021 version level - perhaps there have been substantial changes (like the scripting engines etc) that will require both time to do and perhaps even a learning curve to implement… Perhaps its easy… as I said, EHG has to make this call and realistically I dont think they can afford to delay their current timelines especially if upgrading could be months of work…
I’m not really sure but I think Mike said it would take something like two to three months. And of course, during that time, many other developments would be on hold.
Here are some relevant answers to this thread from Mike during both the dev streams or on the games Discord.
Q: Now that Nvidia has released the DLSS 2.0 SDK Free to all developers INCLUDING Unity 2021.2 beta natively supporting it, WHEN can we expect this in the game?
A: Youtube Link (from 1:33:40 to 1:34:44 of the video but it should start at the correct time)
Q: So I noticed that LE uses Unity version 2019.4.23f1 (3f4e01f1a5ec) - why such an old version, would migrating to the newer version be ideal?

Q: Has there been an enemy type or environment that you wanted to add to the game but were limited because of the version of Unity you’re using? (I had to improvise with the question because it wasn’t fully read)
A: Youtube Link (from 23:28 to 25:05 of the video)
Follow-up Q: No performance gains over a two year updated engine? Seems like there’s been a bunch of changes looking at their changelog, but then again I’m not a developer so I don’t know.
A: Youtube Link (from 28:02 to 29:30 of the video)
TLDR/W: Both FidelityFX & DLSS technologies currently require an upgrade to the High Definition Render Pipeline (HDRP) as well as the version of Unity. As @vapourfire, @Llama8, and @Shtrak have already mentioned above, these changes could take months to implement and would put many aspects of the game on hold during that time. This doesn’t mean that these changes will never occur, but rather that they are not planned at this time.
