NvRTX and DLSS 3 for 5.1

Hey Team, hoping you could provide some background around the timing of your effort with Unreal 5.1 and when we may see the NvRtX package built/available on your GitHub. In addition, does your team intend to bake DLSS 3 into this package as well, and, if not, when may that be available for more public consumption? Our company has filled out the early access DLSS 3 forms but have not heard back, so we’d love some info on GA.

I chose to post this question today because Nvidia is out marketing these features, but as far as us devs can see, it’s not actually available. An update from the Nvidia team to the developers would be welcomed.


Hello @draughn101 and welcome to the NVIDIA developer forums.

The DLSS update for Unreal engine 5.1 is nearly done, our engineers are busy updating the software, even if we cannot share a fixed ETA yet. We will announce it here and on the DLSS pages as soon as it is done and well tested.

DLSS 3 is a greatly different piece of software and general integration into UE (or other tools) will take more time. The reason you see it already in a lot of games is that we have engineers out with those development studios helping them directly since the interest and demand is so high. This is parallel to the work on general availability. I just have to ask for your patience until you receive notification regarding DLSS 3 news.

For NvRTX tools like RTXGI the current release supports Unreal Engine v4.27 and v5.0.
As of UE5.1, Epic has enhanced the quality and performance of their Lumen GI solution which provides a viable GI option for most developers. We feel it’s valuable for our customers to work on optimizing Lumen on Nvidia GPUs to ensure it remains the best place to achieve the highest graphical experience possible.

I hope this helps!

Hey Markus! Can we expect the same shorter timeframe for NvRTX or should we expect the longer timeframe like with DLSS 3? I would love to test out what’s described in that blog post. Thanks!

Hello @sce48 and welcome to the NVIDIA developer forums!

If you are talking about RTXGI then the wait will be at least as long as DLSS 3 or even longer I am afraid. As I mentioned above the advancements of Lumen in this area are great and NVIDIA is likely to give the built-in functionality their full support than continue developing a parallel solution.

I hope that answers your question.
