DLSS 3 Magic: Portal: Prelude RTX on 20/30-Series GPUs

Portal: Prelude RTX Can Use DLSS 3 on 20/30-Series GPUs, but Maybe Well

If you want to take use of NVIDIA’s most current DLSS 3 technology and the speed gain it gives for frame creation… or if you don’t, you’ll need a graphics processing unit (GPU) from the RTX 40-series or above. Is it feasible to utilize DLSS on a GPU from, for example, the RTX 20-series or the RTX 30-series, and if it is, what kind of results can we expect to get from it? It would seem that we are in possession of a remedy for this issue!

In the updated edition of the popular Portal game known as Portal: Prelude RTX, Direct Linear Super Sampling 3 (DLSS 3) may really be played on a GeForce RTX 20- or 30-series GPU. This mod’s purpose is to showcase NVIDIA’s newest technologies, including Direct Line Source Shading (DLSS), Route Tracing, and Ray Tracing, of course.

It is possible to achieve this objective by simply replacing the conventional DLSS DLL with the NVIDIA DLSS 3 Frame Generation DLL, which can be obtained by downloading the appropriate file from the link provided above. Before we get started, a few caveats and disclaimers: The only version of this DLL that is supported is the “1.01” version, and it does not seem to work with any other DLSS 3 compatible games than Portal: Prelude RTX.

Although he has not quite sure on the rationale for the existence of this particular loophole, it does seem to be effective. In the video that can be seen below, you will be able to observe Portal: Prelude RTX being played on a GeForce RTX 3060 graphics card.

As can be shown, although it is theoretically feasible to run DLSS 3 on a GPU in the 30-series, the actual results are extremely choppy due to poor frame timing, which renders the whole project somewhat of a fruitless venture. A substantial amount of stuttering works against the objective of DLSS 3, which is to increase performance, and is thus counterproductive since it works against this objective. On the other hand, it is feasible from a pragmatic point of view.

Naturally, this simply leads to a natural line of hypothesis, which is the question of whether or not the restriction of DLSS 3 to cards in the RTX 40-series is merely an artificial item done by NVIDIA to boost sales of the more current GPUs. Naturally, this just leads to a natural line of supposition.

Is there a possibility that, if they upgrade the GPUs’ firmware, it will be feasible for them to turn it on with the 20- and 30-series graphics processing units? Or, is there an issue with the technology that is more fundamental and just prevents it from being implemented as intended? It is not worth your time to look at me since he is not even a licensed engineer. He is unable to provide accurate responses to the queries.

In regard to this topic, what are your thoughts? Is there any alternative reality where Directed Least Significant Surfaces 3 might be implemented on cards that have lower specifications? Or is it the case that doing so is just not possible?
