Portal: Prelude RTX Can Faucet into DLSS 3 On RTX 20/30-Collection GPUs, with Not-Nice Outcomes

If you wish to benefit from NVIDIA’s newest DLSS 3 tech and its frame-generation efficiency boosting, it is advisable to have an RTX 40-series GPU and above… or do you? Might you run DLSS on, say, an RTX 20-series or 30-series GPU, and what would that appear like? Properly, it seems we now have a solution!

You really can run DLSS 3 on a GeForce RTX 20- or 30-series GPU in Portal: Prelude RTX, the brand new model of the traditional Portal mod used to showcase NVIDIA’s newest tech like DLSS, path tracing, and, after all, ray tracing. This may be completed by downloading the NVIDIA DLSS 3 Body Technology DLL (seize it for your self right here) and changing the same old DLSS DLL. A few caveats right here – solely the “1.01” model of this DLL works and it solely appears to work on Portal: Prelude RTX, no different DLSS 3 suitable titles. Why this specific loophole exists, I’m not precisely positive, however it does appear to work. You’ll be able to take a look at Portal: Prelude RTX operating on a GeForce RTX 3060, beneath.

As you possibly can see, whereas DLSS 3 on a 30-series GPU works in principle, the outcomes are very stuttery on account of poor body pacing, making the entire endeavor a little bit of a misplaced trigger. The entire level of DLSS 3 is to easy out efficiency so a bunch of stuttering type of defeats the aim. However nonetheless, it does technically work.

In fact, this simply results in an apparent line of hypothesis – is DLSS 3 being restricted to RTX 40-series playing cards simply a synthetic factor completed by NVIDIA to spice up gross sales of the newer GPUs? Is there a risk they may allow it on 20 and 30-series GPUs with a firmware replace? Or is there a extra basic {hardware} limitation that merely makes it unworkable? Hey, don’t have a look at me, I’m not an engineer. I don’t have the solutions.

What do you concentrate on this? Is there some fantasy world the place DLSS 3 on lower-spec playing cards is a factor? Or is it simply not attainable?
