DLSS 5 leaked through an early-access build of NBA 2K27 last week, and since then, the modding community has been hard at work patching it into all sorts of different games. Modders on the RenoDX Discord have now pushed it into RTX 30-series "Ampere" GPUs, despite this generation having no official support for DLSS 5. The results, however, are less than stellar. On the RenoDX Discord, a user with an RTX 3070 laptop GPU running Kingdom Come: Deliverance II saw render latency jump from roughly 29 ms to over 3,300 ms with Neural Rendering enabled, resulting in well under 1 FPS.

Over on X, user @Flourek got it running on an RTX 3080, and it fared little better. It too, however, dropped from around 130 FPS to just 4 FPS in Deep Rock Galactic, while RTX 3050 and RTX 3060 Ti cards reportedly hovered near 1 FPS across Control, FiveM, and Kingdom Come: Deliverance II. Just a couple of days ago, modders got DLSS 5 running on RTX 40-series "Ada Lovelace" cards, and performance held up noticeably better. As we noted in our DLSS-NR deep dive, Ampere lacks native FP8 support, which the leaked DLSS 5 model apparently relies on, so the steep drop isn't surprising.

Officially, DLSS 5 only supports RTX 50-series "Blackwell" GPUs, and there's no word about whether NVIDIA even plans to add support for RTX 40-series cards, let alone older ones.
