nVidia has confirmed that DLSS Frame Generation does not work on RTX 20/30 GPUs in Portal Prelude RTX, despite some claims made by users. The game tech demo, which introduced RTX enhancements to the original 2008 game, has been available since July. Gamers quickly began experimenting with its settings and discovered a possible activation of Frame Generation technology on older-generation Graphics Cards.
This finding could have been if NVIDIA had been withholding such a valuable capability from gamers. However, NVIDIA clarified from the beginning that this technology might work on older GPUs but might not deliver an optimal experience, so they chose not to enable it.
In Portal Prelude RTX, the observed frame generation does not rely on Optical Flow Frame Generation but instead provides a raw output of new frames. NVIDIA has addressed this issue with an FAQ, providing guidance on how to verify if this is indeed the case. The game will produce errors when using NVIDIA Remix tools, indicating the absence of frame generation involvement.
So why does it appear that DLSS Frame Generation works on RTX 20 and 30 series GPUs in Portal Prelude RTX? According to NVIDIA, some members of the PC gaming community encountered a bug in an old DLSS DLL that falsely generates frames on these hardware. However, there is no actual DLSS Frame Generation happening; it’s just a duplication of existing frames. Frame counters may show a higher FPS, but there is no improvement in smoothness or experience. This can be verified using tools like NVIDIA ICAT or by viewing the error message in the Remix logs.
NVIDIA has since fixed this bug in the DLSS frame generation DLLs and will release an update to RTX Remix to prevent further confusion when frame generation behaves incorrectly.
In summary, while new frames are being produced (technically qualifying as frame generation), it’s important to understand that these frames do not benefit from NVIDIA’s DLSS technology. Therefore, they do not provide the level of smoothness and performance that NVIDIA actively promotes.
NVIDIA has addressed and resolved the bug, but an update to the game files is still necessary to prevent this issue from recurring and causing confusion among gamers. It is somewhat disappointing that NVIDIA did not advocate for enabling this technology, even at a reduced scale, for older GPUs, especially considering the recent launch of FSR3.
