> But the colors are a little more refined.
absolutely no idea how is that possible
the colors MUST be identical to the source colors (i.e. w/o vapoursynth at all) on each and every version used
it isn't the question of "colors are a little more refined" or not. IF they're not identical - it's just an error.

Probably right. There is some run to run variance which I think has something to do with my VR setup. I reset everything and tried again and have not been able to replicate the same color experience.
If you want to apply TensorRT-RTX, do this:

1. Close SVP and the player.
2. Make a backup of your "SVP 4" folder.
3. Copy the "SVP 4" folder from the archive on top of yours, overwrite all. Merge it, don't delete or replace your rife folder: SVP's own files in it are still needed.
4. Start SVP and add the switch once: main menu (the vertical dots) > Application settings > "User defined options" tab. Title: TensorRT-RTX (any text), Script name: rife_rtx (this exact name matters), Option scope: FRC profile, Allowed values: ON or OFF, then Add option.
5. Open the RIFE profile you use. At the bottom there is now a "TensorRT-RTX" row under "User defined options", set it to On. Engine stays "NVIDIA TensorRT".
6. Play a video.Off gives stock SVP behaviour. The first time a model or a resolution is used
it prepares the engine by itself, after that it is cached.
Followed your instructions and it works. Thanks for sharing.
I just get this error when playing the next file in the playlist:
This only happens with 'TensorRT-RTX' set to 'on'. When it is 'off' there is no error.
Any idea why this error shows up or how to fix it?
I also tried your R79 and R81 solutions and both work but there is no change to this error showing up when playing next file...

Thanks, I managed to reproduce it: a playlist of 1080p, 720p and 540p files crashed SVP's mpv with the same nvcuda64.dll error. It was a bug in my vstrt_rtx.dll, which released its cached engines in the wrong order once a third video size came along.
Fixed in trt-rtx-svp-2026-10-04.zip in the same Drive folder. Coming from the 09-24 archive, only SVP 4\rife\vstrt_rtx.dll needs replacing (close SVP and the player first).
If it still crashes, tell me your player and the resolutions of the files.

Hello! Vapoursynth has been updated to version 81, and unfortunately, your plugin is no longer working. Could you please update it to support the new API? Thank you!
Vapoursynth has been updated to version 81, and unfortunately, your plugin is no longer working.
R81 dropped the old plugin interface (API 3). That also breaks SVP's own RIFE TensorRT, because its rife\vstrt.dll and rife\akarin.dll are still API 3 for now.
Fix: trt-rtx-svp-2026-10-09.zip in the same Drive folder. Close SVP and the player, then copy its SVP 4 folder over yours. It brings API 4 builds of all of them, sources included.
AI build, use them on your own risk
Ok, to be clear, the current state:
- svpflow libs updated to "API 4" and work with any Vapoursynth version
- vsmlrt IS NOT updated to API 4, and because of this SVP will install Vapoursynth R79.
There're NO performance gains in R81.
There're NO quality or whatever gains in R81.
Performance gains with TRT-RTX are ... questionable. At least it isn't better in ALL cases.

No problems using on-the-fly transcode mod build(s) until I went to do a 23.976 -> 59.940 4hr permanent transcode as I've done hundreds of times in the past. Log complained of unsupported engine build after it was built. Turning off the new switch in the app didn't help. Biggest problem was a 59.524 mismatch which is unacceptable.
Replaced C:\Program Files\SVP 4\rife with BU. Log still had errors. Replaced entire C:\Program Files\SVP 4 but log still had errors. Replaced C:\Users\xxx\AppData\Roaming\SVP4 and log no longer errored. That said, flowgreen's work helps advance the software and is still appreciated. Had I saved all the logs, a further refinement might have been able to diagnose and be fixed but I was in a hurry. That's on me.

It’s great to see that other users are on the same page, especially those experienced users who have been around longer and who know SVP.
