using 2 GPUs, one for madvr and the second for Bluesky FRC

(1/3) > >>

midrag:
hey,

i am trying to get frame rate interpolation to work with a second AMD GPU (RX560). My primary GPU (RTX 2080) is doing well with madvr but can't do the framerate interpolation.

what i've done:

- setup the 2080 as primary video card and configured madvr
- installed the RX 560 and their drivers
- enabled AMD Fluid Motion
- installed Bluesky FRC (https://bluesky23.yukishigure.com/en/BlueskyFRC.html)

now i tried the custom video mode and added a LAV Filter so that the framerateconverter is used (i needed to actived the "global mode" of the Bluesky FRC).

The interpolation is working great. i get nice 4k 60hz videoplayback. Unfortunatly the HDR to SDR conversation of madvr is not working. I asume a LAV Filter can not deal with it.

Has anybody here a working configuration with 2 GPUs?
Any ideas what i can try next?

I don't understand what you are doing

How are you expecting to use 2 different GPUs in one system?

midrag:
The first GPU is for rendering / upscaling. Basically completely for madvr.
The second GPU is only for frameinterpolation (24hz -> 60hz).

The “cheaper” 4K beamers don’t have the ability to do frameinterpolation.

The trick is to spent about 100$ and do the frameinterpolation on the pc side.

It could be done with one card and software like SVP (https://www.svp-team.com/), but the solution with the second card is better.

It works with MPC and other players.

I get what you want to do, I'm asking how you expect to use 2 GPUs in one system?

midrag:
It is already working!
The Bluesky frame rate converter is configured to use the AMD card.
Madvr and JRiver use the primary gpu (in my case Nvidia).
I am only missing the hdr tone mapping.
