From what I’ve seen on YouTube, most people recommend the 6600 or above to achieve proper LSFG at decent quality. Video encoding is not the issue for me, as I could still do that on my 4080 Super (AV1 especially) without noticeable performance loss — I already do that.William Sokol Erhard wrote: ↑07 Apr 2025, 16:08I will also note that unfortunately the Radeon 6800 is not exceptional for video encoding compared to Intel's GPUs or particularly Nvidia's recent high end GPUs. The top end 4000 and especially 5000 series Nvidia GPUs have made massive leaps in video encoding performance.
It should be fine for 1440p upscaling using LSSFG's lightweight optical flow accelerator based interpolation as long as you use a low and consistent multiplier factor.
Basically, I would use the 6800 only as the FG GPU. Apparently, AMD has their own FG now (AFMF or something like that), so there may even be different avenues towards the same goal.
I am currently ill, and until the holidays in May, my job will keep me very busy, but if I try that stuff, I will report back.
