AI Remastered from SD to HD quality

Something doesn't seem right with that (lack of) speed.

I just tried Waifu2x to upscale from 640x480 to 1920x1080 on a RTX 3060 and RTX 3090 (both power limited to 90%). Using the waifu2x-ncnn-vulkan engine.

It took about 4 minutes to write the split frames. After that, on the 3060 it up-scaled ~1.1x real-time and on the 3090 ~2.0x real-time. VRAM use was ~9 GB.

man would u be as nice as throwing a screenshot or 2 of your settings. On my end, I'm getting nowhere near the 1.1x your talking about on my 3060 using waifu2x-ncnn-vulkan.

Here you go. I didn't change any settings in Waifu2x - just set the scale ratio.

I did 2x upscale from 1920x1080 using RTX3090 and RTX3060 and a 2x upscale from 640x480 just using the RTX3060. Each upscale used only one GPU. I.e., not using the multi-gpu option.

Note that I've further lowered the power-limit on my gpus since I previously tried this (were limited to 90%, now to 75%) which probably slowed them down a bit.

Source was the music video for Machinehead, in the two different source resolutions. It is 4:13 long. Processing times below include writing the split frames.

RTX3090 1920x1080 x2 upscale took 13:08 = 0.32 real-time


RTX3060 1920x1080 x2 upscale took 22:13 = 0.19 real-time


RTX3060 640x480 x2 upscale took 3:43 = 1.14 real-time
