Hey @VMike,
as you may have noticed when using Waifu2x, it is very CPU-intensive !
My AMD FX 6300 can take up to 2 minutes to upscale to a 2k image, let alone for 4k...
For real-time upscaling, it needs to be much faster than that, at least 30 images per second.

The only way for it to be practical way would be to make use of GPU acceleration (via CUDA or OpenCL) but even then,
it would require a powerful GPU (at least a Titan), fast storage (Samsung SSD), fast DDR4 memory etc...
Not impossible but very impractical for most people.

Also, Waifu2x would be best suited for visual games and games with anime-styled graphics.
Resident Evil looks interesting with Waifu2x, almost like a painting.
But for now, it's best suited for still pictures and maybe movies (if you are doing frame-by-frame).

There is a version using cuda. I think that is also open sourse. Yes it is slow, with my 980ti it takes about 20 seconds to scale 320x240 32 times the size. It was just that I read that someone claims he has it got running for 30 fps. And I dont think it is impossible.

I really want this for those old pre-rendered psone games. I have not seen any other filter that makes them look so good.

Thank you for your answer.
In those pictures I have taken an image from the emulator while it runs in 320x240. Its wierd, because when it is pre-rendered games like Final Fantasy and Resident Evil they actualy looks better if the source is in original resolution. I have contacted a guy on twitter as well who claims that it should be easy to make Waifu2x run in 30fps if the image is small enough. I hope 320x240 is small enough.

Could someone make like an overlay you just could add over an emulator window wich uses Waifu2x? Its wierd, because everywhere else I have asked they have said that it is impossible to make it run fast enough for Ps1 emulation.

Yeah I really, really like that look it gives the game. Would be extremely nice if someone could make it work.

Here are some pictures of Resident Evil 2 320x240 screenshots upscaled with Waifu2x.




I also added some minor ReShade to them. Gaussian flare and some sharpening. Well, compared to the originals.. this looks like gold. At least to me

Hello.
First I want to say sorry that I dug up this old thread. I just accidently stumbled on it in my persue for info.
So I registered here to write a reply in this thread.
It is about Waifu2x that I think makes old games look soooo good. Here arw some pictures of Waifu2x 32x with highest noise reduction over Final Fantasy VII. It is first rendered in the standard resolution of 320x240 unstretched wich gives Waifu2x best results.

Now, I know there are other filters for Ps1 emulation but none I have ever seen gives such nice result.
I have asked around everywhere but always get thevsame answer; No, Waifu2x is not possible to run in realtime.
And I have kinda given up. But since I got nothing to lose I tought I might as well try here. If anyone is up for the task, I would even pay a little to have Waifu2x filtering my Ps1 emulators in real time.
Oh well. Thanx for reading anyway
