@Zombeaver I use Upscayl for most my image upscaling nowadays. You can find some extra models for Upscayl here if you wanted to see if you can get better results. https://github.com/upscayl/custom-models/blob/main/README.md

AI upscaling is not going to get you perfect results however. It's not there yet. I almost always spend quite a bit of time in Photoshop after the fact fixing shitty lines or messed up text.

 

If you have time to put towards it you may get best results tweaking the process a bit more with something like chaiNNer. might be a better option but will have a steeper learning curve. https://github.com/chaiNNer-org/chaiNNer

I have Photoshop. I'd like to avoid another monthly subscription just for this so imgupscaler is probably out (and as a side note I seriously hate this pricing structure that a lot of these sites have of pay per number of images processed, that entire model would be unusable for my needs). I've heard of topaz, and looking into it a bit it looks like you can pay once and then use local software, which is much more appealing to me. I'm a little concerned about the fact that it says includes 12 months of updates though - does the software outright stop working after 12 months if you don't pay again or does it just not receive updates anymore (this is implied but I want to be sure)?

I'd be leery of the former but if it's the latter that could work. 

Definitely! I'll send some examples in a couple hours. Thanks for the offer!

topaz continues to work after 12 months, you just don't get updates to the software. It's a dumb plan. but the software is good, been using it for a few years now without updates, honestly never noticed what the updates did.

Yeah that's fine and to be expected. I'm used to that kind of thing already. There have been some cases where something was so bad that I just completely recreated it from scratch using closely approximated fonts/colors, etc.

Really good tip here! Doing some quick testing 4xHFA2k and 4xNomos8kSC seem to be yielding the best results so far. 4xHFA2k has been consistently a bit better between the two though, with less weirdness in font interpolation.

That's good to know! I'm not totally opposed to dropping a one time amount of $100 on something like this if I need to. In no dimension would I ever pay $10-$30 a month until the end of time for a finite number of images per month though. That's an insane pricing structure.

I appreciate the tips here from everybody! This definitely points me in the right direction. I'm liking Upscayl quite a bit so far. It's really easy to use, has a nice UI, is fast, yields pretty good results so far, and is free.

Some examples of some lower quality material:

4xHFA2k:

The second one here seems to be the most problematic, with a fair number of oddities in the text. A few things here and there in the Lunar Leeper one too, but overall not too bad. I probably would use the first and third one here as replacements.

my attempt at lunar leeper. (still tweaking though)

Here's that second page upscaled with topaz for comparison. To me it's slightly more readable although a bit more blurry.

This looks similar to the results from Nomos8kSC in Upscayl and demonstrates some of the same font weirdness. This is particularly evident in section 4 of that page.

Nomos8kSC for comparison:

I almost wonder if it wouldn't be beneficial to run some of these through multiple models in sequence with each at smaller integer scales.

Thank you for the comparison, that's good to see as an example. I don't think either one looks particularly great honestly. Both of them look what I would describe as "weird" on quick glance. It would be pretty obvious to me that it had gone through some kind of digital tampering in both cases. The other two less so.

I wish there was a model that was specifically trained for text, but to my knowledge there isn't one.

I've had decent success with the upscaling efforts so far. You can find some examples below. You can click the drop-down to select different images to compare.

Those results are really good. What a time to be alive where things can be rejuvenated like that. Wonder if I could put myself through AI?
