| Measured fixture results | Tested scale: 4× | Tested scale: 2× |
| Fixture findings | Ran 4× upscaling locally with noise reduction and text retention; speed depends on the device. | 2x free export (1024×1024 JPEG) reaches PSNR 26.97 dB and SSIM 0.8870; brass robot and wooden sign lettering are crisp, while fine calibration lines reflect the 2x ceiling. |
| Original historical observation | Waifu2x Unlimited (Swin-UNet Photo 4x) suppresses JPEG compression artifacts cleanly while preserving natural camera gradients (PSNR 28.34 dB, SSIM 0.895) in 2.63s via WebGPU, without introducing fake generative hallucinations. | 2x free export (1024×1024 JPEG) achieves PSNR 26.97 dB and SSIM 0.8870 against the 2048px GT; brass robot and 'REALTEST 2026' sign are sharp, while 4x HD (2048×2048) is reserved for paid members. |
