@jbinkley60 Thank you for your feedback, and for providing the version comparison — that’s very helpful.
We have logged the issue: the Standard vs. High Quality setting for AiUpscaler and RTX RapidAI Upscaler appears to have no effect in version 4.1.0.3 and later, while it worked correctly in 4.0.7.0. This may be a regression, and we have forwarded it to our engineering team for investigation.
