Model output not sharp / results much worse than demo (mambairv2_classicSR_Large_x2)

[greasebig]

Description
I tried using the model mambairv2_classicSR_Large_x2 for realworld SR, followed your Colab inference tutorial, but the outputs do not become clearer. The results I get are significantly different from the demo — much lower quality/sharpness.

Expected behavior
Output should match the demo quality (images become noticeably clearer/sharper).

Actual behavior
Output remains blurry / lacks the expected clarity and detail shown in the demo.

Model
mambairv2_classicSR_Large_x2

Steps to reproduce

Run inference with the model (default settings).

Request
Could you help identify why my results differ from the demo and suggest how to reproduce demo-quality outputs? I can provide input/output images and exact commands if needed.

Thanks!

Did you solve the problem? I also met a decrease of performance when training mambairv2_lightSR_x2 (about 0.2dB drop of PSNR on Urban100)
