Dealing with some artifacts

[trsh]

Dear nvidia, do you have any idea or advice, on what would cause the ugly line on the front box?

can you try NIS_CLAMP_OUTPUT = 1 in your defines? Also try to use a bit less sharpness Are you using NIS with HDR?

NIS_CLAMP_OUTPUT did not make a difference. HDR is = NISHDRMode::None. Sharpness can be 0, and same line.

Sharpness 0 + NIS_CLAMP_OUTPUT

What is the scale ratio? Do you have an image that we can use for debugging?

[trsh]

in_x = 640
in_y = 360
out_x = 1280
out_y = 720

This should be the texture, that is upscaled

@trsh, Thank you Janis. We'll take a look.

Anything new around this?

@trsh. We have not being able to repro the strong artifacts on the lines, but we observed some overshooting on the edges specially with large sharpness values. The image is already very sharp and applying sharpening on top can result on overshooting. We're investigating using a different detection ratio as well as an attenuated LTI function that might help with this specific case.

Strange that you were not able to reproduce. Then it should be something off with my setup!?
