Alex_M Posted March 10, 2023 Posted March 10, 2023 Photo renders images with Unsharp Mask filter differently when using Hardware Acceleration. Please see the screenshots below. Notice how the edges of the treeline are sharper/more aliased when using Hardware Acceleration (GPU).

walt.farrell Posted March 10, 2023 Posted March 10, 2023 That seems more appropriate to report as a Bug, @Alex_M. The results should be the same, assuming you don't have a buggy GPU driver (which is also a possibility).

I am not certain if there is a "real" difference between hardware acceleration on and off in this case. I performed some tests with one of my pictures with a live unsharp mask filter applied. Results: (1) Export to jpg: identical from hardware acceleration on and off. (2) Screenshots from pictures open in AP, 1:1 (100%) representation: identical from hardware acceleration on and off. (3) Screenshots from pictures open in AP, representation other than 100%: visible differences from hardware acceleration on and off. Bottom line: rendering in AP is only approximate for representations other than 100%, screenshots are not really suited for comparisons. You should export your pictures with hardware acceleration on and off and see if the results are different.
