Accuracy of different implem

1 - 10

2025-06-27 01:12:40	Beware than ffvship can be less accurate than vship because it transmits uint16 instead of float to the gpu

FFVship is very slightly different from VSHIP.

Lumen

2025-06-27 01:13:45

Usually a bit higher score

𝕰𝖒𝖗𝖊

2025-06-27 01:13:56	I think it's totally worth with the speed benefit.
2025-06-27 01:14:05	If you use the same impl; it doesn't matter for comparison.
2025-06-27 01:14:19	Or for direct quality testing; the margin of difference shouldn't matter anyways

sadly vship is not hardware agnostic which makes it ill suited for my needs.

Lumen

2025-06-27 02:15:20

If only projects like chipstar were more mature...
