SPP and GPU acceleration

Yesterday I replaced the video card on the test computer.

The computer has the following configuration - Win 11/ 64 / i7 /24GB DDR4-2133/ Video Card ASUS GeForce GTX 660 2Gb GDDR5 / SSD 256Gb SATA

New video card - COLORFUL GeForce RTX 3060 LHR 12288Mb NB DUO (RTX 3060 NB DUO 12Gb GDDR6 V2 L-V)

The computer has all the system updates installed and only 2 programs - DxO PhotoLab and SPP - the latest versions. I've tested the conversion speed of the same 5 X3F files and 5 X3i files to TIFF 16bit with GPU accelaration enabled.

With old video card - 3 min 6 sec
With new video card - 1 min 58 sec
With old video card - 6 min 47 sec
With new video card - 6 min 48 sec

Conclusion: The conversion of X3i in SPP doesn't use GPU and the code is not optimized for it.

For example: the result of conversion of 5 Pef files (Pentax K-1 Mark II) in DxO PhotoLab with the "slowest" DeepPrime noise reduction:

With old video card - 42 min 18 sec
With new video card - 1 min 02 sec
