Fl4shMiner v1.2.1

• Added support for the PearlHash algorithm used by Pearl (PRL).
• Added optimized NVIDIA CUDA kernels.
• Added support for NVIDIA GPUs based on the following architectures:
• RTX 30 Series - Ampere
• RTX 40 Series - Ada Lovelace

Support for additional NVIDIA architectures will be added in future releases.

Tested performance:

GPU	Hashrate	Core Clock Offset	Locked Core Clock	Memory Clock	Power Limit
RTX 3060 Ti	~67.40 TH/s	+225 MHz	1825 MHz	Locked at 5001 MHz	168 W
RTX 3070	~74.50 TH/s	+250 MHz	1650 MHz	Locked at 5001 MHz	175 W
RTX 3080	~108 TH/s	+250 MHz	1605 MHz	Locked at 5001 MHz	265 W
RTX 3080 Ti	~128 TH/s	+250 MHz	1605 MHz	Locked at 5001 MHz	299 W
RTX 4090	~300.00 TH/s	+250 MHz	2500 MHz	Locked at 5001 MHz	397 W

Dev fee 1.5%

Hashrate and power consumption may vary depending on the GPU model, silicon quality, driver version, operating system, overclock settings, and temperature.

### CPAY, CSD and FXL users: keep using v1.2.0, because v1.2.1 caused a regression on these algorithms. I'm investigating it.

Update: Fixed . The regression affecting CPAY, CSD, and FXL has been resolved. You can safely upgrade.
