Hi,

What was the main reason for performance increase?

I optimized a bit the GPU code for compressed key, GPU/GPUHash.h and GPU/GPUCompute.h.
More or less, I factored a bit the HASH calculation of symmetric keys and I added some _synchthreads() in order to try to keep a best synchronization between threads. This gives me a ~5% performance increase on my hardware.

please tell me how to run on radeon rx 570?

VanitySearch supports only CUDA.

Something does not suit me here...
In the original version - four GPU's gave me a score of 6800-7000Mkeys/s.
Current version - keeping the same settings (I only replaced the .exe file) shows 42000-43000Mkeys/s.

This is not possible, especially since the prefix discovery speed has not changed and the GPUs in NVIDIA-SMI themselves show power consumption instead of 240-250W, now 190-200W.

You mean 1.16 gives  6800-7000Mkeys/s and 1.17  42000-43000Mkeys/s ?
Did you wait a bit in order to stabilize the key rate measurement ?
Could you give me your grid size(s) ?
