Lynfield detect should be fixed in 0.21+, but I couldn't test since I don't own one. Same for the avx detection. My cpu detect really need fixes, even if it's not blocking, and your can override manually with --archi parameter.

B2BCoin to be added ok. I'll add freelabit too.

The hashrate is very sensitive to pc activity. On a rig, it tends to be stable, but on a real life pc It will drop even when you scroll your files. Jce never runs at high priority, even without --low. if you run it on a pc with no other software running, windows update, Superfetch, and Al. disabled, hashrates should be max and stable.

May launch it without --low with

To give it high priority

Edit: Jce GPU exists as a prototype, I mine with it on my rx500, but absolutely not ready for diffusion yet. In opposition to other miners, I did not reused Wolf0 opencl, but wrote a brand new one (but still in opencl, not CGN assembly). Wolf0 code contains goofs so blatant that it's funny... I beat it on every gpu, but not always Claymore, which is faster, just Claymore 10+ tends to generate a lot of bad shares while 9.7 was a masterpiece of quality. What happened to Claymore ? And 11.3 is the giveup version, it's free but no longer maintained.

Tell me if you're interested into a jce amd, I may finish it and release.
