I have already compiled one for me. Time to depth for more threads seems quite improved.
(even noticable on my hardware compared to r305 nopopcount release)
Note that default for Threads for r323 is 8!
This is the reason:

FoxSEE 7.17.0
Thanks to the Author Zixiao Han :sm36:
https://github.com/redsalmon91/FoxSEE/r ... ag/v7.17.0
Updates :
- Re-wrote q_search; start to use transposition table in q_search (share the same table with ab_search); removed dangerous cutoffs on pv nodes
- Carefully selected where to fail-hard and where to fail-soft
- Removed Aspiration Window (as a result of fail-hard/soft change, because it causes search instability otherwise)
- Added Razoring with a safe margin
- Added back Mate-Threat Extension to guard Razoring & Reversed Futility Pruning
- Added Time Pruning (another new experimental idea, see wiki for explaination)
- Slightly modified evaluation (mostly around passers)

Needs more games, but unlikely to change too much.
unfortunately I found some bugs after the release, but they don't seem to impact the strength (aspiration window overflow when close to mate, score ocillations in fine #70, failure to resolve some mates). fixing them might impact strength in theory though - so I'll probably keep the release as is
Certain engines are hard to beat even if they are close in strength like Komodo 9 :roll:
1: Komodo-9.02-64bit 7.0/10 ·········· 1=1==1=1== 21.00
2: Cheng4_x64 3.0/10 0=0==0=0== ·········· 21.00
