May I know WHY you posted new version in a separate thread AGAIN? If it´s an upgrade (new features, tweaked code etc.) IT WOULD BE FAR BETTER to have only one thread - Jan Ondrus started it.
If you are disagree with my statement, consider an extreme case - we decided to make new thread for every new paq8px version. Result? Complicated navigation through many irrelevant threads.
So please stop that, otherwise I report you to Shelwien.
Please hit the "THANKS" button under my post if its useful for you.
@suryakandau:
Don't mind him. In your case its better to make new threads.
Or even better if you'd just use one thread for all of your clones of codecs.
@CompressMaster:
Do you really want *sk versions in main threads of these codecs?

Thanks. May I ask why you don't use a Source Control repository? Something like GitHub or Gitlab can be really convenient. We do this with paq8px and @kaitz does it with paq8pxd and paq8pxv.

Hm...Compresses 0.4% stronger and 65% slower (compared to fp8v6). Good!

Please don't post these in GDC discussion thread - its for contest discussion, not for benchmarks.
Also fp8 doesn't seem fast enough even for the slowest category anyway, it has to be more than twice faster to fit.
Fp8sk12
-faster than previous version but worse compression ratio

if it run under Intel Socket 1151 Core i7-8700K (Coffee Lake, 3.7GHz, 6C12T, 95W TDP) how fast it could be ??
