It's using the same code ported from lczero FWIW so performance is going to be rather similar, not sure why you think it'd be faster. I checked and the only relevant change seems to be ispc support, but that's a day old and isn't going to be in the release.

Leela Zero now has (4x4, 3x3) Winograd support (larger tiles) but I think that hasn't been backported to lc0 yet.
In Lc0 batch size can be changed in LeelaChees Zero it can't. When one has strong machine with a lot of CPUs like TCEC machine Lc0 with larger batch size will be faster than LeelaChess Zero.

- without syzygy support (0.10 had)
- you can not see the calculation process, just after x s throws out the result, how some dubious Thinker WB engine
- and most importantly, some error messages - the opencl version. After two games I had to stop the game and play version 0.10 ... I can not give exact mistakes, I'm at work, perhaps in the evening.
