Hi folks,
well it took some time for me, but finally it is there:
lolMiner-mnx 0.3 
And its the first month birthday of the miner as well - time to party

...
Note that the performance of AMD cards may be limited in Windows, see the commends to set-work-batch below.
--set-work-batchThere are now three special values 2G, AUTO and HIGH. When the work batch is set to 2G the miner is allowed to use 2 gigabytes of graphic memory at most. At level AUTO it will use at most 60% of the graphic cards memory and at level HIGH 90%. Note that AUTO and HIGH operate on per-GPU level, so mixing graphic cards with different memory sizes is no problem.
For Windows and AMD graphic cards there currently is a problem with lolMiner-mnx and the driver preventing that the miner works with more then 2 gigabytes of memory. Therefore the default for the Windows version is 2G, while the default for the Linux version is AUTO. This causes lolMiner-mnx 0.3 to be slightly faster on Linux compared to Windows when using AMD graphic cards.
With blockchain driver on vega, there are no problem with higher work batch. I found that 11 is a good choice for rx vega on win 10 with this driver.
