Hi Andrew, and everyone else.. I am sorry about the drunk rant a while back, I really was very tilted by the software issues...
If it is of any interest, I have been doing some casual research, with some intriguing results....
I have mentioned previously that I usually run Windows 7 in a VM on a Linux (openSuse) host. I have now for comparison, a clean (native) install of Windows 10, with all up-to date drivers etc.
The first thing I will say that it IS better.. but it still is horribly demanding, in particular of CPU
My machine is no gaming beast, but is a perfectly adequate machine (It runs GTA V eg!)
(AMD Phenom II x4 905E, 8Gb Ram, R9 270)
I don't want to fill the forum with clutters of pictures.. BUT....
If I have the "Challenges" open in the main lobby (which is my usual), ie the screen showing what hands I need to get the next increment, ONE of my CPU's % load doubles, and temps go up, fans come on etc. The other cores show an increase in loads as well. This is instant and 100% reproducible. If I go back from that screen, the load instantly drops back to parity with the other CPU cores, which also drop back.
Would you pass this on to the the Likely Lads of Lithuania, please... . (Damn. Estonia does not alliterate.) (Leave it in anyway).
ps This does not noticeably happen when in the VM, but loads caused by the Unibet SW are so high anyway, that it might not show up...
If anyone apart from Andrew has got this far, it would, I think, be helpful if you have monitoring SW to try this. Even if you have a massively powerful PC, but especially if you have a quad-core AMD.
