I have previously reported some windows updates changed some of the performance of the 0.1.4 version... but I got mistaken by the fact that I am using the second GPU for my monitor... and the AMD driver has a "flaw" (in my opinion...) that when the first card to be detected over the PCIe has no Display adapter connected to the RAMDAC... it does not "turn on the full potential of the GPU"...
Workaround:
Simple connect a display there.. you don't use.. or plug-in and plug-out the other card display just to "activate" the RAMDAC...
I had no time to investigate further yet... just reporting.
My drivers are 13.12 (win 7 x86_64)
Just to be sure it's not related to my GPU type, i am using:
PCIe 1: R9 270X
PCIe 2: nothing
PCIe 3: R9 290X (monitor connected)
MOtherboard: ASUS GENE II
NOTE: I guess that while there is no way to say to old BIOS (like X58 chipsets like mine) which is the "main" adapter... where you use your display screen... this will be a problem. But it lacks fixing... as for my logic.. it's considered a driver bug.. to identify the GPU as non-fully-functional...
