MultiGPU Verify Usage on Windows
#1
Bug 
How can I VERIFY beyond a shadow of a doubt that BOTH GPU's are being utilized? You see,

IT SAYS BOTH GPUS are being used, however the performance is IDENTICAL to that of ONLY THE FIRST GPU (GTX470) which tells me that ONLY the 470 is being used. If the 275 were also being used, the speed would be > 1000.00M/s.

didnt you see this message?

mixed gpu types are no longer supported. well you can run multiple instances using -d option.

Ok, I knew something was strange. I guess I wasn't paying attention, that little piece of news must have escaped me during the last few versions. Thanks I guess this is the good opportunity to start selling of "lower-end" cards and replacing them with newer ones with identical GPU.

btw i knew about -d, its just I was going -d 1,2 instead of making separate sessions.

Mixed GPU support added to latest version, thread closed.
