Hi!

Toshiba Satellite L50B
Windows 8.1 pro 64bit
Intel Core i7 4510
RAM 8 Go
AMD Radeon R7 M260 2GO + Intel HD Graphic 4400

So in Device Manager i have both gpu drivers installed from Toshiba's website,
but when i screen resolution>advanced settings i only find the intel internal card with total memory 1.7 gb, and both dedicated and system memories with 0MB
i tried installing the driver from the amd site but nothing changed, also disabled the intel graphic card but still the amd didn't show up it says something like microsoft standard card with 253MB total memory.
btw i still have 1go to download from the windows updated because i just upgraded to win 8.1 from win 8 pro, if this could be related to the issue.
any help would be greatly appreciated :)
