Hi everyone. I have a slight issue that i wish to revive help on.

 

I have a Lenovo G505s Laptop with and a10 5750m and R5 M230. I have done loads of experiments during this year and have realized on my installation of windows 7, 8.1 and 10 that amd 14.7 RC3 drivers are THE ONLY drivers that actually had switchable graphics working. For example, i told unigine heaven benchmark to run off my high-performance gpu and it ran off that gpu which was great . However, because windows 10 has a huge issue with 14.7 I have been forced to move to a different driver. I have tried every driver from 14.12 to 15.9.1 and switchable graphics just DOES NOT WORK! I tell catalyst that i want my high performance gpu to run games, and also set general switchable graphics option to 'maximize performance'  and run my games. GPU-Z now reports that my R5 M230 is at 0MHZ and under 0% load where as my Igpu (8650g) is at 99% load. Therefore, i can tell that the driver just dosn't recognise or want to kick my R5 gpu out of ULPS mode to start the game. I have even gone and tried lenovo's drivers and they do not seem to work either witch is weird as i thought they should test switchable graphics as it is one of the main features of this laptop!

 

Being a BIOS modder, i have managed to view and modify options in my bios that lenovo has locked. I have attached my options that I have found in my video config tab so someone can look an see if lenovo has done something wrong on their side. Note that these options are still set to  (default).
