As mentioned in tittle , the problem is that my laptop has 2 GPU's , one that is amd a4 3305m APU with HD graphics (that are HD 6480G) ,and the PCIe controller or whatever its called , picks up the 2nd GPU , that is the HD 7450m (wich has 1GB DDR3 Dedicated memory) .
So the problem here is , when i check GTA5 For example it says 500mb video memory ( wich is most likely the APU's memory that it uses from the RAM , becouse it takes 500mb off my 4gb ram , says i have 4gb and 3,5gb usable) , but the problem is , even if i do have enabled "use high preformance graphics" in the controll center , it still says i have only 500mb , wich it clearly uses from the APU's graphics . And why isnt the secondary gpu's graphics beeing used , it has higher clock + more memory (the weird part is that it says that it is beeing used, with all its 750 core speed , while the APU's graphics has 600 , so technicly it uses it , but doesnt use......its own memory ? How does that work , here is a screenshot of what HWi monitor showed me

So i though that it might be that it doesnt have a dedicated gpu , but yet , my PC screams to me that one of my softwhere isnt installed , and when i look up the hardware id , i get drivers for this particilurar device

Im planning to do a RAM upgrade , since its bottnecking my cpu , becouse its only 4gb and if the GPU doesnt use its 1gb memory , than i dont have a choice but to do so .....Wich is confusing becouse this is what i get from windows expiriance score

It apears to say i do have a dedicated memory , but still incoret ?
So the last thing i am alos getting is this (it says there is a primery adapter (AMD APU's) and a linked adapter wich you can see is in the screenshot )

I have tried alot of drivers offical (non ofical) and with no luck :( myb it can be related to that im using windows 7 ? And when i enable the crosfire i get a amount of 2,5 gb's video memory wich is quite interesting ... but as we know crosfire slows down the preformance and it is unplayable . (tryed on my fav. games)
Im afraid that i cant afford a newer computer , and can only upgrade ram for now....any help on my situation would be apriciated . CPU-z also says that i do have a dedicated gpu with 1gb ,and it isnt used :(

I know that in nvidia control panel you can enable the dedicated gpu and disable the on board. You can also do that in the bios and force it to use the dedicated graphics. I'm not too familiar with radeon software, but im sure its pretty similar.

Hey , thanks for answering , but no , the only thing I can tweak at my bios seems to be to disable switchable graphics or enable them , i had it upgrade BIOS up to 2017.04 (latest) and there seems not to be such a setting , it only has this one where as i said it doesnt change anything unfortunetly ( Only disables the 2ndary gpu :( )
