Hi I've just upgrade it the new beta 4 version released here on the forum and it only fixed some weird black square I had in 13.1 version but, my gpu load still at 99% for no reason. I've also uncheck the Graphics overdrive option which should lower the activity on the gpu but it doesn't do it...
I've a Sapphire HD 7950 Vapor-X 3GB GDDR5. I built this computer very recently and I've no idea why is this happening..
