my main computer is broken, so I am now using my old laptop (HP Pavilion g6), I put a disk from the main computer into it and wanted to play some games, at first CS GO(D3D device error) did not work for me, but after updating the drivers to the newest available on the Radeon HD7670M video card, I began to lag any games and programs on Unity and UE (for example: in cs go at high 70-80 fps, in BTD 6 - 15-20 fps), reinstalling drivers does not help in any way, old drivers are not installed on Win 10, and the problem is only in games on Unity and UE, on other engines no have problems
