My laptop is a Lenovo Ideapad 320-15abr
Ram 8 gb
Integrated graphic card Radeon R5 Graphics
Other graphic card Radeon R8 M535DX
The problem is that it lags terribly when I watch films and also when I play videogames it lags a bit even if it shouldn't because the games are old and I don't set the graphics to the maximum quality.
Also, when I use the task manager it shows two graphic cards, but they are both R5. I think the lag is due to the fact that games and films run on the integrated card instead of the R8 but I don't know how to fix this problem. I already tried updating the drivers but it didn't solve anything.
What should I do?
