So, i have 2 graphic card on my laptop Acer Aspire 4830TG. which is Intel(R) HD Graphics 3000 and NVDIA GeForce GT 540M. when i try to run games it will say that they are unable to detect a graphics card. then i try to disable one of them from device manager > display adapters. when i disable the NVDIA, the game runs but with very poor graphic, and pixelated. then when i try disabling the Intel graphics, the game runs but with very poor fps. then i tried it again without disabling neither of them, and the games went back to saying no graphics card detected. any suggestion?
