I got a .gsc for Dolphin, the latest version for x32. Whenever I launch it I go to open my game and it crashes before the game loads, I put graphics to lowest and I think my gpu is broke so it uses my integrated but why will it refuse to work on integrated, is that the problem?
If you're trying to set the GPU inside Dolphin's dropdown window, it doesn't work. You have to make a profile in Nvidia Control Panel to have Dolphin use the high performance Nvidia GPU.
Also, you may want to reinstall your Windows operating system as 64-bit. Your current activation code will work for an install of 64-bit Windows.
Once that's done, you can use the latest dev builds (which are only 64-bit because 32-bit was dropped since it was slower) and enjoy the 40% speed boost of the latest builds.
