I had this same issue. For some reason even though LB is portable, when I moved its folder to another drive, it broke the path link to roms stored outside of LB folder. Example... D:\Games\roms\game1.7z After I moved LB folder to new drive, paths for all roms where broken as shown in LB as... ..\Games\roms\game1.7z As you can see LB removed the drive letter, but this is easy to fix. Open the .xml within LaunchBox\Data\Platforms folder, and use find and replace to add drive letter back.

I had similar issue, but changing Nvidia to 'prefer maximum performance' fixed it for me. · Right click on desktop > Nvidia Control Panel · Manager 3D Settings > Program Settings > Add > LaunchBox · Power management mode > Prefer maximum performance
