Wrong Image maybe ?

    I purchased a GMTec G2 N100. Mini PC and a Verbatim Vx500 External Portable SSD USB 3.1 G2 120GB 47441. Flashed the second “generic” librelec image ( the nvidia one ) from a usb drive onto the SSD. Boots into kodi nice and quick. But when trying my locally stored content via PKC, even as low as 720p and sd, video is all stuttering ,freezing. Running the same set up on the PC in windows I can play 4K files smoothly. I flashed the image after using ChatGPT for info , could some one please advise if I flashed the incorrect image ?
