Zero Squeegee

Pamagajo, had the same issue...open the gpu table (I used the SublimeText editor, it keeps line breaks in one piece), go down to line 451, youll see one for NVIDIA GTX 780M. Copy that whole line, paste a copy on the next two lines, and add entries for the 880M and 980M. Lines will look something like the following: NVIDIA GTX 880M .*NVIDIA .*GTX *88[0-9]M.* 5 1 0 4.3 NVIDIA GTX 980M .*NVIDIA .*GTX *98[0-9]M.* 5 1 0 4.3 Next time you start the viewer, it should notify you that your graphics card changed from the GEForce Lulz (or something like that.)
