I use an (old) Dell Vostro 3450 ( i5, around 2011
) with a AMD Radeon 6630M GPU.
but Avenue 6 run ok on this laptop, for my current use.
Good News :
I uninstalled and re install the GPU driver, et now DXV video are displayed ok.
I made a reset of the "graphique commutable" fonction too (between the internal intel video card and the AMD one).
So I don't know why, but it works.
One small problem, perhaps independant :
in AVENUE7, Preview thumbnail and video display are BLACK for DXV files including one only frame
(for picture display).
Other normal DXV files are OK.
in Avenue6, everything is OK, on the same PC.
Here is a 1 frame DXV file for test :

Thanks for all.
