[QUOTE="tourettes, post: 548341, member: 10858"] Just an idea for optimization. As the data amount the LEDs can display is pretty limited, it would be possible to blit the backbuffer to a new (much smaller texture) inside GPU and then just copy that to the RAM. It would save the bus bandwidth during the transfer and CPU cycles when analyzing the picture. 100 x 100 picture should be already enough? And it would give HUGE boost on the performance. [/QUOTE]
