Hi, I have an old Intel GMA 950 (chipset 945 GM), tried the last stable Batocera (5.21) and, although it works fine without any kind of shader (for example, Super Nintendo), as soon as I add a shader it goes incredibly slow (maybe 1 frame every 6 or 8 seconds). I suppose the video processing is directly done by the CPU and not by the graphic card. I read in internet that intel GMA supports until OpenGL 1.4. I also tried the special build for intel cards, same luck. The shader combination I wish is hq2x + bilinear filter, which shouldn't be a problem for this card.
Does somebody know if a certain older version of batocera supports OpenGL 1.4, or at least, direct hardware acceleration with the Intel GMA 950?
