[QUOTE="tourettes, post: 827062, member: 10858"] Do you have an access to Nvidia GPU? Before any ATI fanatic jumps on my face - it is known that ATI (and Intel) have really bad performance when you need to copy texture data from GPU merory to RAM. So, it would be nice to see if the íssue is caused by bad memory bandwith in "non-normal" direction. If using Nvidia GPU helps then there is two possibilities to help ATI / Intel users, but they require changes to MP itself: 1) allow plugins to write some pixel shader code and process the video frames directly in GPU memory space 2) allow plugins to copy downscaled textures for processing (IFC would work almost as good even if the video frame would be scaled to 25% - few missed lines in accuracy is quite good compromize when comparing to stuttering) [/QUOTE]
