uploading that much data to the video card and then using the hardware scaling may be slower than keeping the image in RAM, scaling on the CPU and then doing the data transfer to the card. in theory it shouldn't be, but since the GPU isn't just being used for this (but also for kwin compositing and any other app running and doing things) and since the advertised maximum texture size is still often 2048x2048 such large images can really put a burden on graphics system. for smaller images, you're absolutely right though. regardless, i don't think it makes any sense to store that much data in either VRAM or RAM for an image that is 99% of the time going to be the same size which is likely much smaller than the actual resolution. -- Aaron J.
