[QUOTE="Blue Energy, post: 695732, member: 109162"] Thank-you for that explanation! I wonder why the codec is required at all for decompression when the graphics card supports the format? So, what I gleen from your excellent primer is that the typical bottlenecks here are disk speed and mismatched codec/gcard. These days, needing a faster hard drive is easy to fix. Mismatched codec and graphics card though... how do you assure that the card you're using is capable of working with the codec besides assuring that the graphics card says that it supports h.246? Of the three respondants so far, all three use graphics cards which claim to support h.246 - but ones system doesn't work very well. Would you conclude that his difficulty is elsewhere or is claiming h.246 in gcard specs not necessarily specific enough? As for Hard Drives - I'm planning to check the throughput claims by the manufacturer if I get responses regarding the specific drives. If that doesn't pan out as a difference maker - there is a big difference in processing power between the one system that doesn't work and the two that do. If all other things are relatively equal, presuming no user error, it must be the processor. [/QUOTE]
