Thanks for confirming my remark with actual figures. I do believe that it can all be blamed on the driver, and that it was designed that way, but that doesn't really matter - non Quadro readback performance may very well be too limited for certain use cases; I think this is the message to take home. Out of curiosity, can you elaborate as to the cache size differences? Where did you get this information and what differences are there exactly? -- A.
