Though my question wasn't really about the HUD as such, I was wondering where they were moving to/from - I guess the answer may be too obvious, but just to confirm. I assume it's across PCIE to the card (or maybe from/both) - is it DMA or CPU transfer? Is it dependent on app behavior or driver - eg. running Unigine Reflections I saw a blip in the graph first run, but not again.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
