I remember when applications where first being written to use direct draw on the ppc... we were told it would have a great improvement over older apps with video frame rates and code efficiency.
So, why is it that some newer devices (such as the Titan) have WORSE performance using Direct Draw apps than older devices with slower CPUs?
My experience with DD coding is slim to none, but as I understand it, isn't direct draw just a driver to allow for standard graphic routines with varying non-standard hardware?
Did HTC just write some bad drivers for the new hardware? Or is it something deeper? Benchmarks on the hardware yeild above-average graphics performance, and programs (such as TCMP) run fine when direct draw is disabled. So, it seem DD is the culprit. Why would this be?
